## Detailed Description

Defines the functionality of a 3D API.

Remarks
  The RenderSystem class provides a base interface which abstracts the general functionality of the 3D API e.g. Direct3D or OpenGL. Whilst a few of the general methods have implementations, most of this class is abstract, requiring a subclass based on a specific API to be constructed to provide the full functionality. Note there are 2 levels to the interface - one which will be used often by the caller of the Ogre library, and one which is at a lower level and will be used by the other classes provided by Ogre. These lower level methods are prefixed with '_' to differentiate them. The advanced user of the library may use these lower level methods to access the 3D API at a more fundamental level (dealing direct with render states and rendering primitives), but still benefiting from Ogre's abstraction of exactly which 3D API is in use.

## Member Function Documentation

## _applyObliqueDepthProjection()

virtual void Ogre::RenderSystem::_applyObliqueDepthProjection | ( | Matrix4 & | matrix,
|  | const Plane & | plane,
|  | bool | forGpuProgram
| ) |  |

pure virtual

Update a perspective projection matrix to use 'oblique depth projection'.

Remarks
  This method can be used to change the nature of a perspective transform in order to make the near plane not perpendicular to the camera view direction, but to be at some different orientation. This can be useful for performing arbitrary clipping (e.g. to a reflection plane) which could otherwise only be done using user clip planes, which are more expensive, and not necessarily supported on all cards.

Parameters

  matrix | The existing projection matrix. Note that this must be a perspective transform (not orthographic), and must not have already been altered by this method. The matrix will be altered in-place.
  plane | The plane which is to be used as the clipping plane. This plane must be in CAMERA (view) space.
  forGpuProgram | Is this for use with a Gpu program or fixed-function

## _beginFrame()

virtual void Ogre::RenderSystem::_beginFrame | ( | void |  | ) |

pure virtual

Signifies the beginning of a frame, i.e.

the start of rendering on a single viewport. Will occur several times per complete frame if multiple viewports exist.

## _beginGeometryCount()

virtual void Ogre::RenderSystem::_beginGeometryCount | ( | void |  | ) |

virtual

The RenderSystem will keep a count of tris rendered, this resets the count.

## _cleanupDepthBuffers()

void Ogre::RenderSystem::_cleanupDepthBuffers | ( | bool | bCleanManualBuffers = `true` | ) |

Removes all depth buffers.

Should be called on device lost and shutdown

Remarks
  Advanced users can call this directly with bCleanManualBuffers=false to remove all depth buffers created for RTTs; when they think the pool has grown too big or they've used lots of depth buffers they don't need anymore, freeing GPU RAM.

## _convertProjectionMatrix()

virtual void Ogre::RenderSystem::_convertProjectionMatrix | ( | const Matrix4 & | matrix,
|  | Matrix4 & | dest,
|  | bool | forGpuProgram = `false`
| ) |  |

pure virtual

Converts a uniform projection matrix to suitable for this render system.

Remarks
  Because different APIs have different requirements (some incompatible) for the projection matrix, this method allows each to implement their own correctly and pass back a generic OGRE matrix for storage in the engine.

## _createDepthBufferFor()

virtual DepthBuffer* Ogre::RenderSystem::_createDepthBufferFor | ( | RenderTarget * | renderTarget | ) |

pure virtual

Creates a DepthBuffer that can be attached to the specified RenderTarget.

Remarks
  It doesn't attach anything, it just returns a pointer to a new DepthBuffer Caller is responsible for putting this buffer into the right pool, for attaching, and deleting it. Here's where API-specific magic happens. Don't call this directly unless you know what you're doing.

## _createRenderWindow()

virtual RenderWindow* Ogre::RenderSystem::_createRenderWindow | ( | const String & | name,
|  | unsigned int | width,
|  | unsigned int | height,
|  | bool | fullScreen,
|  | const NameValuePairList * | miscParams = `0`
| ) |  |

pure virtual

Creates a new rendering window.

Remarks
  This method creates a new rendering window as specified by the paramteters. The rendering system could be responible for only a single window (e.g. in the case of a game), or could be in charge of multiple ones (in the case of a level editor). The option to create the window as a child of another is therefore given. This method will create an appropriate subclass of RenderWindow depending on the API and platform implementation.

  After creation, this window can be retrieved using getRenderTarget().

