public interface ILcd3DMesh
extends ILcdBounded

An ILcd3DMesh represents a 3D geometric object. The 3D geometry is represented as follows:

• vertices, normals, texture coordinates and vertex colors are stored in (conceptually) separate pools
• the object itself is built out of primitives (e.g. points, lines, triangles, fans, strips, ...)
• each primitive consists of one or more elements
• each element contains indices into each of the vertex attribute pools
