Gosh, the one time I'm actually serious about a project, nobody else wants to
be <g>.
FWIW and FYI, I finally used a variation on Jack's suggestion to great effect.
I used a thin rectangle shape, lofted with twists in it and mapping
co-ordinates on. I then made 2 more of the same thing, except with the shape
rotated 90 degrees each time before lofting. I then bent all of the three
twisted objects and morphed between them. In this way I was able to get the
twist to travel along the path giving the appearance of pulsating fluid pouring
out of the beer bottle and arcing down into the glass. Add a beer material and
an animated opacity map and the pouring part was complete. I then had to add a
seperate piece of geometry for the contents of the bottle complete with
animated opacity map to represent the diminishment of the contents. The final
touch was a piece of geometry for the beer in the glass, part beer and part
froth, which scaled up to fill the straight glass. Timing all of these
happenings was the hardest part, but it all came together today and the client
loved it! The final rendered resolution was 320×200, <chuckle>, and there is a
quarter screen 160×100 version and it will probably appear at some or all Black
Angus restaurants and other Sports bars etc. as a quarter screen overlay to
football games and such like.
This project certainly tested my powers of animation problem-solving <g>.
