PlotStuff: A class for plotting stuff from overture based on: GL{underscore}GraphicsInterface: A graphics interface based on OpenGL based on: GenericGraphicsInterface: A generic graphics interface: User guide, Version 1.00

{bold PlotStuff} can be used to interactively plot objects from Overture such as mappings, grids and grid functions. PlotStuff can be used to plot contours, surfaces, streamlines and grids. It can also be used to plot one-dimensional line plots. {bold GL{emdash}GraphicsInterface} is a class (from which PlotStuff is derived) that implements some standard plotting functions using OpenGL. {bold GL{emdash}Graphicslnterface} is itself derived from the class GenericGraphicsInterface which defines some standard plotting functions that are independent of any particular graphics package
