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

Recommended Posts

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.

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

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.
