Needing A Pyroclastic Noise Function

Recommended Posts

Has anyone ever written a Pyroclastic noise function for Houdini.

I have a couple of students whom desperately need a pyroclastic noise function they can use to manipulate a particle network.

Looking to create realistic pyroclastic type explosions and need that rolling effect that is so characteristic of pyroclastics.

I don't know if it is a noise function you are after or the ability to _stick_ the noise to the geometry composing the effect then somehow rotating either the geometry or the space that the noise is using for that primitive.

What method are you using for the smoke effect? Spheres, sprites, volumes?
