Detailed Description

An object containing functions to find obstructions in road segments in a road path; part of a DtRoadMovementController.

This class finds obstructions along rail segment lists, and provides details of these obstructions.

Member Function Documentation

virtual void DtRoadObstructionFinder::init ( const DtRwObjectTypeList &  passableObjectTypes )

virtual

virtual bool DtRoadObstructionFinder::findFirstObstructionInLane ( const DtRoadSegment *  startSegment, const int  roadLaneNum, const double  positionAlongLane, double  lookDistance, DtRailObstructionPtr &  result, std::vector< std::vector< DtVector > > &  debugBoxes, bool  debug = false  ) const

virtual

Looks for obstructions along the given road, starting at the provided lane and position in lane for the specified distance along the lane and connecting lanes in downstream segments.

Fills the result rail obstruction object ptr with obstruction information for the first obstacle object found in the lane.

Parameters

result

This obstruction object is created if there is an obstruction found. If the function returns false, this pointer is not valid.

Returns

True if an obstacle object was found; false otherwise.

virtual bool DtRoadObstructionFinder::findFirstObstructionUpstreamInLane ( const DtRoadSegment *  startSegment, const int  roadLaneNum, const double  positionAlongLane, double  lookDistance, DtRailObstructionPtr &  result, std::vector< std::vector< DtVector > > &  debugBoxes, bool  debug = false  ) const

virtual

Looks for obstructions along the given road, starting at the provided local location for the specified distance along the rail.

Fills the result rail obstruction object ptr with obstruction information for the first obstacle object found in the lane.

Parameters

result

This obstruction object is created if there is an obstruction found. If the function returns false, this pointer is not valid. Note that the myRailObstructionInfo->startBlockDistance in this object is the distance upstream to the front of the obstacle, vs. the distance downstream to the back of the vehicle as in findFirstObstructionInLane.

Returns

True if an obstacle object was found; false otherwise.

virtual bool DtRoadObstructionFinder::findNearestObstructionInSegment ( const DtRoadSegment *  segment, const int  roadLaneNum, const double  distFromSegStart, const double  testDistance, DtRailObstructionPtr &  obstruction, std::vector< std::vector< DtVector > > &  debugBoxes, bool  debug = false  ) const

protectedvirtual

Finds all obstructions along the specified segment, in the given lane, starting at distFromSegStart and running for the specified testDistance.

Parameters

obstruction

This obstruction object is created if there is an obstruction found. If the function returns false, this pointer is not valid.

Returns

True if an obstacle object was found; false otherwise.

virtual bool DtRoadObstructionFinder::findNearestObstructionUpstreamInSegment ( const DtRoadSegment *  segment, double  testAltitude, const int  roadLaneNum, const double  distFromSegStart, const double  testDistance, DtRailObstructionPtr &  obstruction, std::vector< std::vector< DtVector > > &  debugBoxes, bool  debug = false  ) const

protectedvirtual

Finds all obstructions along the specified segment, starting at distFromSegStart, and running for the specified testDistance.

Parameters

obstruction

This obstruction object is created if there is an obstruction found. If the function returns false, this pointer is not valid.

Returns

True if an obstacle object was found; false otherwise.

void DtRoadObstructionFinder::getBoxPointsFromVolume ( Dt3dBoundingVolume &  volume, DtVector &  refPoint, DtDcm &  orientation, std::vector< std::vector< DtVector > > &  outputList  ) const

protected

Generates the (5) world points defining rectangle that is a horizontal slice through the given volume at the midpoint of the volume.

Used to generate a visualization of the volume.
