GR3EN: Generative Relighting for
3D Environments

Side by Side Relighting Visualization

Below we show side-by-side comparisons of input videos and our relighting results on scenes from the Eyeful Tower dataset. Drag the slider to compare.

Here we turn off the exterior light, turn off two of the three overhead lights, and turn on a yellow lamp on the table. Note how the reflections visible on the floor in the input video are not present in the output video.

Here we turn off the exterior light, and half of the overhead lights. Note the reflection of the exterior lights reflected in the glossy white wall, which is visible in the input video but is correctly removed in the output video. Also note how the window in the output video contains a reflection of the interior scene that was not visible in the input video.

Here we turn off the exterior light, turn on three of the six overhead lights and assign them with different colors. Note again the correct removal and inclusion of reflections, as well as global-illumination effects.

Here we turn off all overhead lights and insert a billboard-shaped neon light. Note that the reflection of the neon light appears on surfaces like windows, TV screens, and the table. Also note the cast shadows of objects on the table.
