Subject: Aw: [stella] Gyruss and Polar co-ords From: cybergoth@xxxxxxxx Date: Tue, 23 Oct 2001 13:37:08 +0200 (CEST) |
Hi Roger! I remember doing sort of a rotating starfield sometime ago. It displayed some thousand stars rotating around an origin, getting bigger and brighter as you'd fly towards them. It was one of my first ever C++ things I coded and of course I knew nothing about polar or cartesian coordinates then. (Don't know much more now) If I remember correct, all I was doing was adding/subtracting the values of a sine table from 0-90 to the X/Y coordinates of every star. There was some logic in it, to determine wether the value was signed or not, depending on the quadrant and some 1-X subtraction where the cosine was needed. The source is gone, but I still have the starfield.exe, if someone is interested. (My goal was to beat the crap out of the windows starfield screensaver, and I think my attempt quite succeeded back then :-)) I don't think my approach could do circles though, but for a (emerging) starfield only code it'd probably be a qicker solution.
