My project is to display a rotating globe of the earth, with country borders, where the rotation is under mouse control. The globe will be about 500 pixels in diameter, with about 10K white pixel points for country borders, a blue circle, and a black background around the circle. I am not sure, but I may want to run this under windows 3.0. Also, I may want to use the IIT-3C87 chip on my 386 25mhz machine. This chip has 4X4 hardware matrix transformation capabilities. UR/FORTH seems like a good candidate language for this application, but I have no feel for how fast its graphics are, or if it will run with windows (although this may not be a requirement). I need to calculate about 30 frames/second for a smooth looking rotation. Does anyone have a feel if this would be possible with FORTH on my machine? Does any FORTH wordset exist that drives the IIT chip for matrix transformations? I'd appreciate any advice about this. Please email to ark2!rvp. Thanks!
