hey everyone
I have a question in vector math.
Alright I got a trapezium from intersecting a plane with a (quadratic)pyramid. Now I believe to remember from game programming that it is possible to translate the four points restricting this trapezium to the x1,x2 plane by multiplying those points (actually their position vectors) with a matrix...
well my questions:
1) Can this be done
2) How do I do it (get the matrix)

Thanks in advance
