Build a view frustum from angles
- by MulletDevil
I have 4 angles, left, right, top & bottom. These angles are in degrees. They define the angle between the forward vector and the corresponding side. I am trying to use these to calculate the required values for Perseective Off Centre function found here http://docs.unity3d.com/Documentation/ScriptReference/Camera-projectionMatrix.html
I tried doing
(near plane-far plane) * Tan(angle)
But that didn't give the correct results.
