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.
| 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. |

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 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.
| 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. |

pure virtualinherited |
Sets the 'scissor region' i.e.
the region of the target in which rendering can take place.
| 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. |
Implemented in Ogre::D3D11RenderSystem, Ogre::GLRenderSystem, Ogre::D3D9RenderSystem, Ogre::GL3PlusRenderSystem, and Ogre::GLES2RenderSystem.
|
pure virtualinherited |
Clears one or more frame buffers on the active render target.
| buffers | Combination of one or more elements of FrameBufferType denoting which buffers are to be cleared |
| colour | The colour to clear the colour buffer with, if enabled |
| depth | The value to initialise the depth buffer with, if enabled |
| stencil | The value to initialise the stencil buffer with, if enabled. |
Implemented in Ogre::D3D11RenderSystem, Ogre::GLRenderSystem, Ogre::D3D9RenderSystem, Ogre::GL3PlusRenderSystem, and Ogre::GLES2RenderSystem.
|
inlinevirtualinherited |
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.
| count | Number of times to render the current state. |
|
inlineinherited |
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
| 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 |
|
pure virtualinherited |
Set current render target to target, enabling its device context if needed.
Implemented in Ogre::GLRenderSystem, Ogre::D3D11RenderSystem, Ogre::GL3PlusRenderSystem, Ogre::GLES2RenderSystem, and Ogre::D3D9RenderSystem.
|
staticinherited |
Sets shared listener.
|
staticinherited |
Retrieve a pointer to the current shared render system listener.
|
inherited |
Adds a listener to the custom events that this render system can raise.
|
inherited |
Remove a listener to the custom events that this render system can raise.
|
inlineinherited |
Gets a list of the rendersystem specific events that this rendersystem can raise.
|
pure virtualinherited |
Tell the rendersystem to perform any prep tasks it needs to directly before other threads which might access the rendering API are registered.
Implemented in Ogre::D3D11RenderSystem, Ogre::D3D9RenderSystem, Ogre::GLRenderSystem, Ogre::GL3PlusRenderSystem, and Ogre::GLES2RenderSystem.
|
pure virtualinherited |
Tell the rendersystem to perform any tasks it needs to directly after other threads which might access the rendering API are registered.
Implemented in Ogre::D3D11RenderSystem, Ogre::D3D9RenderSystem, Ogre::GLRenderSystem, Ogre::GL3PlusRenderSystem, and Ogre::GLES2RenderSystem.
|
pure virtualinherited |
Register the an additional thread which may make calls to rendersystem-related objects.
Implemented in Ogre::D3D11RenderSystem, Ogre::D3D9RenderSystem, Ogre::GLRenderSystem, Ogre::GL3PlusRenderSystem, and Ogre::GLES2RenderSystem.
|
pure virtualinherited |
Unregister an additional thread which may make calls to rendersystem-related objects.
Implemented in Ogre::D3D11RenderSystem, Ogre::D3D9RenderSystem, Ogre::GLRenderSystem, Ogre::GL3PlusRenderSystem, and Ogre::GLES2RenderSystem.
|
pure virtualinherited |
Gets the number of display monitors.
Implemented in Ogre::D3D9RenderSystem, Ogre::GLRenderSystem, Ogre::D3D11RenderSystem, Ogre::GL3PlusRenderSystem, and Ogre::GLES2RenderSystem.
|
pure virtualinherited |
This marks the beginning of an event for GPU profiling.
Implemented in Ogre::D3D9RenderSystem, Ogre::GLRenderSystem, Ogre::D3D11RenderSystem, Ogre::GL3PlusRenderSystem, and Ogre::GLES2RenderSystem.
|
pure virtualinherited |
Ends the currently active GPU profiling event.
Implemented in Ogre::D3D9RenderSystem, Ogre::GLRenderSystem, Ogre::D3D11RenderSystem, Ogre::GL3PlusRenderSystem, and Ogre::GLES2RenderSystem.
|
pure virtualinherited |
Marks an instantaneous event for graphics profilers.
This is equivalent to calling

pure virtualinherited |
Determines if the system has anisotropic mip map filter support.
Implemented in Ogre::D3D9RenderSystem, Ogre::GLRenderSystem, Ogre::D3D11RenderSystem, Ogre::GL3PlusRenderSystem, and Ogre::GLES2RenderSystem.
|
virtualinherited |
Gets a custom (maybe platform-specific) attribute.
| name | The name of the attribute. |
| pData | Pointer to memory of the right kind of structure to receive the info. |
Reimplemented in Ogre::D3D11RenderSystem.
|
inlinevirtualinherited |
Sets the colour buffer that the render system will to draw.
If the render system implementation or configuration does not support a particular value, then false will be returned and the current colour buffer value will not be modified.
| colourBuffer | Specifies the colour buffer that will be drawn into. |
Reimplemented in Ogre::D3D9RenderSystem, and Ogre::D3D11RenderSystem.
