Open Source Unix Shell Data Management Systems

VirtualGL redirects 3D commands from a Unix/Linux OpenGL application onto a server-side GPU and converts the rendered 3D images into a video stream with which remote clients can interact to view and control the 3D application in real time.

SaVi - simulate Starlink, Iridium, Globalstar, O3b, GPS, Galileo and other satellite constellations, modify them, or design your own. Requires Tcl/Tk and Unix libraries; 3D viewing option requires Geomview running on X Window.

High Dynamic Range Visual Difference Predictor (HDR VDP) is a perceptual metric that can predict whether differences between two images are visible to the human observer or not.

Conic Planet is a CGI application which renders a photo-realistic real-time image of the Earth and other planets. It has support for Azimuthal, Mercator, Mollweide, Orthographic, and Rectangular projections. It also shows the current cloud covering.

FrAid(FRactal AID) is an interface to Java, allowing it to proc. math. data(functions/equations). A compl. standalone system utilizing the FrAid prog. lang. is available(no need to be Java programmer to use it!). Use instead of Matlab. High res. graphics

Very basic RRDtool tutorial. It is an example in that way. It can save you a couple of days of discovering on your own. In any case you have to read the manual _before_ that ;)

Theophanu defines the data-structure and the processing logics to control daylight simulations with Radiance on hierarchical models. It was developed together with a detailed simulation model of late antique Hagia Sophia in Istanbul as part of a research project at TU Darmstadt, supported by the DFG German Research Foundation, grant #5194526: "Die Hagia Sophia Justinians in Konstantinopel als Schauplatz weltlicher und geistlicher Inszenierung in der Spätantike" (http://gepris.dfg.de/gepris/projekt/5194526). Theophanu is implemented as a set of Makefiles, that are understood by gnumake (and possibly other, compatible software). It controls the open source, daylight simulation suite Radiance.

A tool for making enhanced typesetting in xfig easy. It is using latex for setting the text.
