Which of the following algorithm can be used to clip a polygon in 3D space? a) Weiler Atherton Algorithm b) Vatti Clipping Algorithm c) Greiner Hormann Clipping Algorithm d) Polygon in 3D space cannot be clipped
Answer: a Explanation: The algorithm that can be used in 3D space as well is Weiler Atherton Algorithm. It is mostly used in 2D space but can be used in 3D space with the help of Z-ordering. The Vatti Clipping algorithm and Greiner Hormann Clipping algorithm only works on 2D space.
