Hello,
If I have a rectangle facing the screen in my scene, how can I determine the four corners so that it fills the screen exactly? In other words I think I want the four points where the plane of this rectangle intersects the viewing frustum.
I have some code that finds the eight corners of the entire frustum, so I should be able to intersect those planes with my rectangle’s. But I was wondering if there is a simpler way, where I don’t have to go through the math to get the whole frustum.
Thanks
Bob