Parameters

  name | The name of the window. Used in other methods later like setRenderTarget and getRenderTarget.
  width | The width of the new window.
  height | The height of the new window.
  fullScreen | Specify true to make the window full screen without borders, title bar or menu bar.

  miscParams

  A NameValuePairList describing the other parameters for the new rendering window. Options are case sensitive. Unrecognised parameters will be ignored silently. These values might be platform dependent, but these are present for all platforms unless indicated otherwise:

  Key | Type/Values | Default | Description | Notes
  title | Any string | RenderTarget name | The title of the window that will appear in the title bar |

  externalGLControl

  true, false

  false

  Let the external window control OpenGL i.e. don't select a pixel format for the window, do not change v-sync and do not swap buffer. When set to true, the calling application is responsible of OpenGL initialization and buffer swapping. It should also create an OpenGL context for its own rendering, Ogre will create one for its use. Then the calling application must also enable Ogre OpenGL context before calling any Ogre function and restore its OpenGL context after these calls.

  macAPICocoaUseNSView

  bool "true" or "false"

  "false"

  On the Mac platform the most diffused method to embed OGRE in a custom application is to use Interface Builder and add to the interface an instance of OgreView. The pointer to this instance is then used as "externalWindowHandle". However, there are cases where you are NOT using Interface Builder and you get the Cocoa NSView* of an existing interface. For example, this is happens when you want to render into a Java/AWT interface. In short, by setting this flag to "true" the Ogre::Root::createRenderWindow interprets the "externalWindowHandle" as a NSView* instead of an OgreView*. See OgreOSXCocoaView.h/mm.

  contentScalingFactor

  Positive Float greater than 1.0

  The default content scaling factor of the screen

  Specifies the CAEAGLLayer content scaling factor. Only supported on iOS 4 or greater. This can be useful to limit the resolution of the OpenGL ES backing store. For example, the iPhone 4's native resolution is 960 x 640. Windows are always 320 x 480, if you would like to limit the display to 720 x 480, specify 1.5 as the scaling factor.

virtual

## _getDefaultViewportMaterialScheme()

virtual const String& Ogre::RenderSystem::_getDefaultViewportMaterialScheme | ( | void |  | ) | const

virtual

Returns the default material scheme used by the render system.

Systems that use the RTSS to emulate a fixed function pipeline (e.g. OpenGL ES 2, GL3+, DX11) need to override this function to return the default material scheme of the RTSS ShaderGenerator.

This is currently only used to set the default material scheme for viewports. It is a necessary step on these render systems for render textures to be rendered into properly.

## _getFaceCount()

virtual unsigned int Ogre::RenderSystem::_getFaceCount | ( | void |  | ) | const

virtual

Reports the number of tris rendered since the last _beginGeometryCount call.

Returns
  A pointer to the automatically created window, if requested, otherwise null.

## _initRenderTargets()

virtual void Ogre::RenderSystem::_initRenderTargets | ( | void |  | ) |

Utility method for initialising all render targets attached to this rendering system.

## _makeOrthoMatrix()

virtual void Ogre::RenderSystem::_makeOrthoMatrix | ( | const Radian & | fovy,
|  | Real | aspect,
|  | Real | nearPlane,
|  | Real | farPlane,
|  | Matrix4 & | dest,
|  | bool | forGpuProgram = `false`
| ) |  |

pure virtual

Builds an orthographic projection matrix suitable for this render system.

Remarks
  Because different APIs have different requirements (some incompatible) for the projection matrix, this method allows each to implement their own correctly and pass back a generic OGRE matrix for storage in the engine.

## _makeProjectionMatrix() [1/2]

virtual void Ogre::RenderSystem::_makeProjectionMatrix | ( | const Radian & | fovy,
|  | Real | aspect,
|  | Real | nearPlane,
|  | Real | farPlane,
|  | Matrix4 & | dest,
|  | bool | forGpuProgram = `false`
| ) |  |

pure virtual

Builds a perspective projection matrix suitable for this render system.

Remarks
  Because different APIs have different requirements (some incompatible) for the projection matrix, this method allows each to implement their own correctly and pass back a generic OGRE matrix for storage in the engine.

## _makeProjectionMatrix() [2/2]

virtual void Ogre::RenderSystem::_makeProjectionMatrix | ( | Real | left,
|  | Real | right,
|  | Real | bottom,
|  | Real | top,
|  | Real | nearPlane,
|  | Real | farPlane,
|  | Matrix4 & | dest,
|  | bool | forGpuProgram = `false`
| ) |  |

pure virtual

Builds a perspective projection matrix for the case when frustum is not centered around camera.

Remarks
  Viewport coordinates are in camera coordinate frame, i.e. camera is at the origin.

## _notifyCameraRemoved()

virtual void Ogre::RenderSystem::_notifyCameraRemoved | ( | const Camera * | cam | ) |

virtual

Utility method to notify all render targets that a camera has been removed, in case they were referring to it as their viewer.

## _pauseFrame()

virtual RenderSystemContext* Ogre::RenderSystem::_pauseFrame | ( | void |  | ) |

virtual

Pause rendering for a frame.

This has to be called after _beginFrame and before _endFrame. Will usually be called by the SceneManager, don't use this manually unless you know what you are doing.

