Vellum 101 - Sphere Packing A Surface
Added 2021-05-13 08:41:36 +0000 UTCWe've been awed by Kohei Nawa's Pixcell artworks: http://kohei-nawa.net/works/pixcell - and of course we thought this would be a walk in the park to rebuild in Houdini. Of course it turned out there's slightly more to it than just using a scatter-SOP and point relax.
In this tutorial we'll use Vellum Grains to quickly pack a surface with spheres.

Thanks for this tutorial!! I am trying the setup and am bumping into one issue: How can I ensure that the bigger particles/grains will force the smaller ones outwards to the sides? The way it is set up now I end up with the result that the bigger grains are pushed upwards, creating a kind of pile, instead of what I would like which is as described having the biggest grains pushing the other grains more out of the way... Is there an easy way to ensure this?
