So, I can definitely figure this math out but I was looking to see if there is a quick trick anyone can think of to make a plane fit exactly into the camera's frustum. IE if I have a camera at (0,0,-10) and a view port that is 1:1 or even 1:1.5 ratio what size would a plane need to be to cover the whole viewport...  (I know I know simple math), I was hoping for a quick method if anyone has one though, no rush its not anything I actively need but would be useful for a side projects I am doing.
