Short: display&save parametric surfaces Uploader: u2203 sparc0a cs uiuc edu Architecture: m68k-amigaos This is a tool I wrote to explore parametric surfaces of two parameters (u and v, hence the name). You give it the equations X(u,v),Y(u,v) and Z(u,v), and the limits and increments for u and v, and it computes and displays the surface described. You can then rotate and illuminate and render the surface in various ways. This section is all done w/ integer math, and is just about as near to realtime as its going to get--- typically <10 secs redisplay time for 10,000 verticies using the slowest display mode (the nebula mode or an edged solid mode) on a plain 7.14 MHz 68000 Amiga. And you can also save images of the surface, and (3-D MODELERS TAKE NOTE!) the surfaces themselves as TDDD 3-d objects. This one runs under 1.2 and 1.3 w/ arp, or under 2.04 without.
