Short Description:

What makes an object appear to emit light, or glow? We show that perceived 3D shape is critical to the appearance of glow, and that we can toggle the perceived glow on and off when motion or disparity depth cues invert a surface’s perceived 3D shape.

Online Version of the Demo:

Here are stereopairs for experiencing the phenomenon.

Cross-fusing Image 1 and Image 2 yields the dark-valley stimulus, which does not appear to glow. Cross-fusing Image 2 and Image 3 yields the bright-valley stimulus, which does appear to glow.

However, please note that free-fusing the stimuli can be difficult and you may not experience the full effect; we plan to bring portable stereoscopes for Demo Night. We also provide the motion version of the demo below, which may be more effective for some viewers.
