GetTexturePoints()

virtual Vector* GetTexturePoints ( void  )

virtual

Gets the object's texture points

The DisplayObject then uses a projection to compute the texture coordinates from these points. The most common is a Planar mapping, but a few objects use other mappings (e.g. Spherical or Cylindrical).
