3D-SVD
3D-SVD (swept volume
display) is one of several 3D image projection technologies
currently being developed by 3DIcon Corporation. This technology
creates a volumetric image that floats in air, occupying 3D
space without the use of a 2D screen or viewing aids, in a full
color true-to-life format that can be viewed from any angle with
the naked eye.
3D-SVD is a volumetric display in which a true three dimensional
image is formed by illuminating a rapidly moving display
surface, such as a circular screen rotating at an optimal rpm
(revolutions per minute), sweeping a spherical volume. A
collection of voxels (volumetric pixels) is rendered at precise
locations within the volume over a period of time, resulting in
3D imagery due to persistence of vision.
Swept Volume Volumetric displays were first postulated nearly a
century ago and have been a staple of science fiction. Until
recently its development has only been accessible to research
institutions, the military and now leading technology companies
like 3DIcon. The 3DIcon technology incorporates cutting edge
electronics
Our research team at OU has completed Stage I of the 3D-SVD
development program, which took the technology from concept
stage to successfully rendering full color, 3-dimensional,
360-degree volumetric images. The embodiments of the original
patent claim filed by OU for the 3D-SVD technology include full
color, 360-degree, 3D video images using LEDs (light emitting
diodes) operating at an optimal rpm to create a solid-appearing
image with negligible flicker. The completed demonstration
system has delivered on the ability to create full color,
360-degree 3D images.
The 3D-SVD system development was a multi-disciplinary effort
that included expertise covering electronics, software
engineering, optics, photonics, electrical engineering as well
as mechanical engineering. The Stage I development process
overcame major technical hurdles and successfully demonstrated a
unique approach for 3D Image displays.
As the technology continues to develop in Stage II, the goal is
to create image quality that appears more solid with negligible
flicker. Over the next 12 months, 3DIcon and OU expect to
complete Stage II of SVD and bring the technology to a point
where specific industrial applications may be developed and
hence commercialized. Specific performance goals include
investigating alternate image pane technologies with 3 color LEDs; demonstration of increased rpm capability; and creation of
opacity/directionality.
SVD is well suited for outdoor formats for use in advertising
and entertainment, yet it’s been designed for flexibility and
functionality including scalability for larger displays,
automated 3D image preparation and importation software, and
variable clock image display control.
The Stage I system features:
Automated 3D importation and image control software
Support for Blender(OGL) Import
Image Compression/Decompression support
Variable clock image display control
1024 image slices per revolution
Over 4 million voxels rendered per revolution
512 Field Programmable Gate Arrays (FPGAs) programmed and
running in parallel
Graphics memory reading capabilities that are almost 150 times
that of current high end PC graphics cards
