public class SoTrackballDragger extends SoDragger
Striped ball you can rotate or scale uniformly by dragging with the mouse.SoTrackballDragger
is a ball wrapped in three circular stripes. The stripes are oriented like wheels that spin around the x, y, and z axes. Drag the stripes to rotate the trackball around those axes. You do not have to hit the lines; pick anywhere within the stripe's outline. To rotate the trackball freely in 3 dimensions, click the area between the stripes and then drag. An invisible but pickable sphere initiates this dragging. If the mouse is still moving when you release it, the trackball will continue to spin.Press the <Control> key to scale the trackball uniformly instead of rotating. This behavior may be disabled by setting the environment variable OIV_DISABLE_DRAGGER_CTRL_KEY to false (see
SoPreferences
).Press the <Shift> key and the user axis appears; this is a draggable axis with an extra stripe around it. Moving the mouse along the surface of the sphere drags the 'pole' of the axis. Release the <Shift> key and the user axis remains; drag the new stripe for constrained rotation around the user axis. To make the user axis disappear, press <Shift> and drag the pole to where two of other stripes intersect. This aligns the user axis with a primary axis, at which point the user axis disappears.
As you drag the trackball, it updates its
rotation
field, or itsscaleFactor
field if the <Control> key is down. As with all draggers, if you change the fields the dragger moves in response.Remember: This is not an
SoTransform
! . If you want to move other objects with this dragger, you can either:- Use an
SoTrackballManip
, which is subclassed fromSoTransform
. The manipulator creates one of these draggers and uses it as the interface to edit the manipulator's fields. (see theSoTrackballManip
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 thisSoTrackballDragger
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/trackballDragger.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:

for more information about using and customizing draggers, including code examples, using draggers in an immersive VR environment and using WYSIWYG draggers.NOTES Unlike most multi-function draggers,
SoTrackballDragger
is not a compound dragger made up of other draggers that perform its smaller tasks. This is not because it was inappropriate, but because the trackball was written before implementation of the methods that take care of synchronizing multiple child draggers. The youngerSoCenterballDragger
is similar in form to the trackball, but the centerball is a compound dragger.File format/default:

Field Detail
-
rotation
public final SoSFRotation rotation
Orientation 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.

Method Detail
-
isAnimationEnabled
public boolean isAnimationEnabled()
Returns whether spin animation is enabled.
-
setAnimationEnabled
public void setAnimationEnabled(boolean newVal)
Enables/disables spin animation. When spin animation is enabled, if the mouse is moving while you release it, the trackball will continue to spin afterwards. By default, spin animation is enabled.
-
getClassNodekitCatalog
public static SoNodekitCatalog getClassNodekitCatalog()
Returns theSoNodekitCatalog
for this class.
