Abstract
J.J. Koenderink and A.J. van Doorn (1979) introduced aspect graphs
as a way of representing 3-D shape for object recognition. The set of
viewpoints on the Gaussian sphere is partitioned into regions such that
in each region the qualitative structure of the line drawing remains the
same. The viewing data of an object are the partition of the Gaussian
sphere together with representative line drawings for each region of the
partition. The authors present an algorithm for computing the viewing
data of polyhedral objects. In the course of presenting the algorithm,
they provide a full catalog of the visual events that occur for this
type of object
