Problem / Unfinished:

• first method works by comparing Z angles, it will cause flickering problem when angle switch from 359d to 0d
• second method works by comparing directional vectors with a threshold value representing the FOV. It is still unfinished, every direction length should be equal to 1, and i don’t know how to do it. *problem was that I forgot to convert Euler to directional vector
• still needs to support render ratios & camera shift
• Overall working in XY plane won’t work, as looking down will not be accurate
• Overall working in 2D won’t work, as camera YRoll won’t be supported

Just comparing 3D direction seems to work fine? file available here

But that’s not a true frustrum

Who can do better?
