Update a 3D graph without resetting viewpoint?

I generate a 3D graph. My user, using the mouse, rotates it and changes the viewpoint. Then the user modifies a parameter and I regenerate the graph. The graph snaps back to its original, default 3D viewpoint. I don't want this! It would be much more informative to the user if the graph changed in place, with no change of viewpoint. Is this possible?

Yes. You can store the axes view and later restore it to the stored value after updating the plot. See view.
Alternatively, update the plot using low-level functionality (e.g., set(h,'XData',x,'YData',y,'ZData',z)) rather than high-level functions (e.g., plot3(x,y,z)), because low-level functions don't affect the axes, including the axes view.
