Purpose¶

SoDirectionalLightDragger 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 rotation field. You can also drag the sun (and the arrow with it) through 3-space. The location is stored in the translation field.

The dragger uses an SoRotateSphericalDragger for changing the Rotation. Instead of using the default spherical geometry, this dragger uses an arrow shape.

The sun is an SoDragPointDragger. Dragging it edits the Translation field; conversely, if you change the Translation 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 SoPointLightDragger, as does the material part.

Parameter Fields¶

Visible Fields¶

Is Active¶

name: isActive, type: Bool, persistent: no¶: TRUE when mouse is down and dragging, else FALSE.

Translation¶

name: translation, type: Vector3, default: 0 0 0¶: The position of the dragger.

Rotation¶

name: rotation, type: Rotation, default: 0 0 1 0¶: Orientation of the dragger. Three lines along the x, y, and z axes form the central star shape, which you can drag with the mouse to rotate the dragger.

Hidden Fields¶

enable¶

name: enable, type: Bool, default: TRUE¶
