about

nx_trimesh.nx -- ★SOVEREIGN TRIANGLE-MESH RASTERIZER (operator 2026-07-10, frank feedback: "we just have circles, no triangle or other capabilities for shapes to make more and more real things"). Correct: everything so far is axis-aligned ELLIPSOIDS (smooth blobs) -- no flat faces, sharp edges, or arbitrary form. This adds the UNIVERSAL primitive: the TRIANGLE. A real integer rasterizer -- transform -> perspective project -> barycentric fill with a Z-BUFFER + flat per-face shading -> arbitrary polygon meshes with FLAT FACES and SHARP EDGES. Plus a primitive library (cube/tetra/octa/pyramid/prism/icosahedron/uv-sphere) and composition (build real things from many meshes). 100% integer, sovereign (own trig, own raster). license_tier: ORIGINAL
