What is it about
Keywords: Computer Graphics, Xlib, Xview, OO, Visualization
EGOLib is a library of functions built on the X-Window system for the manipulation of graphics objects, which provides facilities for the update of such objects while modifications of attributes of the objects are made. This library constitutes a level above the Xlib library, allowing the user a higher level access to modifications of various attributes on a homogeneous and uniform way, resulting in more elegant code than is possible using purely Xlib functions. EGOLib was developed at the Institute of Computing at UNICAMP (State University of Campinas).
The concept of class hierarchy, present in object oriented languages, is used for creating the classes of graphics objects, from some simple ones up to composed objects such as binary trees.
Applications of EGOlib are abundant, and in particular, this library has been used for the implementation of algorithm animations.
