Anyone interested in client development?

If you know the order of the vertices you can just calculate your own normals (hint: you do!) which is what we do in azone for .map files.

I know how to calculate face normals, but I think the order of the vertices in the file is wrong. Half of the faces use clockwise order (first picture) while the other half use anti-clockwise order (second picture).

The reason I mentioned the normals is that, if all the normals were pointing in the right direction I could detect which faces have the wrong order and change it. Unfortunately it seems faces specified clockwise have wrong normals and vice versa.

My bad, I was looking at the faces from the wrong direction. Looks like they are all specified in clockwise order. Asking OpenGL to cull front faces did the trick. D'oh!
