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.
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.
OpenEV is a library and reference application for viewing and analysing raster and vector geospatial data. OpenEV capabilities include the following: handling of raster and vector data, support for 2D and 3D display, graceful handling of very large (gigabyte) raster datasets, support for multi-channel raster datasets, understanding and interpreting of georeferencing information, pan/zoom/rotate at interactive frame rates (using OpenGL), and a powerful image analysis tool (using Numerical Python).
OpenVRML is a VRML and X3D browser plug-in and C++ toolkit for incorporating VRML/X3D support into applications. It provides VRML97 and Classic VRML X3D parsers, a runtime, and an OpenGL renderer as C++ libraries. The renderer is fully separate from the runtime library so that users can also provide their own renderer. The OpenVRML browser is provided as a D-Bus service, and is embeddable in host applications using XEmbed. The distribution provides both a stand-alone host and a host that runs as a Mozilla plug-in.
VMD (Visual Molecular Dynamics) is designed for the visualization and analysis of biological systems such as proteins, nucleic acids, lipid bilayer assemblies, etc. It may be used to view more general molecules, as VMD can read standard Protein Data Bank (PDB) files and display the contained structure. VMD provides a wide variety of methods for rendering and coloring a molecule: simple points and lines, CPK spheres and cylinders, licorice bonds, backbone tubes and ribbons, cartoon drawings, and others. VMD can be used to animate and analyze the trajectory of a molecular dynamics (MD) simulation. In particular, VMD can act as a graphical front end for an external MD program by displaying and animating a molecule undergoing simulation on a remote computer. VMD uses OpenGL and OpenGL Programmable Shading Language for high performance rendering of large structures.
WilmaScope is a Java3D application that creates real-time 3D animations of dynamic graph (network) structures. It comes with a number of layout algorithm plugins, and supports the easy creation of plugins for new layout algorithms. 3D geometries for graph element glyphs and algorithms for graph generation and modification are loaded dynamically as plugins, providing an extremely flexible platform for all manner of graph visualisation applications. The system has been applied with considerable success to a number of graph visualisation problems.
Teddy is an OpenGL-based 3D graphics library written in C++. Its main features are simple scene graph and windowing system-enabling multiple cameras, camera windows, and scenes. It focuses on easy and flexible manipulation of models and model materials in the scene graph. It contains a number of primitive objects like sphere, box, and cone, and it can load LightWave object and scene files.
ImLib3D is a C++ library and visualization system for 3D (volumetric) image processing. It contains most basic image processing algorithms, as well as some more sophisticated ones. Its images are STL-compliant templated containers. It inculdes a viewer that features multiplanar views, interactive image processing, animations, vector field views, and 3D (OpenGL) multiplanar. Its main application is medical image processing.
aiSee reads a textual, easy-to-read, and easy-to-learn graph specification and automatically calculates a customizable graph layout. This layout is then displayed, and can be printed or interactively explored. aiSee features 15 basic graph layout algorithms (including force-directed layout), recursive subgraph nesting, fish-eye views, and an animation interface. It has been optimized to handle huge graphs automatically generated by applications (e.g. compilers).
