Ptplot is a set of Java classes that can be used as an applet or an application for graphing datasets. It reads PlotML, binary, or ASCII data, is autoranging, and automatically or manually labels axes and tick marks. It can plot live, animated plots and provides zooming. It also includes Bourne shell scripts and DOS .bat files that can be used as a replacement for xgraph, the X11 graphing tool.
JOGL is a reference implementation of the Java bindings for the OpenGL API, which is designed to provide hardware-supported 3D graphics. It provides full access to the APIs in the OpenGL 1.4 specification as well as nearly all vendor extensions, and integrates with the AWT and Swing widget sets.
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.
Libgvectors is a C++ library for visualizing three dimensional mathematical vectors, providing three fundamental classes for achieving its purpose. It makes as few assumptions as possible about the graphics library used to draw vectors on a screen and is not bound to any particular graphics library.
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.
