inspiring snow :)

i find this snow video very inspirative...

Saw this the other day - is amazing! Seems to be based on PIC methods (as is FLIP), so guess it could be possible to hack into Houdini?!

I would really like to know how to get close to that quality. There must be a similar method in Houdini but the video´s explanation threw me off more than anything

so guess it could be possible to hack into Houdini?!

From what I've been told you could get 90%+ of the way there, but without writing some custom nodes you couldn't get all the way.

Just seen that someone's done a similar sim in Blender ...

Need this kind of multiphysics/Lagoa tech in Houdini!!

[Annon]

If I remember correctly lagoa is based on spring constraints, this stuff is more like flip. From what I've been told what we need is to be able to look up how many points are in a grid voxel so you can maintain mass by adding/reaping points in a "cluster" as you need.

I'd love to get a bit of time to sit down and work out exactly how far we can get with the standard tools, but the chances of that at the minute are zero.

Yeah, the material-point-method used is a close relative to FLIP, and it should be possible to do in DOPs as is. The problem is their snow material model and implicit solver, which I very much doubt could be done with the existing microsolvers.

Isnt that exactly what the gas particle count DOP does.
