DESCRIPTION

SoLight is the abstract base class for all light nodes. A light node defines an illumination source that may affect subsequent shapes in the scene graph, depending on the current lighting style. Light sources are affected by the current transformation. A light node under a separator does not affect any objects outside that separator.

You can also use a node kit to create a light; see the reference page for SoLightKit.

FIELDS

    SoSFBool    
                    
SoSFBool             on
Determines whether the source is active or inactive. When inactive, the source does not illuminate at all.

    SoSFFloat    
                    
SoSFFloat            intensity
Illumination intensity of light source. Valid values range from 0.0 (no illumination) to 1.0 (maximum illumination).

    SoSFColor    
                    
SoSFColor            color
Light source illumination color.

METHODS

    static SoType    
                    
static SoType        getClassTypeId()
Returns type identifier for this class.

ACTION BEHAVIOR

SoGLRenderAction
Activates this light (if so specified) during traversal. All shape nodes that come after this light in the scene graph are illuminated by this light.

FILE FORMAT/DEFAULTS

This is an abstract class. See the reference page of a derived class for the format and default values.
