public class SoRotateSphericalDragger
extends SoDragger

Object you can rotate about a spherical surface by dragging with the mouse. SoRotateSphericalDragger is a simple dragger that rotates freely in all directions. The feel of the rotation is as if you were rolling a ball. The center of rotation is the origin of the local space, determined by the dragger's location in the scene graph. Transformation nodes placed before it will affect both the dragger and the direction of motion.

This node has a rotation field which always reflects its orientation in local space. If you set the field, the dragger will rotate accordingly. You can also connect fields of other nodes or engines from this one to make them follow the dragger's orientation.

This dragger contains four parts, rotator , rotatorActive , feedback , and feedbackActive .

Each of these is set by default from a resource described in the Dragger Resources section of the online reference page for this class. You can change the parts in any instance of this dragger using setPart().

You can make your program use different default resources for the parts by copying the file $OIVHOME/data/draggerDefaults/rotateSphericalDragger.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.

Constructor Detail

SoRotateSphericalDragger

public SoRotateSphericalDragger()

Constructor.

Method Detail

setProjector

public void setProjector(SbSphereProjector p)

Sets a different sphere projector. See the SbSphereProjector reference pages to find out how each kind affects the feel of your dragger's motion. The default uses an SbSpherePlaneProjector.

Passing in NULL will cause the default type of projector to be used. Any projector you pass in will be deleted by this dragger when this dragger is deleted. Note that the center and radius of the sphere are determined by the dragger, based on the origin of the local space and the distance between the initial mouse click and that origin.

getClassNodekitCatalog

public static SoNodekitCatalog getClassNodekitCatalog()

Returns the SoNodekitCatalog for this class.

getProjector

public SbSphereProjector getProjector()

Gets the sphere projector.
