Mesh simplification is one of the many new features in the latest LiquiGen 1.1 release, which includes a complete surface post-processing pipeline with dozens of tunable parameters: - Mesh Simplification: reduces the triangle count of the generated mesh while preserving its overall shape - Smooth SDF: averages the surface to remove bumps and noise, with reshaping, depth limiting, and velocity/vorticity/density masks - Curvature Flow (MCF): geometry-aware smoothing that targets noise while preserving flat areas, thin sheets, and fine strands, with much better volume preservation than plain smoothing - Reshape: dilate/erode and open/close operations to grow/shrink the surface and fill or remove small features - Smooth Mesh: vertex smoothing with two algorithms — Bilateral (preserves sharp edges like wave crests and splashes) and Weighted Laplacian (aggressively flattens bulk surfaces while particle density protects droplets) - Snap to Colliders: pulls mesh vertices onto nearby collider surfaces so liquid sits flush against solids (e.g. water against the inside of a glass), with configurable distance, iterations, and margin - Clipping: remove solid faces at liquid/collider boundaries, and clip the mesh against connected primitives or imported meshes via a new 'Clipping geometry' input - Adaptive particle radius and a minimum-neighbors filter to mesh generation, helping fill holes, stabilize isolated particles temporally, and cull stray floating droplets

Introducing VDBView - as a personal project I made this free, lightweight tool for viewing VDB files. Give it a try and let me know what you think! - real-time 3D viewport - muti-grid support (individual controls for density, temperature, etc.) - sequence caching for smooth playback / scrubbing - basic lighting and shading, including blackbody emission - screenshot / sequence rendering exports (PNG) with basic CLI support - cross-section slicing - velocity streamlines - level set surface rendering - standalone, easy install - download, unzip, double-click Download link in comments below 🧵 #VDB #OpenVDB #VFX #Nvidia #DellProMax
