public class SoTransformBoxDragger
extends SoDragger

Box-like object you scale, rotate, and translate by dragging with the mouse. SoTransformBoxDragger is a composite dragger shaped like a box with small cubes at the corners. Click and drag any of these cubes to scale the box uniformly. Drag any edge of the box to rotate the whole dragger about its center, along an axis parallel to that edge. Pick any face of the box for 2D translation in the plane of that face.

Although the box looks just about like a wireframe cube, it is composed of many different simple draggers arranged in a composite assembly. When one part is dragged, the transformBox makes sure they all move together. Each of the parts of the box is a different dragger with the default geometry changed. The faces of the box are SoTranslate2Draggers, the edges are SoRotateCylindricalDraggers, and the cubes are an SoScaleUniformDragger. Drag them and the dragger will update its translation, rotation and scaleFactor fields to reflect the changes. As with all draggers, if you change the fields the dragger will move to match the new settings.

Remember: This is not an SoTransform ! . If you want to move other objects with this dragger, you can either:

• Use an SoTransformBoxManip, which is subclassed from SoTransform. It creates one of these draggers and uses it as the interface to change its fields. (see the SoTransformBoxManip reference page).
• Use field-to-field connections to connect the fields of this dragger to those of any SoTransformation node.

You can change the parts in any instance of this dragger using setPart(). The default part geometries are defined as resources for this SoTransformBoxDragger class. They are detailed in the Dragger Resources section of the online reference page for this class. You can make your program use different default resources for the parts by copying the file $OIVHOME/data/draggerDefaults/transformBoxDragger.iv into your own directory, editing the file, and then setting the environment variable SO_DRAGGER_DIR to be a path to that directory.

This dragger has both a default and a WYSIWYG version:

Field Detail

rotation

public final SoSFRotation rotation

Orientation of the dragger.

translation

public final SoSFVec3f translation

Position of the dragger.

scaleFactor

public final SoSFVec3f scaleFactor

Scale of the dragger. Note: The dragger will always scale uniformly in all 3 dimensions, using the highest value in the scaleFactor field. E.g. (10, 1, 1) is equivalent to (10, 10, 10). This behavior is consistent with scaling the dragger in user interactions because the scaling component of the dragger is an SoScaleUniformDragger.
