glutKeyboardFunc(void (*func)(unsigned char key, int x, int y))     sets key processing routine     x and y are mouse coordinates when the key 'key' was pressed     see glutGetModifiers for state of modifier keys (eg. ctrl,...) glutSpecialFunc(void (*func)(int key, int x, int y));   glutMouseFunc(void (*func)(int button, int state, int x, int y))     mouse function callback     button: GLUT_LEFT_BUTTON, GLUT_MIDDLE_BUTTON, GLUT_RIGHT_BUTTON     state: GLUT_UP, GLUT_DOWN     x, y: mouse coordinates