## _render()

virtual void Ogre::RenderSystem::_render | ( | const RenderOperation & | op | ) |

virtual

Render something to the active viewport.

Low-level rendering interface to perform rendering operations. Unlikely to be used directly by client applications, since the SceneManager and various support classes will be responsible for calling this method. Can only be called between _beginScene and _endScene

Parameters

  op | A rendering operation instance, which contains details of the operation to be performed.

## _resumeFrame()

virtual void Ogre::RenderSystem::_resumeFrame | ( | RenderSystemContext * | context | ) |

virtual

Resume rendering for a frame.

This has to be called after a _pauseFrame call Will usually be called by the SceneManager, don't use this manually unless you know what you are doing.

Parameters

  context | the render system context, as returned by _pauseFrame

## _setAlphaRejectSettings()

virtual void Ogre::RenderSystem::_setAlphaRejectSettings | ( | CompareFunction | func,
|  | unsigned char | value,
|  | bool | alphaToCoverage
| ) |  |

pure virtual

Sets the global alpha rejection approach for future renders.

By default images are rendered regardless of texture alpha. This method lets you change that.

Parameters

  func | The comparison function which must pass for a pixel to be written.
  value | The value to compare each pixels alpha value to (0-255)
  alphaToCoverage | Whether to enable alpha to coverage, if supported

## _setColourBufferWriteEnabled()

virtual void Ogre::RenderSystem::_setColourBufferWriteEnabled | ( | bool | red,
|  | bool | green,
|  | bool | blue,
|  | bool | alpha
| ) |  |

pure virtual

Sets whether or not colour buffer writing is enabled, and for which channels.

Remarks
  For some advanced effects, you may wish to turn off the writing of certain colour channels, or even all of the colour channels so that only the depth buffer is updated in a rendering pass. However, the chances are that you really want to use this option through the Material class.

Parameters

  red,green,blue,alpha | Whether writing is enabled for each of the 4 colour channels.

## _setCullingMode()

virtual void Ogre::RenderSystem::_setCullingMode | ( | CullingMode | mode | ) |

pure virtual

Sets the culling mode for the render system based on the 'vertex winding'.

A typical way for the rendering engine to cull triangles is based on the 'vertex winding' of triangles. Vertex winding refers to the direction in which the vertices are passed or indexed to in the rendering operation as viewed from the camera, and will wither be clockwise or anticlockwise (that's 'counterclockwise' for you Americans out there ;) The default is CULL_CLOCKWISE i.e. that only triangles whose vertices are passed/indexed in anticlockwise order are rendered - this is a common approach and is used in 3D studio models for example. You can alter this culling mode if you wish but it is not advised unless you know what you are doing. You may wish to use the CULL_NONE option for mesh data that you cull yourself where the vertex winding is uncertain.

## _setDepthBias()

virtual void Ogre::RenderSystem::_setDepthBias | ( | float | constantBias,
|  | float | slopeScaleBias = `0.0f`
| ) |  |

pure virtual

Sets the depth bias, NB you should use the Material version of this.

Remarks
  When polygons are coplanar, you can get problems with 'depth fighting' where the pixels from the two polys compete for the same screen pixel. This is particularly a problem for decals (polys attached to another surface to represent details such as bulletholes etc.).

  A way to combat this problem is to use a depth bias to adjust the depth buffer value used for the decal such that it is slightly higher than the true value, ensuring that the decal appears on top.

Note
  The final bias value is a combination of a constant bias and a bias proportional to the maximum depth slope of the polygon being rendered. The final bias is constantBias + slopeScaleBias * maxslope. Slope scale biasing is generally preferable but is not available on older hardware.

Parameters

  constantBias | The constant bias value, expressed as a value in homogeneous depth coordinates.
  slopeScaleBias | The bias value which is factored by the maximum slope of the polygon, see the description above. This is not supported by all cards.

## _setDepthBufferCheckEnabled()

virtual void Ogre::RenderSystem::_setDepthBufferCheckEnabled | ( | bool | enabled = `true` | ) |

pure virtual

Sets whether or not the depth buffer check is performed before a pixel write.

Parameters

  enabled | If true, the depth buffer is tested for each pixel and the frame buffer is only updated if the depth function test succeeds. If false, no test is performed and pixels are always written.

## _setDepthBufferFunction()

virtual void Ogre::RenderSystem::_setDepthBufferFunction | ( | CompareFunction | func = `CMPF_LESS_EQUAL` | ) |

pure virtual

Sets the comparison function for the depth buffer check.

Advanced use only - allows you to choose the function applied to compare the depth values of new and existing pixels in the depth buffer. Only an issue if the deoth buffer check is enabled (see _setDepthBufferCheckEnabled)

Parameters

  func | The comparison between the new depth and the existing depth which must return true for the new pixel to be written.

