Public Member Functions
virtual GLint	GetVertexAttribIndexForSemantic (int semanticEnum)=0

Detailed Description

Abstract interface that is needed to tell the GlsGeometryResource which vertex attrib indices to use for a given rendering pass. (e.g. the attribute index to use can vary depending on the shader used).

Member Enumeration Documentation

AttributeSemanticEnum

enum AttributeSemanticEnum

The AttributeSemanticEnum enumeration. These are the predefined semantic values from the Cg language. Users should be able to define their own in the future, but these will be it for now.

Member Function Documentation

GetVertexAttribIndexForSemantic()

virtual GLint GetVertexAttribIndexForSemantic ( int  semanticEnum )

pure virtual

Returns

The attributeIndex that should be used to pass the vertex attributes or -1 if they are not needed (see glVertexAttrib)

Parameters

semanticEnum

The sematic value (see AttributeSemanticEnum)

Implemented in Effect_DiffNormSpecRefl, and Effect_DirectXShader.
