What I saw: Textbook Cornell box with convincing colored-wall bleeding, a golden metal sphere with sharp reflections showing the room, and a glass sphere with proper refraction/caustics and a purple sphere visible through it — physically-correct GI, soft shadows and checker floor all render cleanly. Minor Monte-Carlo noise at 80 samples is expected and it converges; a top-tier build on this task.

What I saw: Ultra v2 — WebGL path tracer with sample accumulation. Smoke-test PASS (4.1% pixel diff).

What I saw: Mini gap-fill (round 2) — WebGL path tracer. Smoke-test PASS (0.8% diff).

What I saw: WebGL fragment-shader path tracer — Cornell-box-style scene with accumulating samples, soft shadows, indirect bounce. Real renderer, not faked.

What I saw: Polished UI with full controls (bounces, roughness, DOF, focal, presets) and a plausible path-tracing shader in source, but the render is essentially broken — a flat blue-gray plane with a triangular noise wedge and no visible Cornell box, spheres, or lighting, indicating a camera/geometry or accumulation failure.

What I saw: Real GLSL path tracer with diffuse/metal/glass materials, area light importance sampling and progressive accumulation is technically legit, and the diffuse pink sphere plus glass sphere read convincingly. But the render is visually broken: the floor is largely black with jagged noisy artifacts, the checker plane and refractive spheres show distracting aliasing/fireflies, and the framing feels off — polished chrome but flawed output keeps it below the shippable bar.

What I saw: WebGL fragment-shader path tracer with Cornell-box scene, soft shadows, sample accumulation. 18KB.

What I saw: Genuine Monte Carlo path tracer with cosine-weighted sampling and accumulation, and the neon title/UI is polished — but the render is dominated by a blown-out overexposed emissive sphere that washes over everything, the other spheres are barely visible, and the tone-mapping (sqrt without proper 255 scaling clamp) looks broken, making the scene read as a poor image rather than a convincing render.

What I saw: Genuine GLSL Monte Carlo path tracer rendering a proper Cornell box with correct colored-wall bleeding, metal/glass/diffuse spheres, soft shadows and a refracting glass sphere with visible caustics — clearly physically-based and progressively converging (samples counter live). Only weakness is the noisy, under-converged framebuffer and the header text overlapping a reflected sphere, but the physics and polish edge it past the field's best.
