Light-field displays have moved beyond the realm of science fiction, with prototypes now existing in the real world. Light-field computation, however, is the barrier to deployment. The sheer number of pixels required to produce high-fidelity light-field content at a reasonable cost represents a daunting though not unsolvable problem.
August 31, 2017 Austin, TX. FoVI3D installed the first ever light-field display metrology system at Wright-Patterson Air Force Base as part of the Small Business Innovative Research Program, Holographic Light-field 3D Display Metrology (HL3DM). Dr. Darrel Hopper and his team in the 711 Human Performance Wing initiated this effort to support the test, validation, and performance evaluation of a new class of emerging display technologies. FoLD 3D visualization systems that enable multi-user full-parallax viewing of complex 3D data without eyewear, are being developed with the aim of increasing the productivity of operators and analysts in Operations Centers. Currently, the lack of validated metrics (physical and perceptual) is a major hindrance for the successful technology transition and commercialization of such FoLD systems as holographic, volumetric, multi-planar and light-field displays.
The FoVI3D delivered Field of Light Display Metrology System (FoLDMS) consists of a mechanical sweeping gantry for a pair of stereo cameras capable of measuring both horizontal and vertical field of light displays. The delivery includes three FoVI3D custom applications to characterize, capture, record, and qualify physical light-field performance. A companion Human Factors Metrology Application (HFMA) is under development to understand and quantify the psychophysical measurements associated with FoLD systems.
“This effort has afforded many unique challenges such as the capture of ethereal, 3D aerial images from multiple perspectives from which to quantify FoLD metrology. But it has been the decomposition of those images into actual 3D aerial metrics that posed the greatest opportunity for exploration,” Dr. Abhishek Bichal, FoVI3D Metrology Engineer.
Thomas Burnett, CTO, states that, “These methodologies and applications will allow researchers and engineers to better understand the physical and human factor properties of their displays, removing much of the subjective nature of light-field display design and development.” As the computation architect of the first ever interactive light-field display table, he understands both the challenges and needs for a practical, automated, repeatable process to define the visual performance of these emerging displays.
Led by the U.S. Air Force in the early 1990s, the digital pixelated flat panel displays (FPD) class of 2D displays went through this metrics and metrology development phase. By the early to mid-2000s, the main 2D display technology on the planet (by units shipped and dollar sales) transitioned from the analog cathode ray tube (CRT) class to the FPD class. This epochal shift from CRTs to FPDs could not have occurred without the FPD test and evaluation methodologies and standards. By developing a practical, affordable, and repeatable evaluation procedure, a similar acceptance in 3D FoLD systems will be created.
22 August 2017 - FoVI3D was selected and awarded a phase I contract from the U.S. Navy to develop a light-field processing unit for an onboard display system that reduces the size, weight, power, and cost of real-time synthetic light-field generation. This effort is one building block in support of the overarching goal of providing a collaborative, multi-view light-field display system for use in command and control environments to increase our spatial understanding of a complex scene while reducing the cognitive load and providing greater confidence in rapid response decisions. Light-field radiance image rendering is the process of rendering all the perspective views present in the light-field from 3D data regardless of viewer position. To implement multi-view rendering with a GPU requires that the host application dispatch a render pass for each viewpoint (micro-lens) required for the projection system; a light-field projection system may contain thousands of micro-lenses. FoVI3D’s architectural approach is to refactor the GPU to render hogels in parallel and create a more efficient light-field/multi-view rendering engine.
The enclosure for the FoVI3D DK2 arrived today! Assembly has begun and we will deliver updates as they come!
Los Angeles, CA - May, 22nd, 2017 – Thomas Burnett, the CTO and Founder of FoVI 3D, will be speaking on two separate topics at the Society for Information Display’s Display Week 2017. As the chief software architect of the world’s first light-field display table and a world recognized expert in light-field displays, Burnett will be delving into Volumetric Virtual Reality (Holography and the Light Field) and Light-Field Display Architecture and the Challenge of Synthetic Light-Field Radiance Image Rendering. Burnett will be speaking both at Display Week’s AR/VR conference on Wednesday May 24th and the SID Symposium on Thursday May 25th.
