Hi!

I recall seeing a cg-animation on a tv show a couple of years ago; when 3d
computer animation was still a new and hot topic. It was a cylinder bending
over, finally touching the ground. I have used some time trying to recreate
that magic (!) moment, using triangle meshes, blobs, unions of cylinders
et.c., but none came as close as this. It contains some simple yet clever
(in my opinion) maths to create and animate the object, which is rather
simple.

The animation takes place in a not-too-interesting environment, (read: a
checkered plane), but the blurred reflection looks quite good reflecting a
well-defined pattern.

By the way: has anyone yet tried to animate blurred reflection? Is this the
first post of that kind?

I think this was enough rambling about such a simple animation.

Simen.

Simple yet very nicely done.  So what's this simple yet clever math that you
used to do this?
I bet you just used Chris Colefax's "BEND.INC" file didn't you?  :)

IMHO, it's a portion of torus, with major radius decreasing...
I've made a similar anim to test motion blur....

I'll bet he didn't... I think he sliced a torus while decreasing the major
radius and increasing the angle of the cut.

Really? Hit the nail on the head! But I still think it was clever, though...

I agree ;)

Looking thru the VFAQ, it is actually mentioned that this is a good
technique to do this; that is using a clipped torus (see replies). It seems
I'm not the only one who has seen that oldie anim!

Looks very convincing! May I see the code?
thanks,
