Punkratio turns voxels into the smallest crack-free triangle meshes possible, in a small fraction of a frame.
Naive meshing spends two triangles on every voxel face: 24 for this frame. A greedy mesher cuts that to 8, but only by leaving four t-junctions, and those open as cracks.
Close them and the greedy mesh grows to 12. Punkratio stays at 8 with no t-junctions, the minimum for a sealed surface.
Meshing each chunk on its own leaves t-junctions on the seams, and those show up as pinholes. Punkratio's chunks agree on every seam vertex.
The demo's gyroid labyrinth, shown here for one repeat of the pattern, folds through every voxel. Punkratio meshes the whole 32³ chunk in about 0.2 ms.
Criterion results on a MacBook Pro M4, native build, one thread. The checkerboard is the worst case: every other voxel is solid.
The mesher itself, running in your browser. It needs a browser with WebGPU.
Punkratio is a voxel mesher written in Rust by Aldo Stracquadanio. This page is a playground for it and a sample of the work.
