Detailed Description

Manipulator to transform an ROI (Region of Interest).

This class defines a manipulator to transform an ROI (Region of Interest). The manipulator is a composite of 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 SoROI::box field (and do not set the 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 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.

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

EXAMPLE

// Initialize ROI box to full volume
SoVolumeData* volData = new SoVolumeData();
. . .
SoROIManip*   roiManip = new SoROIManip();
roiManip->box.setValue( SbVec3i32(0,0,0), volData->data.getSize() - SbVec3i32(1,1,1) );
root->addChild( roiManip );

Constructor & Destructor Documentation

◆ SoROIManip()

SoROIManip::SoROIManip ( )

Constructor.

Member Function Documentation

◆ getClassTypeId()

static SoType SoROIManip::getClassTypeId ( )

static

Returns the type identifier for this class.

◆ getDragger()

SoDragger * SoROIManip::getDragger ( )

Returns the dragger node being employed by this manip.

◆ getTypeId()

virtual SoType SoROIManip::getTypeId ( ) const

virtual

Returns the type identifier for this specific instance.

Reimplemented from SoROI.

◆ replaceManip()

SbBool SoROIManip::replaceManip	(	SoPath *	p,
		SoROI *	newOne
	)		const

Replaces the tail of the path, which must be this manipulator, with the given 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.

The manipulator will not call ref() or unref() on the node which is replacing it, nor will it make any changes to field connections. The calling process is thus responsible for keeping track of its own nodes and field connections.

◆ replaceNode()

SbBool SoROIManip::replaceNode ( SoPath * p )

Replaces the tail of the path with this manipulator.

The tail of the path must be an 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 manipulator will not call ref() on the node it is replacing. 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.
