I drew a scene and then tried to move around in it in real time, so I put a “switch” and then a bunch of “cases” for keys and let the glutKeyboradFunc do the work, using gluLookAt, changing the values of variables in it. It works pretty bad. First of all, glut works only with ASCII keys, which exclude arrows. secondly, you have to put gluLookAt into IdleFunc for constant update. Is there a better way to move around in real time, or do I have to use MFC?
