#Cork-Screw animation
4 messages in this thread
I saw an animation at a fair, in which there was shown a cork-screw with
a square over it, moving from one side to the other. Within the square,
you could see a part of the cork-screw rendered as wire-frame. The part of
the cork-screw outside the square was rendered as phong.
Does anybody know how to realize this effect?
Holger:
That is an easy effect to create! Just render the entire cork-screw
animation in wire-frame first, then use it as an background. Now
create your box and give it a matt attribute and animate it wherever
you want to see the background. Now render the entire animation
again in phong, with the wire frame version as your background, and
wherever the matt object is located you will see through it to the
background!

Thanks a lot!!!

I could do it in TOPAS one pass, I think, or in 3DS VP in two passes
of rendering, once in wire frame, load as a bitmap background, then
render phong. I've done this in VP many times to create a wireframe
of objects to show "inner workings" of machinery. Kind of like X-ray
vision effect. JUst remember to turn on alpha to get it to work.
