about

nx_f32_voxel_gate.nx -- R4b/R4c: a PERSPECTIVE, TEXTURED, Z-BUFFERED procedural voxel LANDSCAPE on the sovereign hardware-f32 software path (NishiLang -> nx_cc_sovereign(f32) -> nxasm -> native ELF; NO gcc/GPU/ wasm/VM). Value-noise terrain, neighbour face-culling, height biomes (water/grass/stone/snow), directional shade, f32 mat4 camera + f32 perspective divide, per-pixel z-buffer, 24-bit BMP out. exit 0 = rendered. license_tier: ORIGINAL
