### #ActualBrentChua

Edit: Lol nevermind about this. This entire post in my 2nd message doesn't make any sense. I still also need help on this.

Also the createEquation() function just creates a plane equation from the three vertex positions.  This also confuses me as i'm assuming the first parameter is the target position, the 2nd parameter is the first point in plane, and the 3rd parameter is the 2nd position on the plane. If the first parameter always points at the center, (0.0f, 0.0f, 0.0f, 0.0f). If we would construct the frustum for the first thread group, wouldn't all the planes in the frustum be pointing in the center of the view(see attached picture)? It doesn't seem to make much sense...
