public class SoLight extends SoNode
SoLightis 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
Lighting is enabled by default (default model is PHONG). When lighting is enabled, there must be light nodes (e.g.
SoDirectionalLight) in the scene graph for objects to be easily visible. When using the Open Inventor viewer classes (e.g. SoWinExaminerViewer), the viewer will create a "headlight" (directional light attached to the camera) if no other light nodes exist when setSceneGraph() is called.
By default OpenGL only computes lighting for the "front" face of geometry, so the back face of the geometry will be dark. The front face is determined by the normal vector, if specified, or by the vertex ordering (see
SoShapeHints) if normals are computed by Open Inventor. To enable "two sided" lighting (lighting both front and back faces) see
This is an abstract class. See the reference page of a derived class for the format and default values.
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.
