GraphCalc includes many of the standard features of graphing calculators, but also includes some higher-end features:
High resolution
Graphing calculator screens have a resolution typically less than 120×90 pixels, whereas computer monitors typically display 1280x1024 pixels or more.
Speed
Modern computers are considerably faster than handheld graphing calculators
Three-dimensional graphing
While high-end graphing calculators can graph in 3-D, GraphCalc benefits from modern computers' memory, speed, and graphics acceleration (OpenGL)
GraphCalc was developed by Brendan Fields and Mike Arrison, computer science students at Bucknell University, before graduating in 2000. Mike continued the development briefly from 2001–2003, but has since abandoned the project. Other similar projects being maintained are KAlgebra and Cantor.
