Dear Experts, I've got a set of 3D points, which result in a movie, the points describes two triangles, which are moving in 3D in time (frame). Now I needed to draw the "height" of the triangles, which lines shall intersect somewhere outside of the triangles. Now I konw, how to draw a line betweeen two points, but how do I "lengthten" them in one direction? I hope, I was clear so far :DDD Thanx, Daniel
