Virtual Worlds 2000 is the second in a series of international
scientific conferences on virtual worlds held at the International
Institute of Multimedia in Paris La Défense (Pôle Universitaire Léonard
de Vinci). The term "virtual worlds" generally refers to virtual reality
applications or experi ences. We extend the use of these terms to
describe experiments that deal with the idea of synthesizing digital
worlds on computers. Thus, virtual worlds could be de fined as the study
of computer programs that implement digital worlds. Constructing such
complex artificial worlds seems to be extremely difficult to do in any
sort of complete and realistic manner. Such a new discipline must
benefit from a large amount of work in various fields: virtual reality
and advanced computer graphics, artificial life and evolutionary
computation, simulation of physical systems, and more. Whereas virtual
reality has largely concerned itself with the design of 3D immersive
graphical spaces, and artificial life with the simulation of living
organisms, the field of virtual worlds, is concerned with the synthesis
of digital universes considered as wholes, with their own "physical" and
"biological" laws.
