Normal
Normal defines a set of 3D surface-normal vectors that apply either to a sibling Coordinate/CoordinateDouble node, or else to a parent ElevationGrid node. Normal values are perpendicular directions that are used per-polygon or per-vertex when computing lighting and shading.
The Normal node belongs to the Rendering component and its container field is normal. It is available since X3D version 3.0 or later.
Fields
SFNode [in, out] metadata NULL [X3DMetadataObject]
Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.
MFVec3f [in, out] vector [ ] [-1,1]
Set of unit-length normal vectors, corresponding to indexed polygons or vertices.
