BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
CMake is a cross-platform, open-source build system. It is used to control the software compilation process using simple platform and compiler independent configuration files. It generates native makefiles and workspaces that can be used in the compiler environment of your choice. CMake is quite sophisticated: it is possible to support complex environments requiring system configuration, pre-processor generation, and code generation.
TacitPixel (formerly libTAP ) is a prototyping system for virtual reality and augmented reality applications. It runs on a variety of platforms. RAP (rapid application prototyping) is done through the Lua interface, which mirrors the C++ namespace as closely as possible. libTAP has a small but distinctive feature set, focused on prototyping of realtime 3D simulations.
ZUPS allows for monitoring the state of one or more UPS devices using SNMP and executing user-specified commands in case of power outage, such as email notifications and controlled remote host shutdowns. If the UPS devices are running on battery, the shutdown commands are executed for an arbitrary number of remote hosts, optionally with some delay specified for each host. ZUPS can be configured to ignore these delays and run the specified commands immediately if the UPS devices are running out of battery power. Custom plugins can easily be added in order to perform other checks.
LibJAD is collection of miscellaneous routines for a variety of purposes. This library includes functions of reading ini style files, multi-threaded programming, finding the number of processors available on the system, computing combinations and permutations, base64 and URL encoding, and working with ASN1 and PGM files.
