JPL's Remote Interactive Visualization and Analysis System (RIVA) is described in detail. RIVA's kernel is a highly scalable perspective renderer tailored especially for the demands of large datasets beyond the sensible reach of workstations. The algorithmic details of this renderer are described, particularly the aspects key to achieving the algorithm's overall scalability. The paper summarizes the performance achieved for machine sizes up to more than 500 nodes and for initial input image/terrain bases of up to a gigabyte.The RIVA system integrates workstation graphics, massively parallel computing technology, and gigabit communication networks to provide a flexible interactive environment for scientific data perusal, analysis and visualization. Early experience with using RIVA to interactively explore multivariate datasets is reported and some example results given.
COAST, the Controller's Assistant, is a semi-automated player of the CBS wargame training simulation.It uses rule-based techniques to maneuver a collection of platoons through a complex infiltration mission in response to a single high-level order from a CBS controller.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
