Detailed Description

This class declares the usage of a single vertex buffer as a component of a complete VertexDeclaration.

Remarks: Several vertex buffers can be used to supply the input geometry for a rendering operation, and in each case a vertex buffer can be used in different ways for different operations; the buffer itself does not define the semantics (position, normal etc), the VertexElement class does.
