getting vertex of current frustum

OpenGL OpenGL: Basic Coding

Hi,

I have calculate the six bound planes of the current frustm, but I want to get the 8 vertices that define the bounding box around it ?

How I can calculate?
thanks in avance!

Cant you iterate the planes and find intersections between three of the planes?

I.e solve the eqn system:

A1x + B1y + C1z + D1 = 0
A2x + B2y + C2z + D2 = 0
A3x + B3y + C3*z + D3 = 0

for x,y,z.
where An, Bn, Cn, Dn is the equation constants for plane n.

thank you very much

I try use the Gauss’s method in order to solve it.
