Camera will not move in OpenGL

I am having problems with using a camera in OpenGL/freeGLUT. Here is my code:

(For some reason, when I paste the code into the code feature on this site, it gives extremely weird output.)

As far as I can tell this should rotate the camera when arrow keys are pressed - but it does nothing. It also seems that even the initial camera position is wrong. Any clue why this is?

Solution

  • The display function is only called once. You need to either set an idle function with glutIdleFunc() or tell GLUT that the display function must be called again with glutPostRedisplay().
