Wouldn't you like to team-up and do all the 3D-Math stuff for my Star Fire project next year? (I'll probably have to take your code as a base anyway :-)) > The concept is proven in BASIC but converting > it to 6502 .asm is always fun... Hehe, in order to do Star Fire I started out doing QBASIC recently too. My intention was turning Steven Judds QBASIC version of his 'Polygamy' project into a 3D system that that calculates circles (Middle X/Y + Radius) only. I'd use that as 'Position + Size' for the Star Fire ships then. I just didn't have the time to dig to deep into that yet. Seems like you're way ahead currently! Cool stuff. I'll have a printout of your source as my weekend lecture, so I might comment on that next week.
