Abstract
Techniques are described for improving the speed and accuracy of
iterative visible-surface reconstruction algorithms. In particular, the
importance of obtaining accurate early information is emphasized, both
in the initial surface approximation and in the early localization of
surface discontinuities. The first of these goals is attained using a
simple technique known as constraint expansion, which yields a good
initial approximation while accounting for detected discontinuities. The
second goal is attained by using the locations of the image intensity
edges as a guide in locating potential discontinuities