## _setDepthBufferParams()

virtual void Ogre::RenderSystem::_setDepthBufferParams | ( | bool | depthTest = `true`,
|  | bool | depthWrite = `true`,
|  | CompareFunction | depthFunction = `CMPF_LESS_EQUAL`
| ) |  |

pure virtual

Sets the mode of operation for depth buffer tests from this point onwards.

Sometimes you may wish to alter the behaviour of the depth buffer to achieve special effects. Because it's unlikely that you'll set these options for an entire frame, but rather use them to tweak settings between rendering objects, this is an internal method (indicated by the '_' prefix) which will be used by a SceneManager implementation rather than directly from the client application. If this method is never called the settings are automatically the same as the default parameters.

Parameters

  depthTest | If true, the depth buffer is tested for each pixel and the frame buffer is only updated if the depth function test succeeds. If false, no test is performed and pixels are always written.
  depthWrite | If true, the depth buffer is updated with the depth of the new pixel if the depth test succeeds. If false, the depth buffer is left unchanged even if a new pixel is written.
  depthFunction | Sets the function required for the depth test.

## _setDepthBufferWriteEnabled()

virtual void Ogre::RenderSystem::_setDepthBufferWriteEnabled | ( | bool | enabled = `true` | ) |

pure virtual

Sets whether or not the depth buffer is updated after a pixel write.

Parameters

  enabled | If true, the depth buffer is updated with the depth of the new pixel if the depth test succeeds. If false, the depth buffer is left unchanged even if a new pixel is written.

## _setFog()

virtual void Ogre::RenderSystem::_setFog | ( | FogMode | mode = `FOG_NONE`,
|  | const ColourValue & | colour = `ColourValue::White`,
|  | Real | expDensity = `1.0`,
|  | Real | linearStart = `0.0`,
|  | Real | linearEnd = `1.0`
| ) |  |

pure virtual

Sets the fogging mode for future geometry.

Parameters

  mode | Set up the mode of fog as described in the FogMode enum, or set to FOG_NONE to turn off.
  colour | The colour of the fog. Either set this to the same as your viewport background colour, or to blend in with a skydome or skybox.
  expDensity | The density of the fog in FOG_EXP or FOG_EXP2 mode, as a value between 0 and 1. The default is 1. i.e. completely opaque, lower values can mean that fog never completely obscures the scene.
  linearStart | Distance at which linear fog starts to encroach. The distance must be passed as a parametric value between 0 and 1, with 0 being the near clipping plane, and 1 being the far clipping plane. Only applicable if mode is FOG_LINEAR.
  linearEnd | Distance at which linear fog becomes completely opaque.The distance must be passed as a parametric value between 0 and 1, with 0 being the near clipping plane, and 1 being the far clipping plane. Only applicable if mode is FOG_LINEAR.

## _setPointParameters()

virtual void Ogre::RenderSystem::_setPointParameters | ( | Real | size,
|  | bool | attenuationEnabled,
|  | Real | constant,
|  | Real | linear,
|  | Real | quadratic,
|  | Real | minSize,
|  | Real | maxSize
| ) |  |

pure virtual

Sets the size of points and how they are attenuated with distance.

Remarks
  When performing point rendering or point sprite rendering, point size can be attenuated with distance. The equation for doing this is attenuation = 1 / (constant + linear * dist + quadratic * d^2) .

  For example, to disable distance attenuation (constant screensize) you would set constant to 1, and linear and quadratic to 0. A standard perspective attenuation would be 0, 1, 0 respectively.

## _setPointSpritesEnabled()

virtual void Ogre::RenderSystem::_setPointSpritesEnabled | ( | bool | enabled | ) |

pure virtual

Sets whether or not rendering points using OT_POINT_LIST will render point sprites (textured quads) or plain points.

|  | SceneBlendFactor | destFactor,
|  | SceneBlendOperation | op = `SBO_ADD`
| ) |  |

pure virtual

Sets the global blending factors for combining subsequent renders with the existing frame contents.

The result of the blending operation is:

final = (texture * sourceFactor) + (pixel * destFactor)

Each of the factors is specified as one of a number of options, as specified in the SceneBlendFactor enumerated type. By changing the operation you can change addition between the source and destination pixels to a different operator.

Parameters

  sourceFactor | The source factor in the above calculation, i.e. multiplied by the texture colour components.
  destFactor | The destination factor in the above calculation, i.e. multiplied by the pixel colour components.
  op | The blend operation mode for combining pixels

## _setSeparateSceneBlending()

virtual void Ogre::RenderSystem::_setSeparateSceneBlending | ( | SceneBlendFactor | sourceFactor,
|  | SceneBlendFactor | destFactor,
|  | SceneBlendFactor | sourceFactorAlpha,

|  | SceneBlendOperation | op = `SBO_ADD`,
|  | SceneBlendOperation | alphaOp = `SBO_ADD`
| ) |  |

pure virtual

Sets the global blending factors for combining subsequent renders with the existing frame contents.

