Detailed Description

Node that defines surface normals for shapes.

This node defines a set of 3D surface normal vectors to be used in the vector field of some geometry nodes (SoVRMLIndexedFaceSet, SoVRMLElevationGrid). This node contains one multiple-valued field that contains the normal vectors. Normals should be unit-length or results are undefined. Default normals are generated if none are given.

NOTE: This class does not exist in Open Inventor 10.0 and later.

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 .

This node defines a set of 3D surface normal vectors to be used in the vector field of some geometry nodes (SoVRMLIndexedFaceSet, SoVRMLElevationGrid). This node contains one multiple-valued field that contains the normal vectors. Normals should be unit-length or results are undefined.

To save network bandwidth, it is expected that implementations will be able to automatically generate appropriate normals if none are given. However, the results will vary from implementation to implementation.
