about

nx_voxel_world.nx -- PARAMETERIZED sovereign 3D-world renderer: a game-SPEC (DATA) -> a rendered world. Style is a spec field, NOT a hardcode -- the engine is not locked to one look: SP_STYLE 0=realism (textured, smooth light), 1=toon (banded light + silhouette outline = anime/cel), 2=flat (untextured facets = artsy low-poly). Geometry here is voxel terrain, but the rasterizer (fill_ztex) draws arbitrary textured triangles, so other geometry (meshes/characters) plugs into the same path. Composes nx_f32_hw. license_tier: ORIGINAL
