about

nx_meshview_wasm.nx -- R3: the sovereign general-mesh renderer EMITTED to WASM (runs in ANY browser via OUR software rasterizer -- zero WebGL, zero NVIDIA, zero Emscripten). Composes the HAL-free nx_render_core (z-buffered Pineda raster + Q14 perspective/mat4/Bhaskara-trig) over a loaded vertex+index mesh held at fixed linear-memory offsets (the proven nx_pets3d_wasm/nx_wasmcube wasm memory model: NO sys_mmap -- wasm has no syscalls). The browser's ONLY job is to call mv_render(angle) and blit the framebuffer to a <canvas>; ALL transform/projection/rasterization is sovereign Nishi. Mirrors the native nx_meshrender logic so the wasm build is bit-faithful to native (proven by nx_meshview_wasm_gate via nx_wasm_vm). Compiles through the SOVEREIGN chain: nx_compile_wat -> nx_wat_compiler -> .wasm. license_tier: ORIGINAL
