A little while ago, Vimeo user Andrew, and Tim van Helsdingen offered some insight into translating Houdini particle simulations into bullet simulations in the same scene. Working with Bullet sims again, Andrew revisits some older research of his which might have some new life, after learning some new tricks. It deals with VDB Fractures.
Andrew shows how he created a VDB Fracture that can be run through Bullet physics. VDB Fracture can cut up your geometry into natural looking and irregular pieces. VDB Fracture which can cut up your geometry into natural looking and irregular pieces, that can easily be run through a bullet simulation afterwards. The idea is to create Poly Fragments and packed spheres from the VDB stuff. Then it is a matter of a bit of Wrangle Code to link those two together.
