CPU smooth mesher optimizations (560ms → 17ms): - VoxelData grid cache eliminates redundant readVoxel calls - Pre-cached 27 neighbor chunk pointers (readVoxelFast) - smoothNear dilation (8 lookups/cell instead of 56) - Early exit via containsSmooth flag on chunks - Thread-local scratch buffers (SmoothScratch ~600KB) - wi::jobsystem parallelization across all cores - Persistent staging vectors for upload TopingSystem optimizations (58ms → 6ms): - collectInstancesParallel() with per-chunk local vectors - Neighbor chunk pointer caching GPU compute Surface Nets (Phase 5.3): - Two-pass compute shader: centroid grid + emit with smooth normals - Pass 1 (voxelSmoothCentroidCS): computes centroids + solid flags for cells [-1..32], cross-chunk neighbor voxel reading - Pass 2 (voxelSmoothCS): reads ONLY from centroid grid, computes area-weighted smooth normals from 12 incident edges per vertex - Batched dispatch: all centroid passes then all emit passes with single UAV→SRV barrier (instead of 2 barriers per chunk) - Smooth chunk filtering: only dispatches chunks with containsSmooth - Centroid grid buffer dynamically sized per smooth chunk count - 1-frame readback delay with auto-redispatch on first frame |
