Hey, I've come up with this idea for a lightning engine, and it's gonna be 1000 times faster than what we have but to do it I need to know how to draw a line from point A to point B

Does anyone have a good algorythm on this? The ones I have are either anti-aliased or "not complete" (eg.: most angles don't work - sorry Fox )

If it's faster than the standard "x=x+constant"-or-something method (which I can't find anywhere ) it would be better, but still, I'm really desperate so anything will have to do
