Detailed Description

A single bind point for a vertex CgProgram.

This class manages a single binding point between a particular instance of a Cg vertex program fragment and remaps it to a logical VertexBindingType. The application must be able to provide the data that is needed for this bind point. For example the world*view*projection matrix.

See also:

enum VertexBindingType

Warning:

To minimize dependencies the internal bind point handle is case to a generic unsigned int

Member Function Documentation

bool CgVertexBind::Activate (  CgBinding *    bindings, unsigned int    program_handle, void *    context1, void *    context2 )

Passes the correct value down to the vertex shader program for a single dynamic bind point. The application provides the current valid data item for this binding type. If the application returns a null pointer then the value is not updated. Parameters: bindings  A pointer to the base class that contains the virtual methods we need to retrieve data from the application. program_handle  A handle to the CgShader program we are binding to. context1  An optional pointer provided by the application to help resolve any contextual requirements. context2  A second optional pointer provided by the application to resolve contextual requirements.
