## Detailed Description

This class is the base interface of sub part from a shader based rendering pipeline.

All sub parts implementations should derive from it and implement the needed methods. A simple example of sub class of this interface will be the transform sub state of the fixed pipeline.

Add function invocation that this sub render state requires.

Parameters:

  programSet | container class of CPU and GPU programs that this sub state will affect on.

Remarks:
  Internal method called in the context of SubRenderState::createCpuSubPrograms implementation.

virtual void Ogre::RTShader::SubRenderState::copyFrom | ( | const SubRenderState & | rhs | ) | `[pure virtual]`

Copy details from a given sub render state to this one.

  rhs | the source sub state to copy from.

virtual bool Ogre::RTShader::SubRenderState::createCpuSubPrograms | ( | ProgramSet * | programSet | ) | `[virtual]`

Create sub programs that represents this sub render state as part of a program set.

The given program set contains CPU programs that represents a vertex shader and pixel shader. One should use these program class API to create a representation of the sub state he wished to implement.

Parameters:

  programSet | container class of CPU and GPU programs that this sub state will affect on.

SubRenderStateAccessorPtr Ogre::RTShader::SubRenderState::getAccessor | ( |  | ) |

Return the accessor object to this sub render state.

See also:
  SubRenderStateAccessor.

SubRenderStateAccessorPtr Ogre::RTShader::SubRenderState::getAccessor | ( |  | ) | const

Return the accessor object to this sub render state.

See also:
  SubRenderStateAccessor.

virtual int Ogre::RTShader::SubRenderState::getExecutionOrder | ( |  | ) | const`[pure virtual]`

Get the execution order of this sub render state.

Remarks:
  The return value should be synchronized with the predefined values of the FFPShaderStage enum.

virtual const String& Ogre::RTShader::SubRenderState::getType | ( |  | ) | const`[pure virtual]`

Get the type of this sub render state.

Remarks:
  The type string should be unique among all registered sub render states.

SubRenderState& Ogre::RTShader::SubRenderState::operator= | ( | const SubRenderState & | rhs | ) |

Operator = declaration.

Assign the given source sub state to this sub state.

Parameters:

  rhs | the source sub state to copy from.

virtual bool Ogre::RTShader::SubRenderState::preAddToRenderState | ( | const RenderState * | renderState,

| ) |  | `[virtual]`

Called before adding this sub render state to the given render state.

Allows this sub render state class to configure specific parameters depending on source pass or parent render state. Return of false value will cause canceling the add operation.

Parameters:
