void glutPostRedisplay(void); call this function when you need to redraw the screen. the display callback render will be called in the next iteration of the main loop.
void keyboard( unsigned char key, int x, int y ); process key events for user inputs (move cameras, switch rendering modes, etc.)
void mouse( int button, int state, int x, int y ); process mouse events for user inputs (rotate or zoom cameras, select or move objects, etc.)
void reshape( int w, int h ); change viewport and projection matrix when the window is resized
