.SH DESCRIPTION
\*(CbSoDirectionalLightDragger\f1 is a composite dragger. It looks like a sun with a large arrow coming out of it. The arrow can be rotated about the sun by dragging with the mouse; its orientation is given by the \*(Cbrotation\f1 field. You can also
\&drag the sun (and the arrow with it) through 3-space. The location is stored in the \*(Cbtranslation\f1 field. 
.sp
The dragger uses an \*(CbSoRotateSphericalDragger\f1 for changing the rotation. Instead of using the default spherical geometry, this dragger
\&uses an arrow shape. 
.sp
The sun is an \*(CbSoDragPointDragger\f1. Dragging it edits the \*(Cbtranslation\f1 field; conversely, if you change the \*(Cbtranslation\f1 field the sun will move to that new location, bringing the arrow with it. The sun looks and behaves
\&just like the sun in an \*(CbSoPointLightDragger\f1, as does the \*(Cbmaterial\f1 part. See the \*(CbSoPointLightDragger\f1 man page for details. 
.sp
\f2Remember:\f1 This is \f2not\f1 a light source! It just looks like one. If you want to move a light with this dragger, you can either: 
.sp
[a] Use
\&an \*(CbSoDirectionalLightManip\f1, which is subclassed from \*(CbSoLight\f1. It creates an \*(CbSoDirectionalLightDragger\f1 and uses it as the interface to change the \*(Cbdirection\f1 of its light source (see the \*(CbSoDirectionalLightManip\f1 man page). The manipulator also edits the \*(Cbmaterial\f1 part of this dragger to match the
\&color of light the manipulator is producing. However, the directional light manipulator will ignore the \*(Cbtranslation\f1 field, because a directional light has no location or translation field. So in this case the translation
\&dragger merely allows you to move the physical arrow to wherever you'd like it to be. 
.sp
[b] Put an \*(CbSoTransform\f1 under an \*(CbSoTransformSeparator\f1. Add the \*(CbSoDirectionalLight\f1 as the next child. Use a field-to-field connection between the \*(Cbrotation\f1 fields of this dragger
\&and the transform node to synchronize the light with this dragger. 
.sp
[c] Use engines to connect the \*(Cbrotation\f1 field of this dragger to the \*(Cbdirection\f1 field of an \*(CbSoDirectionalLight\f1. Use the \*(Cbrotation\f1 as input to an \*(CbSoComposeMatrix\f1 engine. Then, use an \*(CbSoTransformVec3f\f1 engine
\&to apply that matrix to (0,0,-1), the default light direction. 
.sp
You can change the parts in any instance of this dragger using \*(CbsetPart()\f1. The default part geometries are defined as resources for this \*(CbSoDirectionalLightDragger\f1 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 \*(Cb/usr/share/data/draggerDefaults/directionalLightDragger.iv\f1 into your own directory,
\&editing the file, and then setting the environment variable \*(CbSO_DRAGGER_DIR\f1 to be a path to that directory.
