Class java.media.j3d.PhysicalBody 

java.lang.Object
   |
   +----java.media.j3d.PhysicalBody
public class PhysicalBody
extends Object
This object contains a specification of the user's head. Attributes of this object are defined in the head coordinate system. The orgin is defined to be halfway between the left and right eye in the plane of the face. The x-axis extends to the right (of the head looking out from the head). The y-axis extends up. The z-axis extends to the rear of the head.

Constructor Index

o PhysicalBody()
Constructs and initializes a default User head object.
o PhysicalBody(Point3d, Point3d)
Constructs and initializes a User head object from its parameters.
o PhysicalBody(Point3d, Point3d, Point3d, Point3d)
Constructs and initializes a User head object from its parameters.
