New page

Matlab options for navigating 3d scenes include:
* rotation of viewing perspective
* dragging the scene (''pan'' action)
* zooming in and out.

The native system to switch among them is however limited, as they force the user to move the cursor to the toolbar to select a different icon. ''Dynamo'' extends the native system, associating the viewing actions to different combinations of keys and mouse actions.

== Activating the 3d mouse ==

The 3d mouse can be activated in any [[ Programmatic_depiction_of_objects_in_tomograms#Matlab_axes | Matlab axis]].

<tt>mbgraph.cursors.setMouse3d([]);</tt>

or

<tt>mbgraph.cursors.setMouse3d(haxis);</tt>

for a [[Programmatic_depiction_of_objects_in_tomograms#Basic_tool:_graphic_handles | handle <tt>haxis</tt>]]. Once the order is launched, the axis will recognize the controls:

* rotation: main click on the scene and move the mouse.
* dragging: middle click on the scene and move the mouse keeping mouse button pressed.
* zooming: scroll mouse wheel.

== 3d mouse in <tt>tomoslice</tt> ==

Inside [[dtmslice]] the controls of the 3d mouse are slightly different, to avoid interference with <tt>dtmslice</tt> controls.
* rotation: keep <tt>[control]</tt> key pressed, main click on the scene and move the mouse.
* dragging: keep <tt>[shift]</tt> key pressed, main click on the scene and move the mouse.
* zooming: scroll mouse wheel while keeping <tt>[control]</tt> or <tt>[shift]</tt> key pressed.
In <tt>dtmslice</tt> the 3d mouse gets activated also when the click is not performed on an empty region of the axis.
