Is there a way to turn off this restriction? bump - I just ran into this problem too and would like to know how to lift this restriction on rotation.

Would you have an example?

Would you have an example? Just plot anything in 3D (use 'peaks' or 'sphere' for example), then try to rotate the plot with the mouse, continuously, for more than 180 degrees, about any axis in the x-y plane. Any vertical mouse cursor motion will illustrate the issue. In Matlab, the z-axis is special - you can rotate indefinitely about the z-axis. Any other axis "hits a wall", and stops you at elevation angle equal to 90 or -90. Example of unrestricted mouse rotation UI: http://mathworld.wolfram.com/Sphere.html . There may be a good reason for the restriction in Matlab, but I personally would rather not have it the majority of the time.

From the menu select view->camera toolbar. Then click the "orbit camera" icon and the "principal axis z" icon. Vertical mouse motion will now spin the figure until you run into the top or bottom edge of your monitor. Ken

Looks like this can be accomplished directly with cameratoolbar('setmodeGUI', 'orbit')
