public class SFMatrix4f
extends X3DConcreteField
implements SFMatrix4f
This utility class provides a concrete implementation corresponding to SFMatrix4f X3D field type.


Package hint: This specification class is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI). SFMatrix4f specifies a 4x4 matrix of single-precision floating point numbers, organized in row-major fashion. Warning: comma characters within singleton values do not pass strict XML validation.
