Elastic band rig

Post by Zafar Iqbal » 01 Apr 2013, 11:19

I'm looking for someone who can solve a problem for me - I need it done fast and hopefully someone can jump on this quick.

Following image explains the basic idea:
Image

The band needs to be elastic so that I can stretch to whatever height/length.
The band needs to match the shape of whatever it is touching. The image shows a band wrapping a box and that's on the simpler end of the scale. The true challenge is to match the shape of something more complex - lets way an elephants back - an animated elephant on top of that.
The setup must be flexible enough to use in different scenarios.

Send me a PM along with few words about how you plan on solving this, how long it will take and your price.

I can provide more information in PM but by description pretty much sums it up.

I'm on SI 2013 and need this ASAP.

Thanks,
- Zafar Iqbal

So what was the solution, mind I ask?

It's in the works and I'm told it will be ICE related.

Let me guess - ICE Syflex or Bullet physics implementation?
$ifndef "Softimage"
set "Softimage" "true"
$endif

Or a simple raycast + manual offset controls as animation rig and a layer of simulation on top :)

Yes, pretty much something like that (and using Syflex). Not something I'd be able to come up with within a reasonable amount of time.

In the end Ice is used to calculate point positions with a basic raycast and interpolated arrays which then is used for a curve which is then simulated with syflex to achieve better collisions.

Real Mesh Collision Detection and Handling through Ice is still quite complex I guess and Syflex is the easier solution to handle this. Raycast didnt work for me for more or less a simple reason: in which direction u gonna cast the ray ?
