SImg is a software for astronomical image processing. It contains a tool for visualization of highly dynamic images. The package consists of a library and applications which use it. Some of the features are deconvolution (various methods), Video4Linux support, PSF computation, approximation by linear combination of images and polynoms, various color transforms, automatic shifting of image sets (for addition and color composition), and more.
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.
Qastrocam is a capture program that can work with any video4linux device. Its main purpose is to do astrophotography. It can control a telescope to do guiding with the images received from the video device. It can also control the extended features of a webcam modified to do long exposure (several seconds) captures.
AstroMosaic is a small commandline program to help the creation of a mosaic (a big image that is a collection of smaller images). It can automatically find the best aligment of the images. Its main goal was to compose astronomical images from a Webcam. It can take any image format supported by Qt as input.
PP3 creates celestial charts. It generates resolution-independent maps of very high graphical quality. They can be used, for example, as illustrations in books or on Web pages. It is possible to change many parameters, and arbitrary text can be placed on the maps. The output formats are EPS or PDF.
Mars MOLA Viewer displays a fly-over rendering of the Martian surface, as measured by the Mars Global Surveyor, in real-time 3D animation. It downloads the Mars Orbiting Laser Altimeter topographic data files and uses them to drive the rendering. The user controls the position and the angle of the camera, and can move seamlessly over the entire Martian surface from -88 to 88 degrees latitude. It is a Java Web Start program with 1-click installation from your browser (depending on platform/browser).
skyviewer is an OpenGL-based program to display HEALPix-based skymaps, saved in FITS format files. The loaded skymaps can be viewed either on a 3D sphere or as a Mollweide projection. In either case, realtime panning and zooming are supported, along with rotations for the 3D sphere view, assuming you have a strong enough graphics card.
Simulum deals with different simulations of star movements and their visualizations. At first it looks at the projection and accumulation of star brightness. In actually doing this it distributes stars among a three dimensional figure. To get a nice effect it combines the photographic image production with a moving view point. So the outcome is the visual impression of flying through a star field. Secondly it studies different algorithms of particle movements and clustering. The primary approach uses a combination of Newton's gravitational law, energy, and impulse conservation. At all these stages an highly dynamic view of the processes is able to be produced.
