Abstract
The demand and applications for three-dimensional (3D) display systems
is rapidly increasing. Many innovative, truly 3D display technologies have
recently been developed, particularly those in the category of volumetric
displays. However, currently no large format displays can produce true 3D
images. They are either two-dimensional (2D) displays and represent the third
dimension using well known techniques of shading and shadowing, or they are
not full parallax displays and require the viewer to wear special head gear.
There are many applications for large, truly 3D displays including billboards,
kiosks, theaters, medicine, radar imaging, military and entertainment. To
meet these growing applications, we introduce a large swept-volume display
(LSVD) that is capable of displaying full-motion 3D video. The LSVD is comprised
of several rotating panels; each rotating panel contains several image panes,
and each image pane contains a field-programmable gate array (FPGA) that controls
light-emitting diodes (LEDs). The rotating panels fill the volume of a cylinder
that makes up a column of the display. The derivation of parameters for the
arrangement of columns and the overlapping regions between the columns is
also presented. In addition, an image partitioning algorithm that partitions
the full image into the LSVD columns is provided along with the original circuit
designs of a rendering algorithm for providing real-time, full-motion 3D video
for SVDs.
