Class DefaultMotionState

java.lang.Object
  com.bulletphysics.linearmath.MotionState
      com.bulletphysics.linearmath.DefaultMotionState

public class DefaultMotionState
extends MotionState

DefaultMotionState provides a common implementation to synchronize world transforms with offsets.

Field Summary

Transform	centerOfMassOffset Center of mass offset transform, used to adjust graphics world transform.
Transform	graphicsWorldTrans Current interpolated world transform, used to draw object.
Transform	startWorldTrans Initial world transform.

Constructor Summary

DefaultMotionState()
Creates a new DefaultMotionState with all transforms set to identity.

DefaultMotionState(Transform startTrans)
Creates a new DefaultMotionState with initial world transform and center of mass offset transform set to identity.

DefaultMotionState(Transform startTrans, Transform centerOfMassOffset)
Creates a new DefaultMotionState with initial world transform and center of mass offset transform.

Method Summary

Transform	getWorldTransform(Transform out) Returns world transform.
void	setWorldTransform(Transform centerOfMassWorldTrans) Sets world transform.
