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.

Member Function Documentation

virtual bool Ogre::RTShader::SubRenderState::addFunctionInvocations ( ProgramSet programSet)
protectedvirtual

Add function invocation that this sub render state requires.

Parameters
programSetcontainer 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.

Parameters
rhsthe 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
programSetcontainer 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
rhsthe source sub state to copy from.
virtual bool Ogre::RTShader::SubRenderState::preAddToRenderState ( const RenderState renderState,
Pass srcPass,
Pass dstPass 
)
inlinevirtual

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
renderStateThe target render state container this sub render state is about to be added.
srcPassThe source pass.
dstPassThe destination pass.

Definition at line 115 of file OgreShaderSubRenderState.h.

virtual bool Ogre::RTShader::SubRenderState::resolveDependencies ( ProgramSet programSet)
protectedvirtual

Resolve dependencies that this sub render state requires.

Parameters
programSetcontainer 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 bool Ogre::RTShader::SubRenderState::resolveParameters ( ProgramSet programSet)
protectedvirtual

Resolve parameters that this sub render state requires.

Parameters
programSetcontainer 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::updateGpuProgramsParams ( Renderable rend,
Pass pass,
const AutoParamDataSource source,
const LightList pLightList 
)
inlinevirtual

Update GPU programs parameters before a rendering operation occurs.

This method is called in the context of SceneManager::renderSingle object via the RenderObjectListener interface and lets this sub render state instance opportunity to update custom GPU program parameters before the rendering action occurs.

See also
RenderObjectListener::notifyRenderSingleObject.
Parameters
rendThe renderable that is about to be rendered.
passThe pass that used for this rendering.
sourceThe auto parameter source.
pLightListThe light list used in the current rendering context.
