bourrasque_v2
GPU-accelerated fluid and material solver (water, elastic, sand) with a Blender extension for artist integration.
3×3 GPU SVD validated to within 1.9·10⁻⁴ of NumPy on 5402 matrices · sand model validated by angle of repose (25°/35°/45°) · 184/185 tests passing (the last one is an interop test that skips cleanly when its 600 MB binary fixture hasn't been regenerated locally) · dam-break on a 128³ grid simulated up to 2.9 M particles per frame, mesh reconstructed on the fly by the solver's native Zhu-Bridson mesher (up to 3.2 M triangles/frame), ~7.6 s/frame for the full simulation + reconstruction + Cycles render pipeline.
