ASWF Summer Learning Program
MPM Fluid
Ice cubes dropped into a glass of cola, simulated with the MPM solver in Houdini 21. The ice is a rigid body simulation that drives colliders for the liquid.
Techniques
- MPM solver in Houdini 21: a water-like liquid of about 72,000 particles at test resolution, running on the GPU
- RBD ice: cubes dropped with the rigid body solver into a concave glass collider, then used as animated colliders for the MPM liquid
- Containment: after the solve, an SDF mask removes any particle outside the glass, so impact debris never escapes
- Rendered with Karma and MaterialX in an ACES colour pipeline
