Researchers at Purdue University say they have developed Holostream, a platform enabling high-quality three-dimensional (3D) video communications on mobile devices.

Purdue professor Song Zhang says Holostream reduces the data size of 3D video without substantially sacrificing data quality, permitting the transmission of video files within the bandwidths provided by existing wireless networks.

Zhang notes the breakthrough could improve teleconferencing and telepresence, which uses virtual reality and other interactive technologies to enable users to feel or appear as if they were present in a remote location.

"This technology also could enable emerging applications that may require high-resolution, high-accuracy 3D video data delivery, such as remote robotic surgery and telemedicine," he says.

Holostream converts 3D video into a two-dimensional (2D) format, so users can leverage 2D communication platforms for low-bandwidth 3D video communications. When applied to the Holostream platform, 3D objects are represented by a mesh of intersecting lines forming triangles, atop of which a "texture" of features is placed.
