/**

|
* @class vtkLightWidget
|
||
|
|
* @brief 3D widget for showing a LightRepresentation
|
||
|
|
*
|
||
|
|
* To use this widget, one generally pairs it with a
|
||
|
|
* vtkLightRepresentation. Various options are available in the representation
|
||
|
|
* for controlling how the widget appears, and how it functions.
|
||
|
|
*
|
||
|
|
* @par Event Bindings:
|
||
|
|
* By default, the widget responds to the following VTK events (i.e., it
|
||
|
|
* watches the vtkRenderWindowInteractor for these events):
|
||
|
|
* <pre>
|
||
|
|
* Select and move the sphere to change the light position.
|
||
|
|
* Select and move the cone or the line to change the focal point.
|
||
|
|
* Right-Click and scale on the cone to change the cone angle.
|
||
|
|
* </pre>
|
||
|
|
*
|
||
|
|
* @warning
|
||
|
|
* Note that the widget can be picked even when it is "behind"
|
||
|
|
* other actors. This is an intended feature and not a bug.
|
||
|
|
*
|
||
|
|
* @warning
|
||
|
|
* This class, and vtkLightRepresentation, are second generation VTK widgets.