The result of the blending operation is:

final = (texture * sourceFactor) + (pixel * destFactor)

Each of the factors is specified as one of a number of options, as specified in the SceneBlendFactor enumerated type.

Parameters

  sourceFactor | The source factor in the above calculation, i.e. multiplied by the texture colour components.
  destFactor | The destination factor in the above calculation, i.e. multiplied by the pixel colour components.

  alphaOp | The blend operation mode for combining pixel alpha values

## _setSurfaceParams()

virtual void Ogre::RenderSystem::_setSurfaceParams | ( | const ColourValue & | ambient,
|  | const ColourValue & | diffuse,
|  | const ColourValue & | specular,
|  | const ColourValue & | emissive,
|  | Real | shininess,
|  | TrackVertexColourType | tracking = `TVC_NONE`
| ) |  |

pure virtual

Sets the surface properties to be used for future rendering.

This method sets the the properties of the surfaces of objects to be rendered after it. In this context these surface properties are the amount of each type of light the object reflects (determining it's colour under different types of light), whether it emits light itself, and how shiny it is. Textures are not dealt with here, see the _setTetxure method for details. This method is used by _setMaterial so does not need to be called direct if that method is being used.

Parameters

  ambient | The amount of ambient (sourceless and directionless) light an object reflects. Affected by the colour/amount of ambient light in the scene.
  diffuse | The amount of light from directed sources that is reflected (affected by colour/amount of point, directed and spot light sources)
  specular | The amount of specular light reflected. This is also affected by directed light sources but represents the colour at the highlights of the object.
  emissive | The colour of light emitted from the object. Note that this will make an object seem brighter and not dependent on lights in the scene, but it will not act as a light, so will not illuminate other objects. Use a light attached to the same SceneNode as the object for this purpose.
  shininess | A value which only has an effect on specular highlights (so specular must be non-black). The higher this value, the smaller and crisper the specular highlights will be, imitating a more highly polished surface. This value is not constrained to 0.0-1.0, in fact it is likely to be more (10.0 gives a modest sheen to an object).

  tracking

  A bit field that describes which of the ambient, diffuse, specular and emissive colours follow the vertex colour of the primitive. When a bit in this field is set its ColourValue is ignored. This is a combination of TVC_AMBIENT, TVC_DIFFUSE, TVC_SPECULAR(note that the shininess value is still taken from shininess) and TVC_EMISSIVE. TVC_NONE means that there will be no material property tracking the vertex colours.

## _setTexture() [1/2]

|  | const TexturePtr & | texPtr
| ) |  |

pure virtual

|  | const LayerBlendModeEx & | bm
| ) |  |

pure virtual

Sets the texture blend modes from a TextureUnitState record.

virtual void Ogre::RenderSystem::_setTextureCoordSet | ( | size_t | unit,
|  | size_t | index
| ) |  |

pure virtual

Sets the texture coordinate set to use for a texture unit.

Meant for use internally - not generally used directly by apps - the Material and TextureUnitState classes let you manage textures far more easily.

Parameters

virtual void Ogre::RenderSystem::_setTextureMipmapBias | ( | size_t | unit,
|  | float | bias
| ) |  |

pure virtual

Sets the mipmap bias value for a given texture unit.

Remarks
  This allows you to adjust the mipmap calculation up or down for a given texture unit. Negative values force a larger mipmap to be used, positive values force a smaller mipmap to be used. Units are in numbers of levels, so +1 forces the mipmaps to one smaller level.

Note
  Only does something if render system has capability RSC_MIPMAP_LOD_BIAS.

virtual void Ogre::RenderSystem::_setTextureProjectionRelativeTo | ( | bool | enabled,
|  | const Vector3 & | pos
| ) |  |

virtual

Notify the rendersystem that it should adjust texture projection to be relative to a different origin.

|  | FilterType | ftype,
|  | FilterOptions | filter
| ) |  |

pure virtual

Sets a single filter for a given texture unit.

Parameters

  filter | The filter to be used

## _setTextureUnitSettings()

virtual void Ogre::RenderSystem::_setTextureUnitSettings | ( | size_t | texUnit,
|  | TextureUnitState & | tl
| ) |  |

virtual

Utility function for setting all the properties of a texture unit at once.

This method is also worth using over the individual texture unit settings because it only sets those settings which are different from the current settings for this unit, thus minimising render state changes.

