about
nx_wasmvoxel.nx -- a VOXEL TERRAIN in the WASM/BROWSER memory model: an 8x8 heightmap (two procedural hills,
height-banded grass/rock/snow) of f32-projected voxel columns, painter-sorted far->near, integer-filled to a
fixed-offset framebuffer. Same sovereign chain as the cube (nx_compile_wat -> nx_wat_compiler -> .wasm). JS owns
trig + blits the fb to <canvas>; wasm owns the world + the hardware f32 math. license_tier: ORIGINAL
