Here's the deal... I have a point and click interface that for a variety of reasons uses a raytrace method for detecting whether or not the user has clicked an object (in 3D space). Currently I have the ray-plane part working fine, and I simplified the process by projecting the poly that I'm checking for colision onto a 2D plane. My problem is that I can't find any clear information on testing to see if a 2D point lies in a 2D triangle. I've been trying an algorithm that does 3 line tests (checks to see what side of the line it's on) but currently I'm not having any luck. What I'm looking for is a practical example. ----------------------------- Mice are an excellent source of mice. Edited by - Jo on 10/7/00 10:26:19 PM

Once again I end up answering my own question. An article I found over at flipcode on colison detection ended up helping me out by linking to other pertinent articles.


Hopefully this post will help someone find what they''re looking for faster than I did.
