Gurgen Aloian built a custom real-time collision system entirely within Blender's Geometry Nodes, without using Blender's built-in physics engine. The technique works by checking if a mesh is inside another, then displacing it outward based on the mean position of the outer shell using backfired normals. It runs interactively in real-time and was originally designed to simplify sculpting collisions during animation. Aloian plans to either release it as a product or publish a tutorial explaining the setup.
