about
nx_meshview.nx -- look at an .nxmesh. The program emits NXMSH2 meshes and had NO WAY TO VIEW ONE,
which is exactly how a skull that renders as an egg passed a 6/6 gate: every tooth measured counts
and determinism, and nothing ever drew the thing.
Orthographic z-buffered triangle fill, flat-shaded off the stored per-triangle normal, three views
side by side (front / side / three-quarter) so a shape can be judged rather than described.
nx_meshview <in.nxmesh> <out.png> [layer] layer: -1 all (default), 0 skin, 1 muscle, 2 bone
license_tier: ORIGINAL expect_exit: 0 No hw writes (Rule 26).
