WebNote that the eye position is 5.0 units away from the look at point. This is important, because a distance of 5.0 units in front of the eye is in the middle of the Z volume that the Projection transform defines. If the gluLookAt() call had placed the eye at (0.0, 0.0, 1.0), it would produce a distance of 1.0 to the origin.

But this code is useless, since it still rotates the object around the edge and not the center ... WebOct 10, 2004 · I'm not sure what you want to do. in the mouse function, you want to iterate the angles for both arms -- right now, only one theta[ID] is updated at one time. duplicate the lines, and move the second arm angle at the same time. in the display function, you could have it automatically update the arm angle(s) each frame, maybe one degree per frame. …
