Help Simulating Toothpaste and Icing

[gmichaelcaputo]

Hi all, I'm considering purchasing Obi Fluid for the following scenario:

- User has a tube of toothpaste or icing in their hand
- On key press, the "fluid" starts coming out of the end of the tube
- Fluid behaves like real life, example:
   - Make a "dollop"

   - Make a coagulated zig-zag:

   - Fluid deforms if in contact with rigidbodies
   

Is that something that Obi Fluid could support? I have seen the honey simulation but this would be less viscous and more self-sticking.

Thanks,
Mike

Toothpaste is way, way more viscous than honey. So viscous in fact, it's almost semi-solid. High viscosity requires small time steps to maintain stability, so the higher the viscosity, the costlier it is to simulate. I'd say this range of viscosity cannot be simulated in realtime yet.

State-of-the-art offline simulators take hours to simulate something similar. See:
