Detailed Description

The SoRotateSphericalDragger class is for rotating geometry in any direction.

Here's how the dragger looks with its default geometry in the inactive state:

rotatespherical.png

Use an instance of this dragger class in your scenegraph to let the end-users of your application rotate geometry freely in any direction.

For the initial dragger orientation and the dragger geometry positioning itself, use some kind of transformation node in your scenegraph, as usual.


Constructor & Destructor Documentation

SoRotateSphericalDragger::SoRotateSphericalDragger ( void  )

Default constructor, sets up the dragger nodekit catalog with the interaction and feedback geometry.

Node kit structure (new entries versus parent class marked with arrow prefix):

  CLASS SoRotateSphericalDragger
  -->"this"
        "callbackList"
        "topSeparator"
           "motionMatrix"
           "geomSeparator"
  -->         "rotatorSwitch"
  -->            "rotator"
  -->            "rotatorActive"
  -->         "feedbackSwitch"
  -->            "feedback"
  -->            "feedbackActive"
  

(See SoBaseKit::printDiagram() for information about the output formatting.)

Member Function Documentation

void SoRotateSphericalDragger::initClass ( void  ) [static]

Initializes type system for this dragger class.

Application programmers should usually not have to invoke this method, see documentation of SoInteraction::init().

Reimplemented from SoDragger.

void SoRotateSphericalDragger::setProjector ( SbSphereProjector p)

Replace the default sphere projection strategy. You may want to do this if you change the dragger geometry, for instance.

The default projection is an SbSpherePlaneProjector.

See also:
SbSphereSectionProjector, SbSphereSheetProjector

References sphereProj, and userProj.

const SbSphereProjector * SoRotateSphericalDragger::getProjector ( void  ) const

Returns projector instance used for converting from user interaction dragger movements to 3D dragger re-orientation.

See also:
setProjector()

References sphereProj.

SbBool SoRotateSphericalDragger::setUpConnections ( SbBool  onoff,
SbBool  doitalways = FALSE 
) [protected, virtual]

Sets up all internal connections for instances of this class.

(This method will usually not be of interest to the application programmer, unless you want to extend the library with new custom nodekits or dragger classes. If so, see the SoBaseKit class documentation.)

Reimplemented from SoInteractionKit.

References SoFieldSensor::attach(), SoBaseKit::connectionsSetUp, SoFieldSensor::detach(), fieldSensor, fieldSensorCB(), SoFieldSensor::getAttachedField(), rotation, and SoInteractionKit::setUpConnections().

Referenced by SoRotateSphericalDragger().

void SoRotateSphericalDragger::copyContents ( const SoFieldContainer from,
SbBool  copyconnections 
) [protected, virtual]

Makes a deep copy of all data of from into this instance, except external scenegraph references if copyconnections is FALSE.

This is the protected method that should be overridden by extension node / engine / dragger / whatever subclasses which needs to account for internal data that are not handled automatically.

For copying nodes from application code, you should not invoke this function directly, but rather call the SoNode::copy() function:

  SoNode * mynewnode = templatenode->copy();

The same also goes for engines.

Make sure that when you override the copyContents() method in your extension class that you also make it call upwards to it's parent superclass in the inheritance hierarchy, as copyContents() in for instance SoNode and SoFieldContainer does important work. It should go something like this:

  void
  MyCoinExtensionNode::copyContents(const SoFieldContainer * from,
                                    SbBool copyconnections)
  {
    // let parent superclasses do their thing (copy fields, copy
    // instance name, etc etc)
    SoNode::copyContents(from, copyconnections);

    // [..then copy internal data..]
  }

Reimplemented from SoInteractionKit.

Member Data Documentation

This field is continuously updated to contain the rotation of the current direction vector of the dragger.

The application programmer using this dragger in his scenegraph should connect the relevant node fields in the scene to this field to make them follow the dragger orientation.
