This tutorial gives you the knowledge to tell if a pointer or object is in your frustum.  This is the first step in space partitioning, a technique which speeds up "the drawing process" in an application.  From now on, you will not need to draw all the objects in a scene, only the objects visible.

Functions Used:  glGetFloatv(), GetCursorPos(), SetCursorPos(), glEnable(), gluNewQuadric(), glClear(), glLoadIdentity(), glColor3ub(), glPushMatrix(), glTranslatef(), gluSphere(), glPopMatrix()
