about

nx_pets3d_wasm.nx -- KEYSTONE sub-rung B4: a REAL orbitable voxel TERRAIN in-browser wasm (not a toy cube). Composes the HAL-free nx_render_core to render a 12x12 procedural voxel world: per-column height, height-coloured (water/grass/rock/snow), directional face light, solid columns drawn as boxes, z-buffered. gi_render(frame) orbits the camera around the world centre on a 16-step ring (the native renderer's proven turntable framing), so JS can drive it from input -> interactive. NO syscalls: i64 packed-u32-RGBA fb + zb at fixed offsets; sovereign Q14 sin/cos angle table (no JS trig). license_tier: ORIGINAL
