Hi,

I'm planning on using fixed point math for my 3d engine. (For those of you
ready to recommend floating point on the pentium of powerpc... I'm
targeting low end computers. No texture mapping, just flat-shaded
polygons.) Now, I'd like to find some info on problems and solutions
relating to using fixed instead of floating point. (The problems of
overflow, and that of numbers close to zero losing all precision comes to
mind). Source code would also help, I guess. I'd prefer online sources of
information (cheap) but if you know of any good books covering the subject
feel free to recommend them too!

Thanks!

-Patrik
