Member Function Documentation

virtual bool DtHumanCollisionAvoidanceController::init ( )
virtual

Initializes the follow controller name, the object ID, and the collisionBV (bounding volume)

Returns
A boolean indicating success or failure.

Reimplemented from DtControllerComponent.

virtual void DtHumanCollisionAvoidanceController::tick ( )
virtual

Calculate new control values based on potential collisions.

If the controller has received potential collision data, then it acts to avoid a collision. If it does not receive collision data, but has on the previous tick, then the controller starts clearing the collision.

See Also
avoidCollision()
clearingCollision()

Reimplemented from DtSimComponent.

virtual double DtHumanCollisionAvoidanceController::distanceSquaredToDestination ( DtVector  offsetVector)
virtual

Calculates the distance squared from the current location (in local coords) to the destination, minus the specified offset vector.

Returns
a double set to the distance squared.
virtual void DtHumanCollisionAvoidanceController::avoidCollision ( const DtCollision potentialCollision)
virtual

Activates all control ports/groups and provides the necessary speed, direction, and heading values.

Parameters
potentialCollisionA collision object to avoid.
See Also
avoidMovingObstruction()
avoidNonMovingObstruction()
virtual const char* DtHumanCollisionAvoidanceController::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
DtHumanCollisionAvoidanceControllerType

Implements DtTaskControllerComponent.

static DtSimComponent* DtHumanCollisionAvoidanceController::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.
const DtHumanCollisionAvoidanceController& DtHumanCollisionAvoidanceController::operator= ( const DtHumanCollisionAvoidanceController orig)
protected

assignment operator

virtual bool DtHumanCollisionAvoidanceController::shouldRun ( )
protectedvirtual

whether or not the controller should run this tick, and returns true if it should.

virtual void DtHumanCollisionAvoidanceController::clearCollisionStateData ( )
protectedvirtual

This just cleans up some state variables when it's determined that an entity is no longer potentially colliding.

virtual void DtHumanCollisionAvoidanceController::clearingCollision ( )
protectedvirtual

Moves the vehicle in a straight line for the defined clearingDistance after it is no longer at risk of colliding with the obstruction.

This is done to keep the vehicle from turning back to the goal too soon, which would cause a jitter as the vehicle went in and out of the collision state.

virtual bool DtHumanCollisionAvoidanceController::isInsideObstruction ( const DtCollision potentialCollision,
double clearingDistance 
)
protectedvirtual

Determine if the entity is inside the potential obstruction.

Returns the necessary clearing distance if we are inside the obstruction.

virtual void DtHumanCollisionAvoidanceController::registerTaskMsgCallbacks ( )
protectedvirtual

Override for interest in task complete messages, we care about stopMoving tasks.

Reimplemented from DtTaskControllerComponent.

static void DtHumanCollisionAvoidanceController::taskCompleteReportCallback ( DtSimMessage msg,
void *  usr 
)
staticprotected

Monitor taskReportComplete callback to see when entity stops moving during an embarkation task so we can stop collision avoiding.

virtual void DtHumanCollisionAvoidanceController::processTaskComplete ( DtSimMessage msg)
protectedvirtual
bool DtHumanCollisionAvoidanceController::isAppreciablyMoving ( DtVector  velocity,
double  velocityTolerance 
) const
protected

If the magnitude of any component of the velocity is greater than the velocity tolerance, then the entity is considered appreciably moving.

Returns
A boolean signifying whether or not the entity is appreciably moving.
bool DtHumanCollisionAvoidanceController::setDefaultPortValuesForAvoidance ( )
protected

Sets the ports to appropriate default values.

  • Throttle is set to the approximate throttle for the ordered speed.
  • Break is set to either 0 or .5 depending on dif. between current and ordered speed
  • Steering is set to 0.
  • ParkingBrake is set to false
    Returns
    A boolean signifying success or failure.
bool DtHumanCollisionAvoidanceController::determineObstructionMovementDirection ( DtDcm  obstructionLocalOrientationMatrix,
const DtVector obstructionVelocity,
int obstructionDirectionSign 
) const
protected

Determines if the obstruction is moving forward or in reverse.

