I would like to get (with a fast method) the points that limits the frustum (4 for the front near plan & 4 for the front far plan)
I just would like coordinates of these point with a few instructions.
I uses for the moment, the intersection plane from the planes got by multiplying projection & modelview matrix.
But I'm not enough good in maths to get a fast solution
Yes I need to learn
But If anyone got a simple solution....
