Package org.web3d.x3d.sai.NURBS

Interface Contour2D

All Superinterfaces:

X3DNode

All Known Implementing Classes:

Contour2D

public interface Contour2D
extends X3DNode

Contour2D groups a set of curve segments into a composite contour.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. X3D node tooltip: [X3DNode] 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. Warning: Contour2D is not a renderable geometry node. Hint: Contour2D is used as the trimmingContour field of the NurbsTrimmedSurface node. *


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

Method Details

getChildren

X3DNode[] getChildren()

Provide array of org.web3d.x3d.sai.Core.X3DNode results (using an array consisting of properly typed nodes or ProtoInstances) with acceptable node types limited to NurbsCurve2D|ContourPolyline2D, from inputOutput MFNode field children.

Tooltip: [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. *


Warning: according to X3D Unified Object Model (X3DUOM), acceptable node types are limited to NurbsCurve2D|ContourPolyline2D.

Returns:

value of children field

See Also:

• NurbsCurve2D
• ContourPolyline2D

setChildren

Contour2D setChildren(X3DNode[] newValue)

Accessor method to assign org.web3d.x3d.sai.Core.X3DNode array (using an array consisting of properly typed nodes or ProtoInstances) to inputOutput MFNode field children.

Tooltip: [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. *


Note: according to X3D Unified Object Model (X3DUOM), acceptable node types are limited to NurbsCurve2D|ContourPolyline2D.

Parameters:

newValue - is new value for the children field.

Returns:

Contour2D - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

addChildren

void addChildren(X3DNode[] newValue)

Add array of children nodes to array of existing nodes (if any).

Note: according to X3D Unified Object Model (X3DUOM), acceptable node types are limited to NurbsCurve2D|ContourPolyline2D.

Parameters:

newValue - is new value array to be appended the children field.

setChildren

void setChildren(X3DNode newValue)

Set single children node, replacing prior array of existing nodes (if any).

Parameters:

newValue - is new node for the children field

getMetadata

X3DMetadataObject getMetadata()

Provide org.web3d.x3d.sai.Core.X3DMetadataObject instance (using a properly typed node) from inputOutput SFNode field metadata.

Tooltip: [X3DMetadataObject] Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node. Hint: X3D Architecture 7.2.4 Metadata <a href="https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS//Part01/components/core.html#Metadata" target="_blank">https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS//Part01/components/core.html#Metadata</a> *

Specified by:

getMetadata in interface X3DNode

Returns:

value of metadata field

setMetadata

Contour2D setMetadata(X3DMetadataObject newValue)

Accessor method to assign org.web3d.x3d.sai.Core.X3DMetadataObject instance (using a properly typed node) to inputOutput SFNode field metadata.

Tooltip: [X3DMetadataObject] Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node. Hint: X3D Architecture 7.2.4 Metadata <a href="https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS//Part01/components/core.html#Metadata" target="_blank">https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS//Part01/components/core.html#Metadata</a> *

Specified by:

setMetadata in interface X3DNode

Parameters:

newValue - is new value for the metadata field.

Returns:

Contour2D - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
