We present DIVERSE, a highly modular collection of complimentary software packages designed to facilitate the creation of device independent virtual environments. DIVERSE is free/open source software, containing both end-user programs and C++ APIs (Application Programming Interfaces). DgiPf is the DIVERSE graphics interface to OpenGL Performer™. A program(More)
Spatial-temporal correlations in the startup-up flow of colloidal suspensions composed of attractive spherical particles under static and shear conditions are studied by computer simulation. The evolution of particle organization with time is followed as equilibrium is approached. The time dependence of the radial distribution and organization of nearest(More)
This paper describes a set of tools for performing measurements of objects in a virtual reality based immersive visualization environment. These tools enable the use of the immersive environment as an instrument for extracting quantitative information from data representations that hitherto had be used solely for qualitative examination. We provide, within(More)
This is the second in a series of articles describing a wide variety of projects at NIST that synergistically combine physical science and information science. It describes, through examples, how the Scientific Applications and Visualization Group (SAVG) at NIST has utilized high performance parallel computing, visualization, and machine learning to(More)
The rate of scientific discovery can be accelerated through computation and visualization. This acceleration results from the synergy of expertise, computing tools, and hardware for enabling high-performance computation, information science, and visualization that is provided by a team of computation and visualization scientists collaborating in a(More)
In this paper we describe a flexible environment that combines scientific data mining with parallel computing in an immersive visualization environment. The goal is to minimize the time between the generation of a scientific hypothesis and the test of that idea, or science at the speed of thought.
We describe a method for calibrating an electromagnetic motion tracking device. Algorithms for correcting both location and orientation data are presented. In particular we use a method for interpolating rotation corrections that has not previously been used in this context. This method, unlike previous methods, is rooted in the geometry of the space of(More)
A Computer Aided Ship Design (CASD) and a Computer Aided Manufacturing (CAM) program are described. The objective of the program is to provide the capability to design and manufacture towing tank models using interactive CASD and CAM techniques. A three dimensional interactive graphics device supported by a mini-computer is used to drive the design portion(More)
