PAPFIP (Python And PGPLOT-based FITS Image Plotter) is a FITS image plotter based on the Python bindings to the pgplot graphics library. It is intended as a non-interactive (command line or script-driven) astronomical image plotter intended for the automated or repeated production of finalized publication-quality Postscipt files, rather than a method of inspecting or visualizing the data.
Extrema, originally developed in the fields of nuclear and particle physics, is a powerful visualization and data analysis tool that enables researchers to quickly distill their large, complex data sets into meaningful information. Its flexibility, sophistication, and power allow you to easily develop your own commands and create highly customized graphs.
ImageJ is an image processing program inspired by NIH Image for the Macintosh. It can display, edit, analyze, process, save, and print 8-bit, 16-bit, and 32-bit images. There are modules for biology, astronomy, nuclear medicine, physics, and more. If you can take a picture of something, whether with a microscope, a telescope, an oscilloscope, an xray machine, or a scanner, then this program will let you enhance, manipulate, and measure the results.
OpticalRayTracer analyzes systems of lenses. It uses optical principles and a virtual optical bench to predict the behavior of many kinds of ordinary and exotic lens types. It includes an easy-to-use interface that allows the user to rearrange the optical configuration by simply dragging lenses around using the mouse. It fully analyzes lens optical properties, including refraction and dispersion. The dispersion display uses color-coded light beams to simplify interpretation of the results.
CFITSIO is a library of C and Fortran subroutines for reading and writing data files in the FITS (Flexible Image Transport System) data format. It simplifies the task of writing software that deals with FITS files by providing an easy to use set of high-level routines that insulate the programmer from the internal complexities of the FITS file format.
EQUINOX-3D is a 3D modeler with a very fast, fully integrated ray-tracer. It features read/write support for COLLADA, read support for Radiance's .hdr image format, 3DS (3D-studio) file format read support, multi-texturing, custom-programmable texture mapping, bump-mapping with automatic texture-space tangents, the ability to zoom into a region with "fly-to", and more. It includes a full runtime-class framework and a core design that allows for the addition of anything from a physics engine to a fully integrated renderer from a plugin. It is faster and more memory efficient than many other modelers.
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.
McIDAS-Lite is a freely available demo for the full McIDAS software. It will connect to a variety of free online data sources for satellite data and display the images in a viewing window. Images can be looped and analyzed, and graphics overlays can be created to show maps and other geographical features. It is available for AIX, HP-UX, Irix, Linux, Mac OS X, Solaris Sparc, Solaris x86, and Windows XP with SFU.
