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
