Gaussian Physics

The gaussian kernels are the simulation particles. No mesh anywhere.
Each kernel carries a deformation gradient F, and its covariance is carried along with it — Σ′ = F Σ Fᵀ. That is why a squashed region renders as flattened kernels rather than as kernels that merely moved. Transfers are MLS-MPM; snow and sand get their behaviour from clamping the stretch, which is also what makes them stop holding their shape.
Independent implementation of the method described in PhysGaussian (arXiv 2311.12198). That repository ships no licence, so no code from it is used here, and the test objects are generated rather than downloaded. Runs entirely in your browser.
