RadianceLab

An interactive CPU/GPU renderer for testing transport ideas inside a scene you can actually work in. Ten selectable modes, spectral and RGB transport, media, node editing and path inspection connect algorithm experiments to a carefully composed final image.

  1. ◇

    Build the scene

    Edit geometry, materials, emitters and media through visible objects and nodes.

  2. L

    Choose transport

    Compare established sampling methods with experimental photon-primitive estimators.

  3. ↔

    Expose the internals

    Inspect paths, photon supports, guiding fields and intermediate images.

  4. ◉

    Take the shot

    Walk into position, set focus and aperture, then progressively refine.

The same workspace supports an algorithm experiment, interactive scene authoring and a finished photograph.