## _setVertexTexture()

virtual void Ogre::RenderSystem::_setVertexTexture | ( | size_t | unit,
|  | const TexturePtr & | tex
| ) |  |

virtual

Binds a texture to a vertex sampler.

Remarks
  Not all rendersystems support separate vertex samplers. For those that do, you can set a texture for them, separate to the regular texture samplers, using this method. For those that don't, you should use the regular texture samplers which are shared between the vertex and fragment units; calling this method will throw an exception.

## _setViewMatrix()

virtual void Ogre::RenderSystem::_setViewMatrix | ( | const Matrix4 & | m | ) |

pure virtual

Sets the view transform matrix.

## _setViewport()

## addListener()

virtual void Ogre::RenderSystem::addListener | ( | Listener * | l | ) |

virtual

Adds a listener to the custom events that this render system can raise.

Remarks
  Some render systems have quite specific, internally generated events that the application may wish to be notified of. Many applications don't have to worry about these events, and can just trust OGRE to handle them, but if you want to know, you can add a listener here.

  Events are raised very generically by string name. Perhaps the most common example of a render system specific event is the loss and restoration of a device in DirectX; which OGRE deals with, but you may wish to know when it happens.

## getConfigOptions()

virtual ConfigOptionMap& Ogre::RenderSystem::getConfigOptions | ( | void |  | ) |

pure virtual

Returns the details of this API's configuration options.

Remarks
  Each render system must be able to inform the world of what options must/can be specified for it's operation.

  These are passed as strings for portability, but grouped into a structure (_ConfigOption) which includes both options and current value.

  Note that the settings returned from this call are affected by the options that have been set so far, since some options are interdependent.

## getHorizontalTexelOffset()

virtual Real Ogre::RenderSystem::getHorizontalTexelOffset | ( | void |  | ) |

pure virtual

Returns the horizontal texel offset value required for mapping texel origins to pixel origins in this rendersystem.

Remarks
  Since rendersystems sometimes disagree on the origin of a texel, mapping from texels to pixels can sometimes be problematic to implement generically. This method allows you to retrieve the offset required to map the origin of a texel to the origin of a pixel in the horizontal direction.

## getInvertVertexWinding()

virtual bool Ogre::RenderSystem::getInvertVertexWinding | ( | void |  | ) | const

## getMutableCapabilities()

RenderSystemCapabilities* Ogre::RenderSystem::getMutableCapabilities | ( |  | ) |

Get a pointer to the current capabilities being used by the RenderSystem.

Remarks
  The capabilities may be modified using this pointer, this will only have an effect before the RenderSystem has been initialised. It's intended use is to allow a listener of the RenderSystemCapabilitiesCreated event to customise the capabilities on the fly before the RenderSystem is initialised.

## getVerticalTexelOffset()

virtual Real Ogre::RenderSystem::getVerticalTexelOffset | ( | void |  | ) |

pure virtual

Returns the vertical texel offset value required for mapping texel origins to pixel origins in this rendersystem.

Remarks
  Since rendersystems sometimes disagree on the origin of a texel, mapping from texels to pixels can sometimes be problematic to implement generically. This method allows you to retrieve the offset required to map the origin of a texel to the origin of a pixel in the vertical direction.

## getWBufferEnabled()

bool Ogre::RenderSystem::getWBufferEnabled | ( | void |  | ) | const

## postExtraThreadsStarted()

virtual void Ogre::RenderSystem::postExtraThreadsStarted | ( |  | ) |

pure virtual

## preExtraThreadsStarted()

virtual void Ogre::RenderSystem::preExtraThreadsStarted | ( |  | ) |

pure virtual

Tell the rendersystem to perform any prep tasks it needs to directly before other threads which might access the rendering API are registered.

Remarks
  Call this from your main thread before starting your other threads (which themselves should call registerThread()). Note that if you start your own threads, there is a specific startup sequence which must be respected and requires synchronisation between the threads:
  1. [Main thread]Call preExtraThreadsStarted
  2. [Main thread]Start other thread, wait
  3. [Other thread]Call registerThread, notify main thread & continue
  4. [Main thread]Wake up & call postExtraThreadsStarted
  Once this init sequence is completed the threads are independent but this startup sequence must be respected.

## registerThread()

virtual void Ogre::RenderSystem::registerThread | ( |  | ) |

pure virtual

Register the an additional thread which may make calls to rendersystem-related objects.

Remarks
  This method should only be called by additional threads during their initialisation. If they intend to use hardware rendering system resources they should call this method before doing anything related to the render system. Some rendering APIs require a per-thread setup and this method will sort that out. It is also necessary to call unregisterThread before the thread shuts down.

Note
  This method takes no parameters - it must be called from the thread being registered and that context is enough.

## reinitialise()

virtual void Ogre::RenderSystem::reinitialise | ( | void |  | ) |

pure virtual

Restart the renderer (normally following a change in settings).

