Earth orbits and coverage display in 3D on your laptop.
SaVi - simulate Iridium, Globalstar, O3b, Sirius Radio, GPS, Galileo and other satellite constellations, modify them, or design your own. Uses Tcl/Tk and Unix libraries; 3D viewing option requires Geomview running on X Window.
Open Source Solid Modeling CAD
BRL-CAD is a powerful cross-platform constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing for rendering & geometric analyses, network distributed framebuffer support, image & signal-processing tools.
UPDATE: Chromium is no longer updated or maintained. The project is frozen. Chromium is a flexible framework for scalable real-time rendering on clusters of workstations, derived from the Stanford WireGL project code base.
A multi-platform collection of C++ software libraries for Computer Vision and Image Understanding.
Framework to generate TclkitLite executables, compile Tcl packages and build kit files for different operating systems
VAPOR is the Visualization and Analysis Platform for Ocean, atmosphere, and solar Research
Multicore SWARM (Software and Algorithms for Running on Multicore Processors) is an open source library for developing efficient and portable implementations that make use of multi-core processors. David A. Bader (Georgia Tech) began SWARM in 1994.
zimg generates png / jpeg images from arbitrary formatted 2-D ascii or binary data. zimg is a command line tool and suitable for rendering large amounts of 2-D data. zimg is highly configurable via command line switches and dynamically loadable objects.
A replacement to traditional syslog daemons. Including cryptographic log protection, mysql, postgresql. Supported on Linux, BSD, Irix, Solaris and AIX.
Logsurfer is a program for monitoring system logs in real-time, and reporting on the occurrence of events. It is capable of grouping information together to enhance loganalysis and create automatic reports.
The Optimized Sparse Kernel Interface (OSKI) Library provides automatically tuned sparse matrix kernels, for use by solver libraries and applications. OSKI is part of the BeBOP project on performance tuning and analysis at U.C. Berkeley. (Go Bears!)
RealPaver is a modeling language for solving mixed-integer nonlinear constraint systems.
Nebula: A small and lean IRC client written for motif/lesstif. Small system requirements, speed, portability, security and a clean GUI are its strong points.
nwcc is a C compiler for Unix systems targeting *BSD, OSX, Linux and Solaris on x86 (nasm/gas), FreeBSD, OSX and Linux on AMD64 (yasm/gas), Solaris on SPARC, AIX and Linux on PPC/PPC64 and IRIX on MIPS64. Cross-compilation is supported.
A fast and lean render engine with multiple renderbackends
TacitPixel is a scalable C++ framework for building application prototypes for interactive collaborative VR/AR applications. It provides a number of features that make prototyping fast and portable. TacitPixel is the successor of the TAP and Twisted Pair engines.
LUNUS software for generating 3D maps of diffuse scattering from macromolecular X-ray crystallography diffraction images. Also see http://lunus.sourceforge.net
An extension of the HPVM Project. Tala aims at being a powerful cross-platform cluster programming language that allows programs to be written once, and run on may OSes. Support will be provided for auto vectorization, optimization and cross compiling.
Ayam is a free 3D modelling environment for the RenderMan interface.
MVS - Math Visualization System (See description on homepage)
The IRIX Software Project is an initiative to port open-source software to the IRIX operating system running on Silicon Graphics workstations. It is also a goal to foster development of new software which makes full use of SGI's APIs.
Cross platform libraries and tools that may make your life easier.
GGI stands for "General Graphics Interface", and it is a project that aims to develop a reliable, stable and fast graphics system that works everywhere. We want to allow any program using GGI to run on any platform requiring at most a recompile.
