Yeah, thanks for the input Steve. I fully agree with your statement about to many features dooming a project. If I decide to add any claculations I will add them last and only after everything else is working. BTW I will have to have another read of you artical in C=Hacking, It will probably make more sense to me this time around. ----- Original Message ----- From: "Steve Judd" <firstname.lastname@example.org> To: <email@example.com> Sent: Thursday, November 04, 2004 3:37 AM Subject: Re: C64 GRAPHICS CARD > Hola Hatch, > > > What simple calculations would you suggest or do you think would be > > the most helpful in speeding up 3D? also if I go for a chunky display, > > My advice is: don't worry about the calculations.
