Assignment 1 Questions

1. Control is passed back to the programmer via callback functions. These callback functions are called whenever an event happens that a program can react to. This is set up during initialization by setting function pointers to the user defined functions in such methods as glutDisplayFunc( display ).

2. The parameters specify what color scheme we wish to use and whether we want to use double buffering.

3. glOrtho() sets up the viewable space of the "infinite sheet" that our window can see. glViewPort() allows us to specify what part of the window that we wish to draw onto.
