I'd like some hard data on the blitter vs. the CPU for polygon rendering..
I've heard people here assert that the CPU is faster, even on a 68000.

How much faster?  Are you using the blitter to copy the polygon into the
appropriate bitplanes once it is drawn, or are you using the processor to
fill the bitplanes in parallel?

I'm assuming you're using an ordered edge list?

Thanks for any elucidation..
