Question by ejhung · Apr 21, 2016 at 04:50 AM · webplayerprojectionmatrix

ProjectionMatrix & worldtoCameraMatrix calculation

Hey guys, got curious on projection and worldtoCamera matrices.

I know unity provides good function for converting world position to viewport point. But at this point, I do want to calculate it from very bottom.

Assume there are only two vectors provided which is the world position of Camera and GameObject. C(a,b,c,) : Camera's world position G(d,e,f,) : GameObject's world position

from these two information, how can I calculate projection matrix and worldtoCamera matrix?
