Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
Public methodFieldsAreEqual

Returns true if this object's fields are exactly equal to fc's fields.

(Inherited from SoFieldContainer.)

Returns a list of fields, including the eventIn's and eventOut's.

(Inherited from SoFieldContainer.)
Public methodGetAlternateRep

This method is called by actions to allow the node to provide an "alternate representation" when appropriate (typically depending on the action type).

Returns a the field of this object whose name is fieldName.

(Inherited from SoFieldContainer.)
Public methodGetFieldName

Returns the name of the given field in the fieldName argument.

(Inherited from SoFieldContainer.)

Remarks

This class defines a manipulator to transform an ROI (Region of Interest). The manipulator is a composite of OIV.LDM.Nodes.SoROI and an OIV.Inventor.Draggers.SoTabBoxDragger that allows the user to interactively move and resize the ROI.

To define a simple ROI, set the limits of the ROI in the OIV.LDM.Nodes.SoROI.box field (and do not set the OIV.LDM.Nodes.SoROI.subVolume field). The same result is obtained by setting the 'box' and 'subVolume' fields to the same value, but this is not necessary. But note that, like OIV.LDM.Nodes.SoROI, the default ROI box is not automatically the full volume. You must initialize the ROI box to something, for example the volume dimensions minus one. See OIV.LDM.Nodes.SoROI for more details.

Note: The edge color of the embedded dragger is modified, i.e. is not the same as the default edge color in OIV.Inventor.Draggers.SoTabBoxDragger.

EXAMPLE

Copy
SoVolumeData volData = new SoVolumeData();
. . .
SoROIManip roiManip = new SoROIManip();
roiManip.box.SetValue( new SbVec3i32(0, 0, 0), volData.data.GetSize() - new SbVec3i32(1, 1, 1));
root.AddChild( roiManip );

FILE FORMAT/DEFAULT

ROIManip {
subVolume 0 0 0 0 0 0
box 0 0 0 1 1 1
flags 7
relative false
boxOn true
constrained false
}
