We are investigating computer
graphics techniques to simplify and
accelerate image generation
for displays (holographic stereograms
in particular) that incorporate
numerous perspective
views of
computer-rendered data
. Currently,
our "render-on-demand"
method of holographic
printing requires high-speed image
generation which is compatible
with both one-step and master-
transfer recording geometries.
Our techniques for image generation
rely upon the widely
available OpenGL graphics library and take
advantage of acceleration
by computer graphics hardware
subsystems.
By exploiting perspective
coherence, Multiple
Viewpoint Rendering
extends conventional
scanline rendering algorithms to provide large
sets of perspective images
at rates one to two orders of magnitude
faster than traditional
rendering methods. This algorithm can generate
high quality images using
texture and reflection maps, and can be
accelerated by using
existing graphics hardware. The image sets
rendered using this algorithm
can be used as input to image-based
rendering systems, and
as component frames for multiperspective
displays.
