public class SoPointLightDragger extends SoDragger
Sun-shaped icon you can translate in 3D by dragging with the mouse. SoPointLightDragger is a dragger that looks like a point light source, can be translated in three directions, and has a translation field that always reflects its position in local space. The point light dragger also has a special material part which can be used to make it take on the color of a light source.

Remember: This is not a light source! It just looks like one. If you want to move a light with this dragger, you can either:

  • Use an SoPointLightManip, which is subclassed from SoLight. It creates one of these draggers and uses it as the interface to change the location of its light source (see the SoPointLightManip reference page). The manipulator also edits the material part of this dragger to match the color of light the manipulator is producing.
  • Use a field-to-field connection to connect the location of a light source from this dragger's translation field.

This dragger contains an SoDragPointDragger, which you drag through 3-space using an integrated set of linear and planar draggers. (For detailed information on how to use SoDragPointDragger, see its reference page.) The point light dragger sets the planar translation parts of this dragPoint dragger with a new default that looks like a shining sun emanating rays of light (okay, so use your imagination).

By changing the material part you can change the color of the sun shape, because the default part contains no SoMaterial nodes. This fact enables the SoPointLightManip (not the dragger, the manipulator) to color its dragger to match the color of the light it is emanating. Recall that a point light manip is derived from SoLight and creates a point light dragger to provide an interface and geometrical presence on screen. The manipulator also has a color field; when the light color changes, it changes the material part of its dragger so that they match.

You can change the parts in any instance of this dragger using setPart().

The default part geometries are defined as resources for this SoPointLightDragger 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/pointLightDragger.iv into your own directory, editing the file, and then setting the environment variable SO_DRAGGER_DIR to be a path to that directory.

See SoDragger for more information about using and customizing draggers, including code examples, using draggers in an immersive VR environment and using WYSIWYG draggers.
