Glasses-Free 3D Telepresence

Volumetric calls on a 45-inch autostereoscopic display, no glasses required.

We specified and selected the display hardware, a 45-inch autostereoscopic panel that shows 3D without glasses, and built and calibrated a custom wide-aspect capture rig for the best realtime volumetric capture we could get.

On the software side we implemented:

  • Volumetric streaming over RTC, with higher-quality stitching from several sensors.
  • 9-view reconstruction of the volume for high-quality glasses-free 3D.
  • Face tracking on the receiving end to drive parallax and adjust perspective, so background replacement looks right as the viewer moves.
A six-step flow: a custom wide-aspect capture rig, higher-quality stitching of several sensors, volumetric streaming over RTC, 9-view reconstruction, face tracking on the receiving end, and a 45-inch autostereoscopic display with background replacement.
Each call passes through stitching, an RTC stream and 9-view reconstruction before reaching the glasses-free display.

Recording an autostereoscopic display on video is notoriously hard, so this one is best seen in person.
