DESCRIPTION

62       SoLight  is  the  abstract base class for all light nodes. A light node
63       defines an illumination source that may affect subsequent shapes in the
64       scene graph, depending on the current lighting style. Light sources are
65       affected by the current transformation. A light node under a  separator
66       does not affect any objects outside that separator.
67
68       You  can  also use a node kit to create a light; see the reference page
69       for SoLightKit.

FIELDS

72     SoSFBool            on
73          Determines whether the source is active or inactive. When  inactive,
74          the source does not illuminate at all.
75
76     SoSFFloat           intensity
77          Illumination  intensity of light source. Valid values range from 0.0
78          (no illumination) to 1.0 (maximum illumination).
79
80     SoSFColor           color
81          Light source illumination color.

METHODS

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

ACTION BEHAVIOR

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

FILE FORMAT/DEFAULTS

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