DESCRIPTION
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:
[a] 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.
[b] 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 /usr/share/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.
