KiNG (Kinemage, Next Generation) is an interactive system for three-dimensional vector graphics. It supports a set of graphics primitives that make it suitable for many types of graphs, plots, and other illustrations; although its first use was to display macromolecular structures for biophysical research. KiNG builds on Mage, JavaMage, and the "kinemage" (kinetic image) concept to deliver a full-featured Java application with a user-friendly interface and integrated editing features. It also operates as a Java applet to promote easy access to kinemages from a web browser.

Dang reads coordinates from a Protein DataBank (PDB) molecular structure file and generates a table of several useful geometric measurements for each residue or base. In its most basic form, it writes out dihedral angles (phi, psi, chi) hence the name. The output is formated for easy parsing by awk, grep, sort and other UNIX utilities.

YASARA View is available for free and contains all the functions you need to explore a macromolecular structure interactively. As a bonus, you get YASARA's innovative 3D engine, which is up to 35 times faster than what you usually know from OpenGL (see benchmarks ), you can load multiple structures at the same time, create publication-quality ray-traced images including labels, and program your own macros and Python plugins. Included is YASARA Movie, a player for multimedia presentations and tutorials created with any of the higher stages.

VMD 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.
