Detailed Description

template<class Mesh>
class ACG::DrawMeshT< Mesh >

Mesh Drawing Class.

This class creates a new mesh for efficient rendering based on an OpenMesh object. DrawMesh also supports optimized picking and toggling between vertex/halfedge/face normals and vertex/halfedge texcoords.

It is not recommended to use this class if the input mesh does not implement an OpenMesh kernel. Instead, MeshCompiler can be used directly to build the vertex and index buffer.
