Interface Circle2D

All Superinterfaces:

X3DGeometryNode, X3DNode

All Known Implementing Classes:

Circle2D

public interface Circle2D
extends X3DGeometryNode

Circle2D is a geometry node that defines a linear X-Y circle with center (0,0) in X-Y plane.

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: [X3DGeometryNode] Circle2D is a geometry node that defines a linear X-Y circle with center (0,0) in X-Y plane. Hint: insert a Shape node before adding geometry or Appearance.

Method Details

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 X3DGeometryNode

Specified by:

getMetadata in interface X3DNode

Returns:

value of metadata field

setMetadata

Circle2D 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 X3DGeometryNode

Specified by:

setMetadata in interface X3DNode

Parameters:

newValue - is new value for the metadata field.

Returns:

Circle2D - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

• X3D Scene Authoring Hints: Metadata Nodes

getRadius

float getRadius()

Provide float value within allowed range of (0,infinity) from initializeOnly SFFloat field named radius.

Tooltip: (0,+infinity) circle radius. Warning: simple-geometry dimensions are initializeOnly and cannot be changed after initial creation, avoiding the need for potentially expensive tessellation at run time. Hint: for size animation, modify the scale of a parent/ancestor Transform node instead. *

Returns:

value of radius field

setRadius

Circle2D setRadius(float newValue)

Accessor method to assign float value to initializeOnly SFFloat field named radius.

Tooltip: (0,+infinity) circle radius. Warning: simple-geometry dimensions are initializeOnly and cannot be changed after initial creation, avoiding the need for potentially expensive tessellation at run time. Hint: for size animation, modify the scale of a parent/ancestor Transform node instead. *

Parameters:

newValue - is new value for the radius field.

Returns:

Circle2D - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
