NurbsSet should be inclusive about which nodes an author thinks can be rendered together as one smooth surface.

*	X3D4 Architecture, NURBS component, 27.4.8 NurbsSet
*	https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-CD1/Part01/components/nurbs.html#NurbsSet

 

Since X3DParametricGeometryNode includes X3DNurbsSurfaceGeometryNode, changed all three NurbsSet geometry fields from X3DNurbsSurfaceGeometryNode to X3DParametricGeometryNode.

 

NurbsSet : X3DChildNode, X3DBoundedObject {

  MFNode  [in]     addGeometry                [X3DParametricGeometryNode]

  MFNode  [in]     removeGeometry             [X3DParametricGeometryNode]

  MFNode  [in,out] geometry          []       [X3DParametricGeometryNode]

  SFNode  [in,out] metadata          NULL     [X3DMetadataObject]

  SFFloat [in,out] tessellationScale 1.0      (0,∞)

  SFVec3f []       bboxCenter        0 0 0    (-∞,∞)

  SFVec3f []       bboxSize          -1 -1 -1 [0,∞) or −1 −1 −1

}

 

This changes X3DUOM and possibly some implementations.  Comments welcome.

 

We current intend to accept this change as resolved once X3DUOM is updated.

 

all the best, Don