Parameters
obstructionDirectionSignA reference to an integer representing the direction of movement: 1 for forward, -1 for reverse.
Returns
a boolean signifying success or failure in the calculation.
void DtHumanCollisionAvoidanceController::avoidMovingObstruction ( const DtCollision potentialCollision)
protected

Calculates and sets control values for avoiding a moving obstruction based on obstruction's relative movement (head-on, in front of, etc.) If the obstruction is moving in roughly the same direction, and the entity is in front, it does nothing.

If it is behind, and following the entity, then it lets the follow entity controller take over. If not following the entity, then it slows down to avoid a collision.

If the obstruction is coming head on, then the entity attempts to turn out of the way as if the obstruction was a non-moving entity.

Note
Assumes that the obstruction is an entity, since it is moving. If the potential collision is not an entity, this function will have to be
void DtHumanCollisionAvoidanceController::avoidNonMovingObstruction ( const DtCollision potentialCollision)
protected

Calculates control values for avoiding a non-moving obstruction.

If the entity is not following the obstruction, and the entity can turn, it turns to the opposite direction of the obstruction's location to the entity. (i.e. if the obstruction is on the right, the entity turns to the left.) Otherwise, the entity stops, since either the leader has stopped or it is unable to turn.

virtual void DtHumanCollisionAvoidanceController::calculateAvoidanceByVertices ( const DtVector vertex1,
const DtVector vertex2,
double  entityBoundingVolumeRadius,
DtVector localVectorToDestination,
DtVector localVectorToObstruciton 
)
protectedvirtual

Calculates control values for avoiding using the vertices that define the obstruction.

This is used with objects that have at least 2 vertices

virtual void DtHumanCollisionAvoidanceController::calculateAvoidanceUsingBoundingVolume ( const DtCollision potentialCollision,
double  entityBoundingVolumeRadius,
DtVector localVectorToDestination,
DtVector localVectorToObstruciton 
)
protectedvirtual

Calculates very rough control values for avoiding using the bounding volume.

void DtHumanCollisionAvoidanceController::startClearingCollision ( double  clearingDistance)
protected

Sets state as appropriate for clearing a collision and then starts clearing the collision.

Parameters
clearingDistanceThe distance the entity will move before it considers itself of having fully avoided the collision. This is to prevent entities from immediately turning back into the path of the potential collision once initially avoided it.
See Also
clearingCollision()
bool DtHumanCollisionAvoidanceController::calculateMyEntityCollisionBV ( )
protected

Calculates a bounding volume representing the potential collision volume occupied by the entity.

The entities oriented bounding volume is extended in the direction of travel. It represents a prediction of the entity's future movement for some period of time.

Returns
A boolean signifying success or failure. If the function fails, the bounding volume is not defined to be valid.
Note
Almost exact same function as in the DtObstructionSensor class.
This function assumes simplified movement, and only works for movement "forward/backward" in body coordinates (x direction). For more complicated collision bounding volumes, this function must be overridden.
bool DtHumanCollisionAvoidanceController::createPortGroups ( )
protectedvirtual

Called by init.

Derived classes should override this method to create all their input/output port groups.

Reimplemented from DtSimComponent.

bool DtHumanCollisionAvoidanceController::createPorts ( )
protectedvirtual

Called by init.

Derived classes should override this method to create all their input/output ports and port groups.

Reimplemented from DtSimComponent.

virtual bool DtHumanCollisionAvoidanceController::createPSR ( )
protectedvirtual

Creates myProcessState data member, and adds it to our process state repository manager.

Passes in the name and type specified in the component descriptor (if they exist) to the DtVrfProcessStateRepository::createRepository factory method. If name and/or type is not specified, uses the appropriate default strings defined in procSRTypes.h.
