+--- Thread: Internal Collision Detection? (/thread-3133.html)
Internal Collision Detection? - Dave LeDev - 13-10-2021
I've not yet purchased to find out-- does this asset only support external collisions or can it also handle internal?
Example use cases:
- A creature trying to get out of a closed, deformable container
- Bubble Boy
- Realistic skin deformation caused by internals

What do you mean "internal" collisions? Do you mean self-collisions? (an object colliding with itself). If so, yes.
If you mean two-sided collisions, the answer is yes too. Obi is a particle-based engine, objects are approximated as ellipsoidal particles. You can make convex, concave, one-sided and two-sided objects, with support for self-collisions (an object colliding with itself) and inter-collisions (deformable objects colliding with each other).

I'm wanting to use both self-collisions and inter-collsions. I just wasn't sure if the particles used allowed empty space on the inside for proper simulation.
