void ACG::SceneGraph::MeshNodeT< Mesh >::setHalfedgeTextcoordPropertyName ( std::string _halfedgeTextcoordPropertyName )

Set the name of the per face texture coordinate property.

template<class Mesh >

void ACG::SceneGraph::MeshNodeT< Mesh >::setIndexPropertyName ( std::string _indexPropertyName )

set the name of the property used for texture index specification

The given property name will define a texture index. This index is used to make a lookup in the texture correspondence map containing for each index the gluint for the texture to be used. A zero in the property means, that no texture will be bound for the face. If you define a non existing name here, texture switching will be disabled and it is assumed that a texture is bound already.

Todo:: Remove the external texture loading and do it here.

Setup a mapping between internal texture ids on the mesh and the ids for the loaded textures in opengl.

Parameters

_map	maps between an int index stored in the Mesh describing which texture to use for a face, and the GluInt name of the texture bound by the TextureNode. If such a map is not available ( =0 ), assume TextureNode has already bound a texture And render without switching textures