## removeListener()

virtual void Ogre::RenderSystem::removeListener | ( | Listener * | l | ) |

## setClipPlanesImpl()

virtual void Ogre::RenderSystem::setClipPlanesImpl | ( | const PlaneList & | clipPlanes | ) |

protected pure virtual

Internal method used to set the underlying clip planes when needed.

## setConfigOption()

virtual void Ogre::RenderSystem::setConfigOption | ( | const String & | name,
|  | const String & | value
| ) |  |

pure virtual

Sets an option for this API.

Remarks
  Used to confirm the settings (normally chosen by the user) in order to make the renderer able to initialise with the settings as required. This may be video mode, D3D driver, full screen / windowed etc. Called automatically by the default configuration dialog, and by the restoration of saved settings. These settings are stored and only activated when RenderSystem::initialise or RenderSystem::reinitialise are called.

  If using a custom configuration dialog, it is advised that the caller calls RenderSystem::getConfigOptions again, since some options can alter resulting from a selection.

Parameters

  name | The name of the option to alter.
  value | The value to set the option to.

## setCurrentPassIterationCount()

virtual void Ogre::RenderSystem::setCurrentPassIterationCount | ( | const size_t | count | ) |

virtual

set the current multi pass count value.

This must be set prior to calling _render() if multiple renderings of the same pass state are required.

Parameters

  count | Number of times to render the current state.

Definition at line 1365 of file OgreRenderSystem.h.

## setDepthBufferFor()

virtual void Ogre::RenderSystem::setDepthBufferFor | ( | RenderTarget * | renderTarget | ) |

virtual

Remarks
  RenderTarget's pool ID is respected.

See also
  RenderTarget::setDepthBufferPool()

## setDeriveDepthBias()

virtual void Ogre::RenderSystem::setDeriveDepthBias | ( | bool | derive,
|  | float | baseValue = `0.0f`,
|  | float | multiplier = `0.0f`,
|  | float | slopeScale = `0.0f`
| ) |  |

virtual

Tell the render system whether to derive a depth bias on its own based on the values passed to it in setCurrentPassIterationCount.

The depth bias set will be baseValue + iteration * multiplier

Parameters

  derive | True to tell the RS to derive this automatically
  baseValue | The base value to which the multiplier should be added
  multiplier | The amount of depth bias to apply per iteration
  slopeScale | The constant slope scale bias for completeness

Definition at line 1376 of file OgreRenderSystem.h.

## setLightingEnabled()

virtual void Ogre::RenderSystem::setLightingEnabled | ( | bool | enabled | ) |

pure virtual

Sets whether or not dynamic lighting is enabled.

Parameters

  enabled | If true, dynamic lighting is performed on geometry with normals supplied, geometry without normals will not be displayed. If false, no lighting is applied and all geometry will be full brightness.

## setNormaliseNormals()

virtual void Ogre::RenderSystem::setNormaliseNormals | ( | bool | normalise | ) |

pure virtual

Sets whether or not normals are to be automatically normalised.

Remarks
  This is useful when, for example, you are scaling SceneNodes such that normals may not be unit-length anymore. Note though that this has an overhead so should not be turn on unless you really need it.

  You should not normally call this direct unless you are rendering world geometry; set it on the Renderable because otherwise it will be overridden by material settings.

## setScissorTest()

virtual void Ogre::RenderSystem::setScissorTest | ( | bool | enabled,
|  | size_t | left = `0`,
|  | size_t | top = `0`,
|  | size_t | right = `800`,
|  | size_t | bottom = `600`
| ) |  |

pure virtual

Sets the 'scissor region' i.e.

the region of the target in which rendering can take place.

Remarks
  This method allows you to 'mask off' rendering in all but a given rectangular area as identified by the parameters to this method.

Note
  Not all systems support this method. Check the RenderSystemCapabilities for the RSC_SCISSOR_TEST capability to see if it is supported.

Parameters

  enabled | True to enable the scissor test, false to disable it.
  left,top,right,bottom | The location of the corners of the rectangle, expressed in pixels.

## setShadingType()

virtual void Ogre::RenderSystem::setShadingType | ( | ShadeOptions | so | ) |

pure virtual

Sets the type of light shading required (default = Gouraud).

## setStencilBufferParams()

virtual void Ogre::RenderSystem::setStencilBufferParams | ( | CompareFunction | func = `CMPF_ALWAYS_PASS`,
|  | uint32 | refValue = `0`,
|  | uint32 | compareMask = `0xFFFFFFFF`,
|  | uint32 | writeMask = `0xFFFFFFFF`,
|  | StencilOperation | stencilFailOp = `SOP_KEEP`,
|  | StencilOperation | depthFailOp = `SOP_KEEP`,
|  | StencilOperation | passOp = `SOP_KEEP`,
|  | bool | twoSidedOperation = `false`
| ) |  |

pure virtual

Determines if this system supports hardware accelerated stencil buffer.

