Spotlight shaped dragger that allows you to change position, direction, and width of the beam.
SoSpotLightDragger is a composite dragger. It is shaped like a beam of light emanating from a sun-like ball. An arrow runs along the axis of the beam and extends past the end of the beam.
When you click and drag the beam, it opens and closes with an umbrella-like motion. The angle between the center and edge of the beam is stored in the angle field of this dragger; setting the angle field causes the beam to widen or narrow in response. The spotlight dragger does not use a standard dragger class to execute this motion. More details are given later in this section.
Dragging the arrow rotates it around the sun, and the beam moves with it. The arrow is an SoRotateSphericalDragger that controls the rotation field. See the reference page for SoDirectionalLightDragger, which works the same way, for details.
The sun-shape can be dragged to translate all three pieces together through 3-space. Its movement controls the translation field and works exactly as described in the reference pages for SoDirectionalLightDragger and SoPointLightDragger (which goes into more detail).
Remember: This is not a light source! It just looks like one. If you want to move a light with this dragger, you can do the following:
See the SoPointLightDragger and SoDirectionalLightDragger reference pages for other ways to control light parameters with the rotation and translation fields.
This class creates its own projector and handles mouse events to do its own dragging of the beam angle. When the mouse picks a point on the beam, that point is dragged in a circle just like in an SoRotateDiscDragger, but the plane of the disc is re-defined every time a drag is initiated. Imagine placing the metal tip of a compass at the apex of the cone and the pencil tip at the picked point. If you swing an arc through the central axis of the cone, you will be drawing the arc used to drag the beam open and closed.
The beam is opened and closed not by rotating, but by scaling. The dragger scales the beam-cone so that the height and radius change to move the picked point along the circle. Then the angle field is calculated from the height and radius.
You can change the geometry of parts in any instance of this dragger using setPart(). The default part geometries are defined as resources for this SoSpotLightDragger class. They are detailed below in the DRAGGER RESOURCE section. You can make your program use different default resources for the parts by copying the file $OIVHOME/data/draggerDefaults/spotLightDragger.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.
