- I'm currently writting a final year assignment in computer graphics for
- my BSc Computer Science Degree. The assignment involves writting an interactive
- nouniform Bspline curve, creating and ajustment. Using control Points, this I
- can do I think.
-
- The problem is that one of the other requirements is to be abble to toggle the
- display of the convex hull on and off. As you will know as the points macking
- up the hull are a subset of those defining the cureve, and also in an unknown
- order. I've looked in several books for an algorithm and can't find any.
-
- Help! Please mail me any algorithm you know of ASAP.
-
- Thanks for you Help