Remarks
  Note that the lack of this function doesn't mean you can't do stencilling, but the stencilling operations will be provided in software, which will NOT be fast.

  Generally hardware stencils are only supported in 32-bit colour modes, because the stencil buffer shares the memory of the z-buffer, and in most cards the z-buffer has to be the same depth as the colour buffer. This means that in 32-bit mode, 24 bits of the z-buffer are depth and 8 bits are stencil. In 16-bit mode there is no room for a stencil (although some cards support a 15:1 depth:stencil option, this isn't useful for very much) so 8 bits of stencil are provided in software. This can mean that if you use stencilling, your applications may be faster in 32-but colour than in 16-bit, which may seem odd to some people. This method allows you to set all the stencil buffer parameters in one call.

Remarks
  The stencil buffer is used to mask out pixels in the render target, allowing you to do effects like mirrors, cut-outs, stencil shadows and more. Each of your batches of rendering is likely to ignore the stencil buffer, update it with new values, or apply it to mask the output of the render. The stencil test is:

      (Reference Value & Mask) CompareFunction (Stencil Buffer Value & Mask)

  The result of this will cause one of 3 actions depending on whether the test fails, succeeds but with the depth buffer check still failing, or succeeds with the depth buffer check passing too.

  Unlike other render states, stencilling is left for the application to turn on and off when it requires. This is because you are likely to want to change parameters between batches of arbitrary objects and control the ordering yourself. In order to batch things this way, you'll want to use OGRE's separate render queue groups (see RenderQueue) and register a RenderQueueListener to get notifications between batches.

  There are individual state change methods for each of the parameters set using this method. Note that the default values in this method represent the defaults at system start up too.

Parameters

  func | The comparison function applied.
  refValue | The reference value used in the comparison
  compareMask | The bitmask applied to both the stencil value and the reference value before comparison
  writeMask | The bitmask the controls which bits from refValue will be written to stencil buffer (valid for operations such as SOP_REPLACE). the stencil
  stencilFailOp | The action to perform when the stencil check fails
  depthFailOp | The action to perform when the stencil check passes, but the depth buffer check still fails
  passOp | The action to take when both the stencil and depth check pass.
  twoSidedOperation | If set to true, then if you render both back and front faces (you'll have to turn off culling) then these parameters will apply for front faces, and the inverse of them will happen for back faces (keep remains the same).

## setStencilCheckEnabled()

virtual void Ogre::RenderSystem::setStencilCheckEnabled | ( | bool | enabled | ) |

pure virtual

Turns stencil buffer checking on or off.

Remarks
  Stencilling (masking off areas of the rendering target based on the stencil buffer) can be turned on or off using this method. By default, stencilling is disabled.

Sets whether or not W-buffers are enabled if they are available for this renderer.

Parameters

  enabled | If true and the renderer supports them W-buffers will be used. If false W-buffers will not be used even if available. W-buffers are enabled by default for 16bit depth buffers and disabled for all other depths.

## shutdown()

virtual void Ogre::RenderSystem::shutdown | ( | void |  | ) |

virtual

Shutdown the renderer and cleanup resources.

## unbindGpuProgram()

virtual void Ogre::RenderSystem::unbindGpuProgram | ( | GpuProgramType | gptype | ) |

virtual

Unbinds GpuPrograms of a given GpuProgramType.

Remarks
  This returns the pipeline to fixed-function processing for this type.

## unregisterThread()

virtual void Ogre::RenderSystem::unregisterThread | ( |  | ) |

pure virtual

Unregister an additional thread which may make calls to rendersystem-related objects.

See also
  RenderSystem::registerThread

## updatePassIterationRenderState()

bool Ogre::RenderSystem::updatePassIterationRenderState | ( | void |  | ) |

protected

updates pass iteration rendering state including bound gpu program parameter pass iteration auto constant entry

Returns
  True if more iterations are required

## useCustomRenderSystemCapabilities()

virtual void Ogre::RenderSystem::useCustomRenderSystemCapabilities | ( | RenderSystemCapabilities * | capabilities | ) |

virtual

Force the render system to use the special capabilities.

Can only be called before the render system has been fully initializer (before createWindow is called)

Parameters

  capabilities | has to be a subset of the real capabilities and the caller is responsible for deallocating capabilities.

## validateConfigOptions()

virtual String Ogre::RenderSystem::validateConfigOptions | ( | void |  | ) |

pure virtual

Validates the options set for the rendering system, returning a message if there are problems.

Note
  If the returned string is empty, there are no problems.
