Short: display&save parametric surfaces
Uploader: u2203@sparc0a.cs.uiuc.edu
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.
