Each kernel carries a deformation gradient <b>F</b>, and its covariance is
carried along with it — <b>Σ′ = F Σ Fᵀ</b>. 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
<a href="https://arxiv.org/abs/2311.12198" target="_blank" rel="noopener">PhysGaussian</a>
(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.<br>
