Detailed Description

Provides a simple actuator model for surface vessels.

Provides a simple, kinematics-based model for sub surface vessels; derived from surface entity simple actuator, but includes depth inputs.

End User Description: A simple subsurface ship actuator that provides for vessels to move according to acceleration, speed and turn commands. In effect, low level actions such as setting the engine commands (forward/back, amount) and rudder commands (degrees) are abstracted away. The inputs are simply desired acceleration, desired turn radius, and final speed/heading. This makes this actuator something of a low-level controller. The DtSubSurfaceEntitySimpleActuator converts acceleration and turn radius inputs into orientation (heading), acceleration, velocity, and position.
In addition, this actuator has depth rate and clamp depth inputs

Uses Descriptor Type: DtSubSurfaceEntitySimpleActuatorDescriptor

Removes myProcessState from the process state repository manager. Deletes all ports and port groups.

Member Function Documentation

virtual bool DtSubSurfaceEntitySimpleActuator::init ( )
virtual

Calls the base init, then sets initial values for PSR depth rate and clamp depth.

Also sets mySurfacedAltitude.

Reimplemented from DtSurfaceEntitySimpleActuator.

virtual const char* DtSubSurfaceEntitySimpleActuator::type ( ) const
virtual

Returns a string identifies the class type of component.

Type values are defined in compTypes.h. DtSimComponent creation functions are registered with the DtSimComponentFactory using the type values as the key. Warning: this function should always return the same pointer and it should be valid forever. This means the data should be static.

Returns
DtSubSurfaceEntitySimpleActuatorType

Reimplemented from DtSurfaceEntitySimpleActuator.

static DtSimComponent* DtSubSurfaceEntitySimpleActuator::creator ( const DtString name,
DtVrfObject owner,
DtSimManager simManager,
DtComponentDescriptor desc = 0,
DtReaderWriterRegistry parentRegistry = 0 
)
static

Parameters
nameReader writer name of this component.
ownerThe DtVrfObject that owns this component
simManagerThe simulation manager (provides access to terrain, message interface, simulation clock).
descThe component descriptor used to initialize this component.
parentRegistryPointer to the parent reader writer registry (the containing object that reads/writes this object).
Returns
New instance of this class.
virtual bool DtSubSurfaceEntitySimpleActuator::createPorts ( )
protectedvirtual

Creates the depthRate and clampDepth ports, and calls the parent createPorts() to create the rest.

Reimplemented from DtSurfaceEntitySimpleActuator.

virtual void DtSubSurfaceEntitySimpleActuator::tick ( )
protectedvirtual

Ticks the parent, then sets depth ports/data received.

Reimplemented from DtSurfaceEntitySimpleActuator.

virtual double DtSubSurfaceEntitySimpleActuator::updateVerticalSpeed ( const double  dt)
protectedvirtual

Sets the vertical speed according to the input port.

Negates it so that positive is UP.

Reimplemented from DtSurfaceEntitySimpleActuator.

virtual void DtSubSurfaceEntitySimpleActuator::adjustAttitude ( const double  newSpeed,
const DtVector position,
const double  yawRate,
double roll,
double pitch,
double altitude 
)
protectedvirtual

Adjusts the attitude of the entity for improved appearance.

For subsurface: the roll is 0. The pitch is determined by the depthRate and speed: it is set to match depthRate/speed. However, if speed is very low pitch is left to 0. Pitch is constrained to a maximum. AltitudeAdj is left at 0. This value is not used for in setting a subsurface vessel altitude.

Reimplemented from DtSurfaceEntitySimpleActuator.

virtual double DtSubSurfaceEntitySimpleActuator::altitudeFromDepth ( double  depth,
double  surfaceAltitude 
)
protectedvirtual

This function computes the altitude of the entity's origin from a depth.

Depth is the distance of the bottom of the bounding box below the surface of the water (in meters; positive number means deeper, i.e. the negative of altitude). The function uses the latticeOffset of the bounding volume, which is the vector from the entity's origin to the center of the bounding box...but in topographic coordinates, so the Z component is positive-down. So the formula is altitude = -depth + bb.halfHeight + bb.latticeOffset[2] + surfaceAlt. Example: origin at center of bb, surfaceAltitude = 0: depth of 0 => altitude is 1/2 bb height, putting the bottom of the bb at the surface altitude. Example: origin at bottom of bb (latticeOffset[2]= -halfHeight): depth of 20 => altitude= -20 + halfHeight - halfHeight = -20, putting the bottom of the bb at -20.

Member Data Documentation

DtAnalogInputPort* DtSubSurfaceEntitySimpleActuator::myDepthRatePort
protected

Desired depth change rate, in m/s.

Note that increasing depth is decreasing altitude.

DtAnalogInputPort* DtSubSurfaceEntitySimpleActuator::myClampDepthPort
protected

Final desired depth that entity is trying to change to.

This prevents overshoot if dT is unexpectedly large one tick.

double DtSubSurfaceEntitySimpleActuator::myDepth
protected

Computed and cached within a tick, to avoid recomputation.

double DtSubSurfaceEntitySimpleActuator::myAltitudeRate
protected

The negative of depthRate on the input port, or 0 if the port isn't active.
