The world of workstations changed dramatically with the release of the X Window System. Users could finally count on a consistent interface across almost all makes and models of computers. At the same time, graphics applications became easily portable. Until recently, X supported only 2D graphics. Now, however, by means of the PEX extensions to X, together with the PEXlib applications programming interface, native, 3D graphics have come to the X Window System. PEXlib allows the programmer to create graphics programs of any complexity, and also provides the basis for higher-level graphics systems and toolkits. The PEXlib Programming Manual is the definitive programmer's guide to PEXlib, covering PEX versions 5.0 and 5.1. Containing over 200 illustrations and 19 color plates, it combines a thorough and gentle tutorial approach with valuable reference features. Along the way, it presents the reader with numerous programming examples, as well as a library of helpful utility routines--all of which are available online. You do not any need prior graphics programming experience to use this manual. Written by Tom Gaskins--the widely recognized authority who also authored the O'Reilly and Associates PHIGS Programming Manual--this book is the only programming guide to PEXlib you will ever need.
