Culling is the process of removing objects which are not visible to the camera from the frame. Culling can also be used for removing a hidden surface in the graphics processor. Clipping is a process through which the polygons which extend past the camera are picked or culled. Culling leaves just a few polygons for Paper vision engines to process.
Clipping establishes the highest polygon when compared to culling. Most clipping methods are used than the culling technique. Clipping techniques are used when the objects are not really visible. By using the clipping technique, video quality is increased, and also the frame rate is better.
However, clipping would also increase the speed of presentation. Clipping is done before rasterization. Culling is done by application and also done before transformation and lighting. Most times, the clipping is done by the graphics system. Culling is also known to reject objects completely outside of the viewing volume.
