| (...) Whenever you'd like. If you think it would help you focus, or help collect LDAO ideas, thoughts, and issues together, or give people a more open forum to talk about LDAO, (or all of the above), then it's yours for the asking.

| | | | | Re: Quad intersections
|
| (...) Here's what I use, it works for triangles but you can easily change it for a quad. The idea is to check the angles between the vectors formed by each vertex and the point you're testing. x,y,z: point p1,p2,p3: vertex (float[3]) double pa1[3], (...)

| Based on Dave's formulae, I have been able to calculate the intersection of a plane (given three points) and a line (given two points). How do I then determine whether the point of intersection falls within a quad (as in Dave's "exercise left for (...) (26 years ago, 16-Apr-99, to lugnet.cad.dev)

| Steve, Where are you on this one? I did part of it previously, but saw you were in progress on the part tracker. If you haven't done the sections I have done, I'd be happy to send you what I have (or vice-versa). -John Van (26 years ago, 16-Apr-99, to lugnet.cad.dev)
