What's the best way to make 3d surface like a wafer biscuit?

[Masoud]

Hello;

I would like to make a wafer biscuit, so I'm looking for the best way to make 3d surfaces like the image below, in Houdini?

I tried volume VOP + noise + VDB, but creating a suitable noise to mimic surfaces like that, is very hard.

I would appreciate any ideas.

 

Thanks.

my solution + do search on odforce, you have example or? post your approach altso its fun

Hi Masoud,

of course any aspect of this needs refinement, but you could first warp the voxel position a little. Then ask whether it has roughly the same distance to two close-by points of a point cloud thus resulting in cell walls (read Voronoi).

You will need a lot of resolution to get thin walls. So it may be better to just do this inside a shader. Also you may want to look through "Anyone can cook" by Pixar: https://graphics.pixar.com/library/AnyoneCanCook/paper.pdf

Thanks everyone,

Awesome points. I'll post my approaches soon...

Hi "Konstantin",
Is it possible to do the same thing in a shader...?!

Sure, try feeding several voronoises into a volumeshader and make sure to increase the volume step rate in the render settings.

Most of those examples, could use more work; but they were good attempts.
