Ray cone intersection
Hi,
I'm trying to come up with a technique for determining whether a ray intersects a cone. The cone is truncated, i.e. one of the ends does not necessarily have a radius of zero, and the cone is not based at the origin.
I'm having real trouble with this at the moment because I've been unable to locate any really useful resources on the net and there aren't any similar topics on this forum. The best thing I've found so far is the following:
http://www.bmsc.washington.edu/people/me...drics.html
Which doesn't go into much detail. Can anyone please help?

The above link (formely Wild Magic) has a ton of source code for doing a variety of intersections, including line/code (to get raycone, do linecone first, and then find where on the line the intersection is.)
Here's how the algorithm works:
