All Implemented Interfaces:
SFVec4f, X3DField

public class SFVec4f extends X3DConcreteField implements SFVec4f
This utility class provides a concrete implementation corresponding to SFVec4f X3D field type.


Package hint: This specification class is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI). SFVec4f is a 4-tuple set of single-precision floating-point values, specifying a 3D homogeneous vector. Warning: comma characters within singleton values do not pass strict XML validation.
