Giacomo Balma, Sr. FX Technical Artist at MPC, has created a position-based particle orientation dynamics algorithm that computes the orientation of a particle by considering the change in position of its local neighbors. It is fully implemented in OpenCL for Houdini SideFX Software DOPs and adds very little overhead to the simulation. Learn more and watch a video of it in action.
