Coin is an implementation of Open Inventor. Open Inventor is the de facto standard API for retained-mode 3D graphics programming. Open Inventor has a highly extensible design, and has been designed to allow for rapid development of highly interactive 3D graphics applications in the fields of CAD, engineering, scientific computing, simulation, VRML, and visualization.
Common C++ RTP is an experimental threadsafe RTP stack for use with Common C++. It uses a service thread to both schedule outgoing packets and organize arriving packets. Queued lists of packets are maintained both for sending and receiving, and packet payloads can be mixed such as for passing RTP telephony events. Recent builds of GNU ccRTP are also available for building handheld softphone clients using Open Embedded.
csv2png and csv2jpeg use the GD library to plot time series data from a CSV file to either a PNG or a JPEG graphic. The program is deliberately simple, and is targeted at CGI applications. Originally written for RISC OS as csv2gif (see Acorn User, issue 215) the latest distribution builds on Linux as well.
