Bela – Its certainly true on the ST. Ill let ya know if its also true on the Amiga when I have benchmarks to hand. I have a secret button I can press that turns on and off the hidden line removal on StarGlider. You can press it any time you want to see the effects. Dont konw if Ill leave this in, yet.. hehe! Oh, by the way… even though Amiga's blitter can draw lines 10 times faster than a Software routine….. it has to draw the entire line into each bitplane separately. Thus if you were drawing into 5 bitplanes, you would have to draw 5 lines!!!! On my ST linedraw subroutine, it draws into all bitplanes simultaneously with almost negligible overhead.. so the Blitter isn't THAT much faster at worst case! — Jez.
