I notice that some graphic programs (like Quake) rely upon the floating =
point hardware. Does anybody know why?
As far as I can see, graphic programs use two kinds of data:
1: A value describing the color of a pixel. Normally up to 24 bits, which= may be a length suitable for being moved by a floating point processor, but will= not be subject to FP computations.
2: Two or three integers indicating a point's coordinates in space. = Normally 16 bits should suffice, but in extreme cases 32 bits may be used.
So why use a FP processor? For integer computations on coordinates?
Or does anybody know about any real FP data?
