org.web3d.x3d.jsail.fields.MFVec3d

All Implemented Interfaces:

MField, MFVec3d, X3DField

public class MFVec3d
extends X3DConcreteField
implements MFVec3d

This utility class provides a concrete implementation corresponding to MFVec3d 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). MFVec3d is an array of SFVec3d values. Individual singleton SFVec3d array values are optionally separated by commas in XML syntax. Original rationale for inclusion: GeoVRML 1.0 Recommended Practice, Section 2.3, Limitations of Single Precision. Hint: MFVec3d can be used to specify a list of georeferenced 3D coordinates.
