ray-casting:� The algorithm used for drawing oblique perspective views of 3D raster objects.� The ray-casting algorithm uses the surface layer to draws 3D images more quickly than the original algorithm used in 3D Group and 3D Simulation.� However, users are given an option to turn off the ray-casting algorithm because this algorithm does not handle well raster objects that are larger than the surface layer.
