All Superinterfaces:
X3DNode, X3DNurbsControlCurveNode
All Known Implementing Classes:
NurbsCurve2D
public interface NurbsCurve2D
extends X3DNurbsControlCurveNode
NurbsCurve2D defines a trimming segment that is part of a trimming contour in the u-v domain of a surface.

X3D node tooltip: [X3DNurbsControlCurveNode] NurbsCurve2D defines a trimming segment that is part of a trimming contour in the u-v domain of a surface. NurbsCurve2D and ContourPolyline2D nodes that together form a closed contour, defined in the u-v parametric space of a NURBS surface, may be used as children in a Contour2D node.
  • Warning: NurbsCurve2D is not a renderable geometry node.

Package hint: This interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).
