Both James Gibson's ecological approach to vision and recent research
in computer vision have challenged linear perspective as the foundatio
n for understanding either vision or pictures. There is a gro wing app
reciation of the diversity of informative structures available to perc
eivers, and of the fact that many of these structures are not tied to
any single viewpoint. The convergences between these approaches are ex
plored with reference to the existing research on picture perception a
nd production.
