== Main View ==
Here below is displayed an example of 3D interaction on a selected Mesh in OpticalRevEngDental.
{{Screenshot|3DView.PNG}}
It is possible to interact with the 3D View using the mouse and the keyboard, the context menu, the view menu and the view toolbar.
=== Mouse Interaction ===
The user can interact with the orientation of the 3D object through either the use of the mouse or more specific tools that can be selected in the ''Context menu''.
Here below, find the list of the provided mouse/keyboard combinations:
<!--T:27-->
* {{Inline button|Mouse_middle.png}} + {{Inline button|Mouse_right.png}} or {{Inline button|Key_alt.png}} + {{Inline button|Mouse_right.png}}: pan the camera in 2D
* {{Inline button|Mouse_right.png}}: freely rotate the camera around the 3D Object
* {{Inline button|Key_ctrl.png}} + {{Inline button|Mouse_middle.png}}: rotate the camera restricted to the Y axis of the 3D View
* {{Inline button|Key_alt.png}} + {{Inline button|Mouse_middle.png}}: rotate the camera restricted to the X axis of the 3D View
* {{Inline button|Key_shift.png}} + {{Inline button|Mouse_middle.png}}: rotate the camera restricted to the Z axis of the 3D View
* {{Inline button|Mouse_middle_rotating.png}}: change Zoom
* {{Inline button|Mouse_right.png}} : enter the context menu
* {{Inline button|Key_ctrl.png}} + {{Inline button|Mouse_right.png}}: change the position of the light source in the 3D View
* {{Inline button|Mouse_left.png}} : use the current tool (E.g. Rectangular Selection, Hole Filling, etc.)
* {{Inline button|Key_ctrl.png}} + {{Inline button|Mouse_left.png}} : invert the current tool if available (E.g. Deselect points instead of Select points, etc.)
* {{Inline button|Key_shift.png}} + Number from 1 to 7 : change the 3D View to one of the default positions (E.g. Frontal, Back, Top, etc.)
=== Context Menu and View Menu ===
The view menu and the 3D View context menu contain some tools that can be used to interact with the 3D View.

<!--T:31-->
* '''Frame All''' ({{Inline button|Key_ctrl.png}} + A) : the 3D camera will move to show, on the screen, all the current selected 3D Objects
* '''Rotation On View''' : if this option is enabled, the rotation will ignore the current selected 3D Objects; if it is disabled, the center of the rotation will be the baricenter of the selected 3D Objects
* '''Area Frame Tool''': this tool allows to draw with {{Inline button|Mouse_left.png}} a rectangle. The rectangle will become the new camera view.
* '''Center View''' ({{Inline button|Key_ctrl.png}} + P) : the currently selected 3D Objects are moved at the center of the screen without changing their Zoom
* '''Standard Poses''' : sub-menu to apply default 3D views:
** '''Front''' ( {{Inline button|Key_alt.png}} + 1)
** '''Back''' ( {{Inline button|Key_alt.png}} + 2)
** '''Top''' ( {{Inline button|Key_alt.png}} + 3)
** '''Bottom''' ( {{Inline button|Key_alt.png}} + 4)
** '''Left''' ( {{Inline button|Key_alt.png}} + 5)
** '''Right''' ( {{Inline button|Key_alt.png}} + 6)

* '''Points''': the number of points of the currently selected objects
* '''Faces''': the number of faces, available only for triangle meshes
* '''Selected''': the number of selected points/faces of the currently selected objects
* '''Size and Position''': the minimum/maximum coordinates of the volume of the currently selected objects, and their size in every direction
