Class: VolumeViewport3D
An object representing a 3-dimensional volume viewport. VolumeViewport3Ds are used to render 3D volumes in their entirety, and not just load a single slice at a time.
For setting volumes on viewports you need to use addVolumesToViewports which will add volumes to the specified viewports.

getViewPresentation()
getViewPresentation(
viewPresSel):ViewPresentation
Gets a view presentation information specifying HOW a viewport displays something, but not what is being displayed. See getViewReference to get information on WHAT is being displayed.
This is intended to have information on how an image is presented to the user, without specifying what image s displayed. All of this information is available externally, but this method combines the parts of this that are appropriate for remember or applying to other views, without necessarily needing to know what all the attributes are. That differs from methods like getCamera which fetch exact view details that are not likely to be identical between viewports as they change sizes or apply to different images.
Note that the results of this can be used on different viewports, for example, the pan values can be applied to a volume viewport showing a CT, and a stack viewport showing an ultrasound.
The selector allows choosing which view presentation attributes to return.
Some default values are available from Viewport.CameraViewPresentation and
Viewport.TransferViewPresentation
Parameters

select which attributes to display.
Returns
Inherited from

getViewReferenceId()
getViewReferenceId(
specifier):string
For a volume viewport, the reference id will be a URN starting with
volumeId:<volumeId>, followed by additional arguments to specify
the view orientation. This will end up being a unique string that
identifies the view reference being shown. It is different from the
view reference in that the values are all incorporated into a string to
allow using it as a parameter key.

setDisplayAreaFit()
protectedsetDisplayAreaFit(displayArea):void
This applies a display area with a fit of the provided area to the available area. The zoom level is controlled by the imageArea parameter, which is a pair of percentage width in the horizontal and vertical dimension is scaled to fit the displayable area. Both values are taken into account, and the scaling is set so that both fractions of the image area are visible.
The panning is controlled by the imageCanvasPoint, which has two values, teh imagePoint and the canvasPoint. They are fractional values of the image and canvas respectively, with the panning set to display the image pixel at the given fraction on top of the canvas at the given percentage. The default points are 0.5.
For example, if the zoom level is [2,1], then the image is displayed such that at least twice the width is visible, and the height is visible. That will result in the image width being black, divided up on the left and right according to the imageCanvasPoint
Then, if the imagePoint is [1,0] and the canvas point is [1,0], then the right most edge of the image, at the top of the image, will be displayed at the right most edge of the canvas, at the top.
Parameters
• displayArea: DisplayArea

Parameters
• displayArea: DisplayArea
display area to set
- displayArea.scale - the number of physical pixels to display
each image pixel in. Values
