//========= Copyright Valve Corporation, All rights reserved. ============//
//
// Purpose: This is an example of a material that modifies vertex data
// in the shader. NOTE: Every pass is given a clean set of vertex data.
// Modifications made in the first pass are *not* carried over to the next pass
// Modifications must take place during the DYNAMIC_STATE block.
// Use the function MeshBuilder() to build the mesh
//
// Also note: Using thie feature is *really expensive*! It makes a copy of
// the vertex data *per pass!* If you wish to modify vertex data to be used
// with all passes, your best bet is to construct a dynamic mesh instead.
