Detailed Description
Node representing a directional light source.
The SoVRMLDirectionalLight node defines a directional light source that illuminates along rays parallel to a given 3-dimensional vector.
NOTE: This class does not exist in Open Inventor 10.0 and later.The direction field specifies the direction vector within the local coordinate system that the light illuminates in. Light is emitted along parallel rays from an infinite distance away. A directional light source illuminates only the objects in its enclosing parent group. The light may illuminate everything within this coordinate system, including all children and descendants of its parent group. The accumulated transformations of the parent nodes affect the light.
VRML97 SPECIFICATION
- This section describes the expected behavior of the node in a conforming VRML97 browser application. In some cases, the application is responsible for implementing portions of the expected behavior. Open Inventor viewer classes and IVF classes implement some of the application behaviors.
This section may reference portions of the VRML97 specification that are not present in this help file. The complete VRML97 spec is available at http://www.web3d.org .
The SoVRMLDirectionalLight node defines a directional light source that illuminates along rays parallel to a given 3-dimensional vector. See "Concepts - Lights" for a definition of the ambientIntensity , color , intensity , and on fields.
