GeoPrO

What is it about

Keywords: Computational Geometry, Distributed Visualization, Oriented Projective Plane

GeoPrO is a programming environment for distributed visualization of geometric data over the Internet developed at the Institute of Computing at UNICAMP (State University of Campinas):

Key Benefits

	distributed programming environment;
	visualization systems (flat model and spherical model);
	and much more: see the detailed description.
