Human binocular vision and acuity, and the accompanying 3D retinal processing of the human eye and brain are specifically designed to promote situational awareness and understanding in the natural 3D world. The ability to resolve depth within a scene whether natural or artificial improves our spatial understanding of the scene and as a result reduces the cognitive load accompanying the analysis and collaboration on complex tasks.
A light-field display projects 3D imagery that is visible to the unaided eye (without glasses or head tracking) and allows for perspective correct visualization within the display's projection volume. Binocular disparity, occlusion, specular highlights and gradient shading, and other expected depth cues are correct from the viewer's perspective as in the natural real-world light-field.
Light-field displays are no longer a science fiction concept and a few companies are producing impressive light-field display prototypes. This presentation will review:
· The application agnostic light-field display architecture being developed at FoVI3D.
· General light-field display properties and characteristics such as field of view, directional resolution, and their effect on the 3D aerial image.
· The computation challenge for generating high-fidelity light-fields.
· A display agnostic ecosystem.
Demo after the talk: The FoVI3D Light-field Display Developer Kit (LfD DK2) is a prototype, wide field-of-view, full parallax, monochrome light-field display capable of projecting ~100,000,000 million unique rays to fill a 9cm x 9cm x 9cm projection volume. The particulars of the light-field compute, photonics subsystem and hogel optics will be discussed during the presentation.
Thomas graduated from Texas A&M University in 1989 with a bachelor's degree in Computer Science. He has spent 25+ years developing, architecting, and managing computer software and hardware projects including processor logic synthesis and simulation, 2D image processing pipelines, 2D/3D and light-field rendering solutions, 3D physics engines and 2D/3D games.
Thomas has been a developer/manager with multiple visualization start-up companies in and around Austin's Silicon Hills. At Applied Science Fiction (ASF) he co-developed image processing libraries and a processing pipeline to render images from exposed yet undeveloped 35mm film. As the software lead at Zebra Imaging, Thomas was a key contributor in the development of static light-field topographic maps for use by the Department of Defense in Iraq and Afghanistan. He was the computation architect for the DARPA Urban Photonic Sandtable Display (UPSD) program which produced several wide-area light-field display prototypes for human factors testing and research.
More recently, Thomas launched a new light-field display development program at FoVI3D where he serves as President and CTO. FoVI3D is developing a next-generation light-field display architecture and display prototype to further socialize the cognitive benefit of spatially accurate 3D aerial image.
