Houdini Tutorial: Packing Rigid Bodies In Vellum
Support us on Patreon: / entagma
Yes, we covered this in our “packing the Torus” tutorial (https://entagma.com/packing-the-torus/), however back then we didn’t have Vellum! You draw the conclusions yourself!
Seriously though, using vellum for rigid body intersection detection and resolution can be a neat trick when you’re depending on a unified simulation framework which also allows you to simulate soft bodies as well as grains and liquids.
