public class SoROIManip extends SoROI
SoROI and an 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 box field (and do not set the 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 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 SoROI for more details.
// Initialize ROI box to full volume SoVolumeData volData = new SoVolumeData(); . . . SoROIManip roiManip = new SoROIManip(); roiManip.box.setValue( new SbVec3i32(0, 0, 0), volData.data.getSize().minus( new SbVec3i32(1, 1, 1))); root.addChild( roiManip );

public boolean replaceNode(SoPath p)
SoROI node (or subclass thereof). If the path has a nodekit, this will try to use setPart() to insert the manipulator. Otherwise, the manipulator requires that the next-to-last node in the path chain be a group.
The field values from the ROI node will be copied to this manipulator, and the ROI node will be replaced.
The old node will disappear if it has no references other than from the input path p and its parent, since this manipulator will be replacing it in both of those places. Nor will the manipulator make any changes to field connections of the old node. The calling process is thus responsible for keeping track of its own nodes and field connections.
public boolean replaceManip(SoPath p, SoROI newOne)
SoROI node.
If the path has a nodekit, this will try to use setPart() to insert the new node. Otherwise, the manipulator requires that the next-to-last node in the path chain be a group.
The field values from the manipulator will be copied to the ROI node, and the manipulator will be replaced.
It will not make any changes to field connections. The calling process is thus responsible for keeping track of its own nodes and field connections.
