MedicalHelperOrientView Method |
Adjusts the camera to view a slice or volume along the specified axis.
The camera is rotated to give the conventional orientation for the specified axis.
If the volume data is specified, then viewAll() is called to center the volume in
the view volume.
If the camera is an SoOrthographicCamera (the usual case for viewing a slice) and
the volume data node is specified, then the camera (specifically the view volume
height) is adjusted to make the slice image fill the viewport. This is convenient
because the viewAll() method gives a very loose fit around the slice image.
If the camera is an SoPerspectiveCamera (commonly used for viewing a 3D volume)
or the volume data node is specified, then ViewAll() is called, but no
additional adjustment is done to the camera. 'slack' is ignored in this case.
Axial -> "Feet" view.
Coronal -> "Anterior" view.
Sagittal -> "Left" view.
For a 3D volume rendering view, typically specify the Coronal axis.

Parameters
- axis
- Type: OIV.Medical.HelpersMedicalHelperAxis
Axial, Coronal or Sagittal - camera
- Type: OIV.Inventor.NodesSoCamera
The camera node that will be modified (fails if null). - volume (Optional)
