SaVi is satellite visualization software that lets you create, run, examine, and modify satellite orbits in two and three dimensions. Simulations of Iridium, Globalstar, Galileo, GPS, and other satellite constellations are included. SaVi requires Tcl and Tk on a system with Unix libraries. SaVi works well with the 3D renderer Geomview. Geomview is optional, though recommended for its 3D rendering capabilities.
Chaos Visualization is a program for quickly calculating the amount of predictability in a very simple system: a spring with one side connected to the origin and the other to a weight under gravity. This amount is chaos is visualized in TIFF images, which can be put in a sequence to show the evolution of chaotic behaviour in this system.
Range Software is software for finite element analysis (FEA) in engineering simulations. Its main features are support for Computational Fluid Dynamics (CFD), heat transfer and radiation, linear stress-strain, electro-statics, acoustics, ground water flow, shape optimization, 3D mesh generation, an intuitive GUI, and import and export functionality. The Range Software package contains several tools which helps the user to setup, solve, and analyze the engineering problem.
TheCurves is an application that plots a parameterized family of curves based on algebraic formulas specified by the user. It is meant as an educational tool for mathematics, physics, and engineering. When the program is run as an applet in a Web page, the plot parameters and formulas are configurable by HTML and dynamically scriptable, so that the applet can be initialized to present a specific plot when the page is opened or to change plots when the user clicks on a control in the Web page.
OpendTect is a seismic interpretation software system. It enables you to process, visualize, and interpret multi-volume seismic data using attributes and modern visiualization techniques such as stereo viewing and volume rendering. Visualization elements can be moved freely through data space to interactively analyze data from stored volumes, or data calculated on-the-fly. For more advanced work, commercial plugins are available.
Quaternions are numbers with 4 parts: one for time and three for space. Command Line Quaternions is a set of command line functions that generate thousands of points of quaternions, which are fed into animation software. This forms the foundations of analytic animations, a logical extension of analytic geometry.
