i'm studying for my final and faced a clipping problem, i tried to search over google and youtube but couldn't understand the method to solve it
this is the head of question:
- Run a test to show whether or not point p (0,1,1) is considered in or out of each of the following planes: and the following planes he asked for clipping ( c1,c2,near,far )
look at dot product of (a) shortest vector starting on the plane ending on point p and (b) the in vector for each plane. If its positive, the point is in. If negative, its out.
