Constructor & Destructor Documentation

makVrv::DtTritonWakeUpdater::DtTritonWakeUpdater	(	DtDe &	de,
		DtUniqueID	id
	)

CTOR.

Parameters

[in]	de	is the display engine.
[in]	id	is a unique identifier for this distributed object.

virtual makVrv::DtTritonWakeUpdater::~DtTritonWakeUpdater ( )

virtual

Virtual DTOR.

Member Function Documentation

virtual void makVrv::DtTritonWakeUpdater::update ( DtTime  tNow )

virtual

The update function called by DtTickableManager during update-ticks.

Parameters

[in]

tNow

is the current time-stamp.

Implements makVrv::DtWakeUpdater.

virtual bool makVrv::DtTritonWakeUpdater::needsUpdate ( DtTime  tNow )

virtual

Check if an update is required.

Parameters

[in]

tNow

is the current time-stamp.

Return values

true	if this object needs to be ticked.
false	otherwise.

Reimplemented from makVrv::DtTickable.

virtual void makVrv::DtTritonWakeUpdater::setPosition ( const DtVector &  pos )

virtual

Manually set the current position.

Parameters

[in]

pos

is the position to set.

Note

Only used when ships kinematics cannot be found, such as when creating a wake as a separate entity.

See Also

getCurrentShipKinematics()

Reimplemented from makVrv::DtWakeUpdater.

virtual void makVrv::DtTritonWakeUpdater::setOrientation ( const DtTaitBryan &  ori )

virtual

Manually set the current orientation.

Parameters

[in]

ori

is the orientation to set.

Note

Only used when ships kinematics cannot be found, such as when creating a wake as a separate entity.

See Also

getCurrentShipKinematics()

Reimplemented from makVrv::DtWakeUpdater.

virtual void makVrv::DtTritonWakeUpdater::setIsAmphibious ( bool  isAmphibious )

virtual

Set whether the wake needs to check to see if its over land.

Reimplemented from makVrv::DtWakeUpdater.

virtual DtTritonWakeModel* makVrv::DtTritonWakeUpdater::wakeModel ( ) const

protectedvirtual

Helper method to return a properly cast version of the wake model supplied.

virtual DtVector makVrv::DtTritonWakeUpdater::calcWakeOriginAndSeaLevel ( DtVector &  currentPos, const DtTaitBryan &  orientation, double  wakeOffset  )

protectedvirtual

Calculate the origin of the wake and put currentPos at sea level. These two operations are combined to avoid an extra geocentic-> geodetic conversion.

Parameters

[in]	currentPos	is the entity's position.
[in]	currentOrientation	is the entity's orientation.
[in]	wakeOffset	is offset of the wake start from the entity. center
[out]	currentPos	is modified to be at sea level

Returns

The position of the center of the circle used to generate a Kelvin wake effect.

virtual bool makVrv::DtTritonWakeUpdater::getCurrentShipKinematics ( double  t, DtVector &  position, DtVector &  velocity, DtTaitBryan &  orientation  ) const

protectedvirtual

Get the ship's current position, velocity, and orientation that this 

wake is attached to

virtual bool makVrv::DtTritonWakeUpdater::isLodedOut ( const DtVector &  currentPos ) const

protectedvirtual

internal function to determine if wake is lod'ed out

virtual void makVrv::DtTritonWakeUpdater::slot_coordinateSystemChanged ( )

protectedvirtual

slot for when the coordinate system changes
