Detailed Description
Management of coarse meshes.
This container will render meshes with very low polygon count efficiently.
Coarse meshes are merged in render passes. They are inserted in the render pass depending there number of vertices, with a granularity (NL3D_COARSEMESH_VERTEXBUFFER_GRANULARITY).
If NL3D_COARSEMESH_VERTEXBUFFER_GRANULARITY is 8, all meshes with 1 to 7 vertices will be rendered at the same time using the same vertex buffer, the same material and the same matrix. Then, meshes with 8 to 15 vertices will be rendered at the same time. etc..
Vertices are softly transformed in world space at the "setMatrixMesh" call.
Vertices get a uniform color per instance at the "setColorMesh" call.
All coarse meshes must use a common vertex format. It is a pos + UV vertex format. (NL3D_COARSEMESH_VERTEX_FORMAT_EXPORT)
Internally the CCoarseMeshManager store meshes with pos + UV + color vertex format, to color instances (NL3D_COARSEMESH_VERTEX_FORMAT_MGR)
Coarse meshes must use indexed triangle primitive in a single render pass in a single matrix block.
All coarse meshes musts use a single material. It is a simple mapping with alpha test rendering and a common texture.
The coarse meshes must have been preprocessed to build the common texture and remap the UV mapping coordinates in the new common texture.
The manager must have been setuped with the common texture.
NB: the manager is not renderable, because CoarseMeshManager must be rendered at end of frame in a direct call by CRenderTrav::traverse(), after coarse mesh instances added/removed in
