Stereoscopic Ray-Tracing

Abstract:
In this paper, we describe a method to create an
approximate ray-traced stereoscopic pair by transforming a fully
ray-traced left-eye view into an inferred right-eye view.
Performance results from evaluating several random scenes are given
which indicate that the second view in a stereoscopic image can be
computed with as little as 5% of the effort required to fully
ray-trace the first view. We also discuss worst case performance
of our algorithm, and demonstrate that our technique will always be
at least as efficient as two passes of a standard ray-tracer.
