nx_pets_voxel_view.nx

nx_pets_voxel_view.nx -- RUNG 1 of the Pixelmon-exceed ladder: render the PETS world in first-person 3D by COMPOSING the team's CERTIFIED voxel renderer, not by re-authoring one. Composes (parts-composition doctrine, game_parts.tsv `render-input`): nx_raycast_voxel -- the certified DDA voxel ray-walk (Q14 fixed-point, no FPU; the "minecraft on lowest hardware" core). We do NOT reimplement DDA. nx_tissue -- the certified palette-packed 3D voxel store (the world container). What THIS organ authors (the composition glue = tutor tooling, per game-spec authorship law): - lift the pets 16x12 map into a tissue (walls/trees = solid voxels), - a camera-plane ray sweep (one ray per screen column) over the 4-direction facing the pets game already uses (free-look/trig = a LATER rung; this rung stays atomic), - perspective projection of wall slices. KEY: with a cardinal-facing camera the perpendicular distance to a hit is exactly (hit_axis - cam_axis) in voxels -> zero fisheye, zero fixed-point t-scaling ambiguity, - face + distance-fog shading, floor/sky split, - a viewable 24-bit BMP (last-mile image, same standing as the canvas framebuffer), - a BAKED pos/neg gate: HIT coords + perspective-monotonic + occlusion + face-shading, so the render capability self-proves (no false green). NO browser yet: in-browser 3D delivery is the NAMED next rung (wasm/stream surface = the MINECRAFTCLONE bits-up gap). Native-3D-now, browser-3D-next, no floating capability. license_tier: ORIGINAL
