Graphics Systems

The first pure molecular graphics system followed after a few years. It was built in 1970 by Langridgc at Princeton University 195], The system was based on the Picture System 2 of Evans and Sutherland and could also display bonds and colored atoms.

This decade also saw the first major developments in molecular graphics. The first multiple-access computer was built at MIT (the so-called project MAC), which was a prototype for the development of modern computing. This device included a high-performance oscilloscope on which programs could draw vectors very rapidly and a closely coupled trackball with which the user could interact with the representation on the screen. Using this equipment, Levinthal and his team developed the first molecular graphics system, and his article in Scientific American [25] remains a classic in the field and laid the foundations for many of the features that characterize modern day molecular graphics systems.

Version for Windows . To execute the programs in this version, a compatible PC installed with the Windows 3.1., or later, graphic system and a hard disk with at least one Megabyte free is required. 

This manual assumes that the user is familiar with a Macintosh or Windows-type graphic operating system, with a mouse, windows, pop-up menus, etc. If this is not so, the user should first familiarise him/herself with the graphic system installed in his/her computer.
