makVrv::DtRotorWashProcess Class Reference

DtRotorWashProcess maintains a model of the rotary wing entity's rotor wash, such as speed; dead reckoned position, intensity, and lag, e.g. using information from the entity's parameters and data from it's.

See Also

DtSceneObject. It then updates the currently active rotor wash visual model using that rotor wash's

DtRotorWashDistributor.

Member Function Documentation

virtual void makVrv::DtRotorWashProcess::setHelicopterId ( DtUniqueID  helicopterID )

virtual

Initializes the scene object for the object id being processed.

virtual bool makVrv::DtRotorWashProcess::update ( DtTime  tNow )

virtual

The update function called by DtTickableManager during update-ticks.

Parameters

[in]

tNow

is the current time-stamp.

Note

Derived classes should update the rotorWash at the end of their implementation of this function.

virtual DtVector makVrv::DtRotorWashProcess::currentHeloPosition ( ) const

virtual

Retrieve the current helicopter position from the scene object.

virtual DtTaitBryan makVrv::DtRotorWashProcess::currentHeloOrientation ( ) const

virtual

Retrieve the current helicopter orientation from the scene object.

virtual void makVrv::DtRotorWashProcess::calcRotorWashLagRelOffset ( const DtTime &  tNow, const DtVector &  currentHeliPos, const DtTaitBryan &  currentHeliOri, DtVector &  outRelativeOffset, double &  lagHeliAngleDistToGround  )

virtual

Lag rotorwash based on height and velocity outOffsetPos = the position of the lagged rotorwash based on current helicopter position in coordinates relative to the the helicopter and using DIS (forward, right, down) style lagHeliAngleDistToGround is the distance from the helicopter to the rotorwash at the lag posion.

virtual void makVrv::DtRotorWashProcess::setRotorWashState ( const DtRotorWashState *  rwState )

virtual

Set the parameters for the current active rotorwash.

virtual DtVector makVrv::DtRotorWashProcess::currentHeliPos ( ) const

virtual

Accessors for the DtRotorWashProcess Current helicopter position.

virtual

Current helicopter orientation.

virtual DtVector makVrv::DtRotorWashProcess::offsetPos ( ) const

virtual

Position of rotorwash relative to helicopter.

virtual float makVrv::DtRotorWashProcess::intensity ( ) const

virtual

0 - no rotorwash to 1 - full rotorwash

virtual float makVrv::DtRotorWashProcess::rotorWashSpeed ( ) const

virtual

Rotorwash speed in meters per second (default 100 m/s)

virtual DtVector makVrv::DtRotorWashProcess::rotorWashPos ( ) const

virtual

virtual void makVrv::DtRotorWashProcess::addNewRotorWashPoint ( DtTime  tNow, const DtVector &  newPoint  )

virtual

add a new rotor was point and update offset and intensity

DtRotorWashProcess& makVrv::DtRotorWashProcess::operator= ( const DtRotorWashProcess &  other )

private

Assignment Operator Not implemented – Assignment Not Allowed.

protectedvirtual

Convert an offset calculated in world coordinates to a DIS style (forward, right, down) offset relative to the helicopter.

virtual bool makVrv::DtRotorWashProcess::allObservers2D ( ) const

protectedvirtual

Determine if all observers are 2D so we can skip updating (The rotorwash will appear to start again when switching to 3D)

virtual void makVrv::DtRotorWashProcess::slot_coordinateSystemChanged ( )

protectedvirtual

slot for when the coordinate system changes
