Hi and a Happy New Year to all visitors of my homepage! 

I made some small changes to the software renderer which also affected the examples. Currently I'm trying to render a NFS3 level with my software renderer but I have problems with z-fighting and numeric precision which corrupts texture mapping which is especially noticeable when the viewer moves.

UPDATE: The perspective problems where indeed caused by a too low precision of 1/w. This problem and also the z-fighting could be resolved by simply applying a scaling matrix to the entire scene and setting the near/far planes of the view frustum from [2, 500] to [0.2, 50].
