TPendulum

public class TPhysObject

extends TEntityList3D

An object that adds physical quantities to TEntityList3D. It is really not complete enough and should really be extended with more variables and functionality. It's main purpose at this moment is to be able to rotate an object quite easily around a fixed axis, and to track the position in the global coordinate system of certain points (fixed in the objects local coordinate space).

Field Summary

static int	GLOBAL Used to tell a method to use global coordinates.
static int	LOCAL Used to tell a method to use local coordinates.
double	Mass The mass of the object
(package private) static int	MAXPICKPOINTS The maximum amount of fixed points it should be able to track
TVector3D	v The velocity of the object
