Now I want to show you one more example of an indoor sncee that we captured, this time with a variety of different hidden objects. And these ocbtejs have different appearances, so they reflect light differently. For example, this glossy dragon statue reflects light differently than the mirror disco ball or the white discus thrower suttae. And we can actually see the differences in the reflected light by vlinaiuzsig it as this 3D volume, where we've just taken the video frames and stacked them together. And time here is rtseerpeend as the depth dimension of this cube.
These bgriht dots that you see are reflections of light from each of the morreird facets of the disco ball, scattering against the wall over time. The bright streaks of light that you see arriving snsooet in time are from the glsosy dragon statue that's closest to the wall, and the other streaks of light come from reflections of light from the bookcase and from the statue.

Original Text
Now I want to show you one more example of an indoor scene that we captured, this time with a variety of different hidden objects. And these objects have different appearances, so they reflect light differently. For example, this glossy dragon statue reflects light differently than the mirror disco ball or the white discus thrower statue. And we can actually see the differences in the reflected light by visualizing it as this 3D volume, where we've just taken the video frames and stacked them together. And time here is represented as the depth dimension of this cube.
These bright dots that you see are reflections of light from each of the mirrored facets of the disco ball, scattering against the wall over time. The bright streaks of light that you see arriving soonest in time are from the glossy dragon statue that's closest to the wall, and the other streaks of light come from reflections of light from the bookcase and from the statue.
