## Detailed Description

This is the target render state.

This class will hold the actual generated CPU/GPU programs. It will be initially build from the FFP state of a given Pass by the FFP builder and then will be linked with the custom pass render state and the global scheme render state. See ShaderGenerator::SGPass::buildTargetRenderState().

void Ogre::RTShader::TargetRenderState::link | ( | const RenderState & | other,
|  | Pass * | srcPass,
|  | Pass * | dstPass
| ) |  |

Link this target render state with the given render state.

Only sub render states with execution order that don't exist in this render state will be added.

Parameters:

  other | The other render state to append to this state.
  srcPass | The source pass that this render state is constructed from.
  dstPass | The destination pass that constructed from this render state.

Parameters:

  subRenderState | The sub render state to remove.

void Ogre::RTShader::RenderState::removeTemplateSubRenderState | ( | SubRenderState * | subRenderState | ) | `[inherited]`
