Hello!

Does anybody of you have an idea how to project a 3D Object to a 2D Plain? My 3D Object consists of many tetraeders (with different colors) and therefore is a polyeder.

What I have is a polyeder that is in a XYZ coordinate system and that I want to project to a XY or YZ etc. plain (with the corresponding colors). I thought about drawing all triangles of the tetraeder of the polyeder in a certain row so that I finally have some kind of projection, but I dont know how I should sort the triangles before drawing them. Another but more complex idea is to find the collision point of a parallel ray (parallel to the not included Axis) with the polyeder - and project it to the corresponding plane, but honorly I have no idea how to realize it. Do you have any idea how to make it (if possible as easy as possible:)) - maybe you can give me a bit of a code? Thanx in advance,

Stefan
