All Implemented Interfaces:
SFRotation, X3DField

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


Package hint: This specification class is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI). SFRotation is an axis-angle 4-tuple, indicating X-Y-Z direction axis plus angle orientation about that axis. The first three values specify a normalized axis vector about which the rotation takes place, so the first three values shall be within the range [-1..+1] in order to represent a normalized unit vector. The fourth value specifies the amount of right-handed rotation about that axis in radians. Warning: comma characters within singleton values do not pass strict XML validation.
