I'm writing a 3d engine as a special project in school.
Therefore it is not very fast but rather easy to understand,
everything is class based and most of the stuff are done
automatacally. BUT.. I have two problems.. polygon sorting
and clipping. What I think I would need is a function that
converts a point from the standard plane to the camera
plane so I can calculate where the point is related to what
position the camera is. But, I have no idea how so currently
I'm sorting polygons by z and I have no clipping. So if you
could help me it would really be appreciated.
