Position-Based Dynamics Implementation in Houdini Grain Solvers
Houdini’s Grain solver operates on Position-Based Dynamics (PBD) principles, which decouple collision resolution from velocity integration. Instead of calculating forces and accelerating particles, the solver directly modifies particle coordinates to satisfy spatial constraints, then reconstructs velocities from the resulting positional delta.
