Typically, this is coded recursively the recursive implementation lends itself to efficient hardware implementation.

Typically, this is coded recursively the recursive implementation lends itself to efficient hardware implementation. This algorithm is actually quite general the clip region can be any convex polygon in 2D, or any convex polyhedron in 3D.
