◆ bindBufferVS()

virtual void Ogre::ConstBufferPacked::bindBufferVS ( uint16 slot )

pure virtual

Binds the constant buffer to the given slot in the Vertex/Pixel/Geometry/Hull/Domain/Compute Shader.

Remarks: Not all RS API separate by shader stage. For best compatibility, don't assign two different buffers at the same slot for different stages (just leave the slot empty on the stages you don't use).
