Normal

Definition :
Normal {
  exposedField MFVec3f vector  []
}
Explanation :

This node defines a set of 3D surface normal vectors to be used in the vector field of some geometry nodes (IndexedFaceSet, ElevationGrid). 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.
