Coordinate builds geometry by defining a set of 3D coordinate triplet values. Coordinate is used by IndexedFaceSet, IndexedLineSet, LineSet, PointSet, Triangle* and IndexedTriangle* nodes. Coordinate is also used by HAnimHumanoid, HAnimSegment, and various Nurbs nodes.
The Coordinate node belongs to the Rendering component and its container field is coord. It is available since X3D version 3.0 or later.
