Hi,

The attached demo was provoked by the people who went ga-ga when
they saw a puny triangle jerking around recently..

It is pretty crude, hastily cobbled together from shreds of code I
threw at you a year or two ago (but you wisely ignored it). It can
certainly be made a lot faster with just a bit more effort, but right
now I have no time to play with it.

Btw, you will need a reasonably fast machine for the demo. I get only
about 7 fps on my old 486 and about 50 fps on a 233 MHz PII. But you
can use it to map just about any polygon from within the texture
sequence on to just about any other polygon, as long as the number of
vertices is the same. The mapping routine itself is roughly linear at
the moment, but you can fetch my old scaling tools from the Archives
and replace it with anything you fancy. Enjoy the distortions!

I confidently expect it will be expropriated by someone by the time I
get back in early in July, but I would rather prefer to see the
critical bits converted to assembly by somebody who knows what s/he
is doing (Nick?). Then we can all have fun. cu later. jiri
