// Question 1: In a GLUT program, how is control passed // back to the programmer? How is this set up during // initialization?

Control is passed back to the programmer through the use of function pointers. Specifically glutDisplayFunc, glutTimerFunc, glutReshapeFunc, glutKeyboardFunc,

  • etc all have function pointers as arguments.

// Question 2: What does the parameter to glutInitDisplayMode() // specify?

The parameter to glutInitDisplayMode is a bitmask that corresponds to enabling/disabling display preferences. Thus far, we've used options that toggle between RGBA color mode or color indexing, and double or single buffering (for the swapbuffers vs flush).

// Question 3: What do the calls to glOrtho() // and glViewport() accomplish? GLOrtho appears to control what portion of the rendering is displayed in the viewport. It seems similar to a camera. glViewport sets the portion of the window that will correspond to the preceding camera output. This input is the bottom left corner of the viewport, followed by its dimensions.
