Custom Particle Collision

[JuriBryan]

Hey,

I was wondering if there is a way to give particles custom collision geometry.

I ran into some minor problems with some debri shots that I want to do, manly that the particles are not intersecting with the main RBD simulation at all(which is good)

but as soon as I instance my debri geometry on the points it intersects everywhere.

So I was wondering if there is a way to lets say instance the debri on the particles in a POP SOPs and use that geometry as a collision radius, which means that every particle has a different collision surface and would react different based on the edges of the instanced geometry.

I saw something like that with thinkingParticles and was wondering if there is something like that for Houdini.

Cheers,

Juri

If your particle count isn't crazy perhaps you could use bullet to simulate the particles?

[JuriBryan]

yea that is a possibility, I was just wondering if there is a way to set something like that up in Sops using a PoP network.

You can use an RBD Point Object in DOPs, it's one way to do what you're after, but it would involve using DOPs, which isn't the greatest.

You can use PC Open's search radius as a quick and dirty form of collision detection. Not perfect as it treats everything like a sphere but for debris you might be able to get away with it.

ok thanks everybody!

I will take a look into all of those things now:)

cheers
