I have a piece of code I need to debug. Basically it's a polygon
clipper.When I use The allegro Polygon3d routines and, let's say I have
a quad, if, after clipping, the resulted poly is not a quad anymore, the
polygon3d function will display a weird shape on screen (starting from
the upper left corner and continuing with the quad's normal vertices).
However if I use the polygon (2d) routine with it, it will work just
fine with the same coordinates! How is this possible? Should I assume 
there might be a bug in polygon3d or a bug in my clipping code?
