Assign from a chord intersection record.

void DtGroundInteractionPt::init	(	const DtVector &	localPosition,

Not virtual, because called from constructor.

virtual bool DtGroundInteractionPt::isOnGround ( )

virtual

Returns true if myAltitude <= 0.0.

virtual DtFloat64 DtGroundInteractionPt::calculatePosition ( )

virtual

Calculates position in world coordinates, and returns altitude above or below ground.

Above ground is defined as positive altitude. Also sets the ground position.

virtual void DtGroundInteractionPt::calculatePositionWithoutGround ( )

virtual

Just calculate the position value using the parent's position.

virtual const DtVector& DtGroundInteractionPt::localPosition ( ) const

virtual

virtual void DtGroundInteractionPt::setLocalPosition ( const DtVector &  position )

virtual

virtual void DtGroundInteractionPt::setPosition ( const DtVector &  position )

virtual

virtual DtVector DtGroundInteractionPt::calculateOnGroundPlanePosition ( ) const

virtual

If the ground interaction point is used to actually place an object on the ground by offsetting the object's position relative to the ground by the interaction point offset amounts, this is the position on the plane in which the (offset) object will lie, directly above the ground interaction point.

This can only be used if the groundPosition() has already been determined by calling calculatePosition() (or set directly via mutator) and the parentOrientation has been provided.

virtual const DtVector& DtGroundInteractionPt::position ( ) const

virtual

These simply return the corresponding member variable.

calculatePosition() must be called for them to be up-to-date.
