Bubble Level with nCloth

It is relatively simple to implement a bubble style carpenter's level with nCloth.

It uses an implicit technique for the solve that is inherently stable. You might find the following a useful reference: images.autodesk.com/adsk/files/autodeskmaya_nucleus_whitepaper.pdf

Can someone tell what type of cloth model the maya Nucleus is based on? Is it a mass-spring model like that of Maya Classic Cloth and Syflex?

Yes, it would be pretty trivial to do with nParticles. Duncan

I think splitting the bubble can now be achieved in maya 2009s' nParticle Module. What do you think? :)

hey no more tutorials ...focus on product dev ;)

Hi Duncan! I can't wait to see what product developement you did! Thanks a lot for those tuts! jocelyn "Strob" Simard, Montreal.

Thanks for taking some time to show us more neat tricks! Can't wait to see what the new development brings us!

Tanks a lots I will probably will mix two methods together. For a closeup shot i will take modeled bubbles, particles for back.... Main practical usage is for soap foam, air in the bottle, air in hydro system, biomedical purposes.

Splitting would be very difficult with this method. There might be a clever trick that could work, for example simulating many combined cloth bubbles with some kind of downstream merge history and sticky constraints, however I would be surprised if it were practical. For splitting bubbles I would use particles. You could look at the water nCloth example on this blog and modify it to have negative gravity. That example uses nCloth with vertex collisions and no stretch to create colliding particles. This is piped into a particle system which renders the result as blobbies. A problem with using blobbies for bubbles is that they smoothy merge together, instead of packing together then suddenly merging in a pop(still a bit of a research problem). However I've seen pretty good bubbles using blobby rendering.

Is it possible to automatically split main bubble to many little ones?

Very nice. Thanks for another great tip. Hope you get some time off from working too much... : ) Btw; I liked the new movie player a lot! Beats quicktime by far...
