Class SFVec3d

java.lang.Object
org.web3d.x3d.jsail.fields.X3DConcreteField
org.web3d.x3d.jsail.fields.SFVec3d
All Implemented Interfaces:
SFVec3d, X3DField
public class SFVec3d extends X3DConcreteField implements SFVec3d
This utility class provides a concrete implementation corresponding to SFVec3d X3D field type.

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.
Package hint: This specification class is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI). SFVec3d is a 3-tuple triplet of SFDouble values. See GeoVRML 1.0 Recommended Practice, Section 2.3, Limitations of Single Precision. Hint: SFVec3d can be used to specify a georeferenced 3D coordinate. Warning: comma characters within singleton values do not pass strict XML validation.
