about

nx_tex_sample_gate.nx -- proves general UV-sampled TEXTURE MAPPING: nx_tex_sample bilinear 4-tap + wrap modes (clamp/repeat/mirror), the GLSL texture2D / HLSL Sample primitive, pure integer. Hand-computed KATs + a neg-control + an artifact. Refutes the graphics-census "texture mapping PARTIAL: no general UV-sampled textures". license_tier: ORIGINAL expect_exit: 0
