| (...) 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], (...)

Also, it would look better in L3P/POV-Ray because then (...) (26 years ago, 16-Apr-99, to lugnet.cad.dev)

If I.Z is between min(Jmn.Z) and max(Jmn.Z) then I lies within quad Q. If I.Z is (...) (26 years ago, 16-Apr-99, to lugnet.cad.dev)
