Slosh: cross-platform MPM GPU physics simulation

Running the examples

1. Download the Slang compiler libraries for your platform: https://github.com/shader-slang/slang/releases/tag/v2025.16
2. Unzip the downloaded directory, and use its path as value to the SLANG_DIR environment variable: SLANG_DIR=/path/to/slang. Note that the variable must point to the root of the slang installation (i.e. the directory that contains bin and lib).
3. For the 2D examples, run cargo run --release --example testbed2
4. For the 3D examples, run cargo run --release --example testbed3

Notable MPM use-cases

This gives some insights of some interesting usages of MPM (the Material Point Method) for deformable physics simulation. Note that it doesn’t imply that slosh currently implements these models:

• Animation: one very well-known usage of MPM is snow simulation by Pixar.
• Engineering: blast movement simulation (patented).