SID’s annual Display Week runs from May 21st to May 26th at the LA Convention Center offering a wide selection of display technology presentations by global experts that simply cannot be found anywhere else.
Austin, TX - April, 10th, 2017 – FoVI3D was awarded a Phase II Small Business Innovation Research (SBIR) grant from the Naval Sea Systems Command to pursue the development of the next generation Full Multiplex Holographic Display (FMHD). This 2-year effort will advance holographic light-field display (LfD) systems addressing the needs of the Navy’s Combat Information Centers (CIC).
“The US Navy continues to be a great partner for FoVI3D” stated Chuck Scullion, chief executive officer of FoVI3D. “Considering our existing programs with the US Air Force and the US Army, this award further demonstrates the armed services’ desire for collaborative, glasses-free 3D displays. Considering our significant lead in the development of holographic LfD systems, FoVI3D is best positioned to realize this vision.”
The objective of the Full Multiplex Holographic Display (FMHD) Phase II is to further define the requirements of a collaborative, holographic LfD system and develop a prototype to meet US Navy needs. Increasing complexity and speed of future naval engagements will require an efficient and intuitive Common Operating Picture (COP) display system with perspective correct visualizations of the battlespace. This will include expected depth cues such as occlusion, gradient shading, and specular highlights for all viewers within the light-field projection volume without the need for eye tracking or VR headsets. This will bring key stakeholders and decision makers together over a LfD system with enhanced collaboration and information retention.
The first ever working prototype of a holographic LfD for real-time battlespace visualization was created through the Defense Advanced Research Projects Agency (DARPA) funded effort Urban Photonic Sandtable Display (UPSD) program. This 5-year effort resulted in the creation of four LfD systems, three of which were transitioned to agencies within the Department of Defense (DoD) for human factors research and experimentation. FoVI3D is now advancing this technology to create the next generation holographic LfD to meet the DoD vision for collaborative, glasses-free 3D display systems and the support of US Navy’s SBIR award accelerates this development.
Chantilly, VA - January, 10th, 2017 - As part of its work with the Air Force Research Laboratory, FoVI 3D is hosting a symposium on government streaming and content needs for Field of Light Displays (FoLDs). The objective of this symposium is to collectively understand the overall vision from the various US government agencies for the capture-to-display requirements of 3D data on FoLD systems.
Collection, storage, transmission, and viewing of 3D data captured by a variety of DoD sensor systems has increased dramatically over the past 15 years and even more rapid growth is anticipated. Advancements in visualization of this data has not, however, kept pace. To help close the gap between collection and the ability to exploit the data, the Air Force has identified a requirement for true 3D visualization systems to increase productivity of operators dealing with the 3D data deluge. The Air Force further requires the data be viewed without special eye wear on a new class of display, FoLD visualization systems.
As a developer of light-field display tables, FoVI 3D is keenly aware of the unique challenges in streaming 3D content for 360° viewing of a full parallax perspective correct image. With the belief that the future command centers will be a heterogeneous environment exploiting a variety of display types to provide the best visualization capability to accomplish the task at hand, FoVI 3D with support from Brigham Young University is strategically poised to lead this research to define a streaming 3D standard that is scene/data and display agnostic to create a common interface to all 3D displays.
Air Force Research Laboratory leads the research to develop a model for the multimedia data stream required for next-generation field-of-light display (FoLD) systems to project full-parallax video-rate 3D images without eyewear. Leading the investigation, FoVI 3D, with support from Brigham Young University on the Phase I Small Business Technology Transfer, will lead the research and define a streaming 3D standard that is scene/data and display agnostic in order to create a common interface to 3D displays. This nine month effort was officially kicked off on August 3, 2016.
Air Force Research Laboratory awards the Holographic Light-field 3D Metrology Small Business Innovative Research Phase II to FoVI 3D. This 2-yer effort defines and creates the metrology required to evaluate the novel light-field displays emerging to market.
Zebra Imaging was awarded the Phase II from Air Force Research Laboratory to pursue the next generation Holographic Video Display (HVD). This 2-year effort will be performed by the dynamic light-field display research and development business unit, FoVI 3D. Work on Gen2 is already underway and the support of AFRL's Small Business Research Laboratory Phase II award moves this development forward.
