nx_pets_voxel3d.nx

nx_pets_voxel3d.nx -- RUNG 2 of the Pixelmon-exceed ladder: TRUE 3D voxel terrain by composing the team's CERTIFIED 3D math + z-buffered rasterizer. Replaces the rung-1 2.5D raycaster columns with real perspective-projected, depth-occluded, directionally-lit cubes (Minecraft-class). Composes (parts-composition doctrine -- I author ONLY the mesh/scene glue, not the math/raster): nx_camera_q14 -- certified Q14 camera: perspective + yaw/pitch + mat4 mul + mat4*vec4. nx_raster_triangle -- certified z-buffered Pineda rasterizer; u32 RGBA framebuffer that is EXPLICITLY browser-ready (JS reads Uint32Array -> putImageData). The alpha channel is an ambient/light multiplier -> per-face directional light. (nx_voxel_mesh is still ABSENT per MINECRAFTCLONE_BITS_UP_GAPS Gap 8, so the cube-face meshing here is the composition glue = tutor tooling, per the game-spec authorship law.) Pipeline (the real hardware-up render path): world cube corner (Q14) -> MVP = P*V (certified mat4) -> clip (certified mat4*vec4) -> perspective divide -> integer screen x,y + depth w -> certified z-buffered triangle raster -> u32 framebuffer -> 24bpp BMP (last-mile image; the same framebuffer feeds the browser canvas in the delivery rung). BAKED gate (camera-independent correctness, no false green): z-occlusion (near tri hides far) + projection (in-front projects centered, behind-camera is rejected, off-axis projects off-centre) + scene-non-empty. Browser delivery of this exact framebuffer = the NAMED next rung. license_tier: ORIGINAL
