Detailed Description

Class Invariant: The DtGroundInteractionPt class must always have a valid DtAttachedTerrain or DtSimManager pointer.

Constructor & Destructor Documentation

DtGroundInteractionPt::DtGroundInteractionPt

(

)

DtGroundInteractionPt::DtGroundInteractionPt	(	const DtVector &	localPosition,
		DtAttachedTerrain &	refFrame
	)

virtual DtGroundInteractionPt::~DtGroundInteractionPt ( )

virtual

DtGroundInteractionPt::DtGroundInteractionPt

(

const DtGroundInteractionPt &

original

)

Copy constructor.

Member Function Documentation

DtGroundInteractionPt& DtGroundInteractionPt::operator=

(

const DtGroundInteractionPt &

original

)

Assignment operator.

DtGroundInteractionPt& DtGroundInteractionPt::operator=

(

const DtChordIntersectionRecord &

intersectionRecord

)

Assign from a chord intersection record.

void DtGroundInteractionPt::init	(	const DtVector &	localPosition,
		DtAttachedTerrain &	terrainAttachedTo
	)

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 DtAttachedTerrain* DtGroundInteractionPt::terrainAttachedTo ( )

virtual

virtual const DtAttachedTerrain* DtGroundInteractionPt::terrainAttachedTo ( ) const

virtual

virtual void DtGroundInteractionPt::setTerrainAttachedTo ( DtAttachedTerrain *  newTerrainAttachedTo )

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.

virtual DtFloat64 DtGroundInteractionPt::altitude ( ) const

virtual

virtual void DtGroundInteractionPt::setAltitude ( DtFloat64  alt )

virtual

virtual const DtVector& DtGroundInteractionPt::groundPosition ( ) const

virtual void DtGroundInteractionPt::setSoilType ( DtRoughnessSoilType  type )

virtual

virtual const DtSurface& DtGroundInteractionPt::surface ( ) const
