In Part 1 we discussed the base technique for determining relative orientation. We used that to answer the first two questions: To find relative orientation of two points and two directed segments with a common end point. In Part 2 we answer the next two questions: Given two line segments p0p1 and p1p2, if we [...]

Computational Geometry (CG) deals with algorithms for solving geometric problems. It is used in computer graphics, robotics, computer aided design,statistics among others. A typical CG problem takes as input a set of geometric objects like a set of points, a set of line segments etc. The output is most commonly finding certain attributes of the [...]
