Default Constructor.
|
|
Destructor.
|
|
Update a perspective projection matrix to use 'oblique depth projection'.
|
|
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. |
|
The RenderSystem will keep a count of tris rendered, this resets the count.
|
|
Converts a uniform projection matrix to suitable for this render system.
|
|
Creates a new rendering window.
Key: "colourDepth" Description: Colour depth of the resulting rendering window; only applies if fullScreen is set. Values: 16 or 32 Default: desktop depth Notes: [W32 specific] Key: "left" Description: screen x coordinate from left Values: positive integers Default: 'center window on screen' Notes: Ignored in case of full screen Key: "top" Description: screen y coordinate from top Values: positive integers Default: 'center window on screen' Notes: Ignored in case of full screen Key: "depthBuffer" [DX9 specific] Description: Use depth buffer Values: false or true Default: true Key: "externalWindowHandle" [API specific] Description: External window handle, for embedding the OGRE context Values: positive integer for W32 (HWND handle) poslong:posint:poslong (display*:screen:windowHandle) or poslong:posint:poslong:poslong (display*:screen:windowHandle:XVisualInfo*) for GLX Default: 0 (None) Key: "externalGLControl" [Win32 OpenGL specific] Description: 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. The Ogre OpenGL context can be retrieved after Ogre initialisation by calling wglGetCurrentDC() and wglGetCurrentContext(). It is only used when the externalWindowHandle parameter is used. Values: true, false Default: false Key: "externalGLContext" [Win32 OpenGL specific] Description: Use an externally created GL context Values: <context as="" unsigned="" long=""> Default: 0 (create own context) Key: "parentWindowHandle" [API specific] Description: Parent window handle, for embedding the OGRE context Values: positive integer for W32 (HWND handle) poslong:posint:poslong for GLX (display*:screen:windowHandle) Default: 0 (None) Key: "FSAA" Description: Full screen antialiasing factor Values: 0,2,4,6,...

Turns off a texture unit.
|
|
Disables all texture units from the given unit upwards.
|

Ends rendering of a frame to the current viewport.
|
|
Reports the number of batches rendered since the last _beginGeometryCount call.
|
|
|
|
Reports the number of tris rendered since the last _beginGeometryCount call.
|
|
Reports the number of vertices passed to the renderer since the last _beginGeometryCount call.
|
|
Get the current active viewport for rendering.
|
|
Start up the renderer using the settings selected (Or the defaults if none have been selected).
|
|
Utility method for initialising all render targets attached to this rendering system.
|
|
Builds an orthographic projection matrix suitable for this render system.
|
|
Builds a perspective projection matrix for the case when frustum is not centered around camera.
|
|
Builds a perspective projection matrix suitable for this render system.
|
|
Utility method to notify all render targets that a camera has been removed, in case they were referring to it as their viewer.
|
|
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
|
|
Sets the global alpha rejection approach for future renders. By default images are rendered regardless of texture alpha. This method lets you change that.
|
|
Sets whether or not colour buffer writing is enabled, and for which channels.
|
|
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. |
|
Sets the depth bias, NB you should use the Material version of this.
|
|
Sets whether or not the depth buffer check is performed before a pixel write.
|
|
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)
|
|
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.
|
|
Sets whether or not the depth buffer is updated after a pixel write.
|
|
Sets the fogging mode for future geometry.
|
|

|
|
Sets how to rasterise triangles, as points, wireframe or solid polys.
|
|
Sets the projection transform matrix.
|
|
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.

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.
|
|
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.
|
|
Sets the texture to bind to a given texture unit. User processes would not normally call this direct unless rendering primitives themselves.

|
|

|
|

|
|
Sets a method for automatically calculating texture coordinates for a stage. Should not be used by apps - for use by Ogre only. |
|
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.

|
|
Sets a single filter for a given texture unit.
|
|
Sets the filtering options for a given texture unit.
|
|
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. |
|
Binds a texture to a vertex sampler.
|
|
Sets the view transform matrix.
|
|
Sets the provided viewport as the active one for future rendering operations. This viewport is aware of it's own camera and render target. Must be implemented by subclass.

|
Returns the name of the rendering system.
|
|
Gets a list of the rendersystem specific events that this rendersystem can raise.
Definition at line 1151 of file OgreRenderSystem.h. |
|
Returns a pointer to the render target with the passed name, or NULL if that render target cannot be found.
|
|
Returns a specialised MapIterator over all render targets attached to the RenderSystem.

|
|
Returns true if the system is synchronising frames with the monitor vertical blank.
|
|
Returns true if the renderer will try to use W-buffers when avalible.
