Contour2D
Overview
Contour2D groups a set of curve segments into a composite contour. The children segments form a closed loop, with first point of first child repeated as last point of last child, and last point of each segment repeated as the first point of the next consecutive segment. The children segments are type NurbsCurve2D or ContourPolyline2D, enumerated in the consecutive order of contour topology.
The Contour2D node belongs to the NURBS component and requires at least support level 4, its default container field is trimmingContour. It is available from X3D version 3.0 or higher.

Fields
| Type | Access Type | Name | Default Value |
|---|---|---|---|
| SFNode | [in, out] | metadata | NULL |
| MFNode | [in] | addChildren | |
| MFNode | [in] | removeChildren | |
| MFNode | [in, out] | children | [ ] |
SFNode [in, out] metadata NULL [X3DMetadataObject]
Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node.
Hint
MFNode [in] addChildren
Input field addChildren.
MFNode [in] removeChildren
Input field removeChildren.
MFNode [in, out] children [ ] [NurbsCurve2D|ContourPolyline2D]
The children form a closed loop with first point of first child repeated as last point of last child, and the last point of a segment repeated as first point of the consecutive one.
Hint
- children nodes are listed in consecutive order according to topology of the contour.
Advice
Hint
- Contour2D is used as the trimmingContour field of the NurbsTrimmedSurface node.
Warning
- Contour2D is not a renderable geometry node.
