Soft Contact Deformer for Houdini
This is a digital asset i developed in Houdini, based on pixar’s paper “Acting with contact in Ratatouille” to be found at graphics.pixar.com
It’s a geometry operator that simulates contact between a soft surface, e.g. a character with other objects. The area around the collision is deformed using an animator-controlled curve. It also supports history based effects so the deformation can be ’sticky’.
Here’s a quick demo
This is a more detailed explanation.
I had some problems with the sound recording in this one, volume is pretty low and i sound like an alien at some points… that’s not me, it’s the recording ;-)

are you going to post an OTL for this?
kodiakMarch 10, 2008
Cool stuff, thanks for sharing.
Here is the challenge: would be great to have two way interaction as well :)

wow this is a great tool! are u going to release the OTL?
Hey guys, thanks for your comments.
For those of you asking for the OTL, i might release it in the future, just give me some more time.
Two-way interaction is definitely something i want to look into!

Brilliant work! I’d love to see some character animation tests with this, not to mention have a look under the hood. Please let the community know via odforce or the SESI list if/when you decide to release the OTL.
Cheers

Hi Kai,
really nice one!
Would be interesting to add springs to get some jiggle and nonlinear motions when the deformed mesh returns to the original pose…
Schöne Grüße,
Kai

Very nice work!
Hi Kai, ;)
i was thinking about implementing this, no problem in houdini :) maybe a delay could be mapped to the falloff distance as well, so the spring effect progresses along the bulge area
gruss zurück,
Kai

Man, that is soo cool! Really awesome work
luigiMarch 14, 2008
Brilliant man, as allways :-)
keep the good working on!
Uber nice Kai! :)
I think it is time to get my hands on Houdini.

Awesome, dude! I’m glad you are showing us amazing stuff like that! :-)
Hej Kai;)
Sieht sehr interessant aus, aber kenn mich da ja nicht so aus….
Wunder mich nur warum man dich nicht mehr online sieht oder nichts von dir hört…
Meld dich mal, email haste ja!
Grüße aus Berlin, Mikosch

This is very nice - well done! Is this on the Exchange, by any chance?
Jae YooJuly 15, 2008
Nice.. Well done!. It this on the exchange ?
Yes, this is awesome. Waiting patiently to see the two way mesh deformation :) It would be great to model organic forms this way in real time…
Well written article.

Great work here Aearon. I was looking to do a similar deformer in maya but don’t know where to start. If you’re familiar with maya, then would a pointOnMeshInfo node along with a network of utility nodes yield me something similar? It would be great if you could share the houdini file sometime!
