Abstract
We explore here the capabilities and performance issues
encountered when using a novel static volume display, CSpace,
for realizing moving images required to deliver real time three-dimensional
(3D) visualization and manipulation for Air Traffic
Controllers (ATC). The display uses a 19 mm x 18 mm x 100 mm
2% Erbium-doped sodium–ytterbium–fluoride (NYF) crystal
as the image space, and a pair of digital micromirror devices
(DMD) to address and render successive slices of the image within
the crystal. Display-specific software and digital light processing
(DLP) boards provide image data to and control the DMD devices
respectively. The ability to render and display moving images
quickly enough for applications such as air-traffic control is
strongly dependent on several factors, including the speed of the
software and hardware components. 3D images of aircraft in the
sky and terrain were captured to explore how well the display
performed as the time between successive images in a short motion
sequence was systematically reduced, and to examine the key
factors that control the performance of the display in presenting
these images.
