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 and representative line drawings for each region of the
partition. An algorithm is presented for computing the viewing data of
polyhedral objects. A full catalog of the visual events that occur for
polyhedral objects is provided
