public boolean isWithin(double x, double y, double z) Description copied from interface:GeoStandardPath.PathComponent
Check if point is within this endpoint.- Specified by:
isWithin
in interfaceGeoStandardPath.PathComponent
- Specified by:
isWithin
in interfaceMembership
- Parameters:
x
- is the point x.y
- is the point y.z
- is the point z.- Returns:
- true of within.
-
isWithinSection
public boolean isWithinSection(double x, double y, double z) Description copied from interface:GeoStandardPath.PathComponent
Check if point is within this section (within cutoff planes).- Specified by:
isWithinSection
in interfaceGeoStandardPath.PathComponent
-
isWithinSection

getStartingDistance
Description copied from interface:GeoStandardPath.PathComponent
Retrieve the starting distance along the path for this path element.- Specified by:
getStartingDistance
in interfaceGeoStandardPath.PathComponent
- Parameters:
distanceStyle
- is the distance style- Returns:
- the starting path distance in aggregation form
-
distance
Description copied from interface:GeoStandardPath.PathComponent
Compute distance measure starting from beginning of the path and including perpendicular dog-leg to a point within the corridor.- Specified by:
distance
in interfaceGeoStandardPath.PathComponent
- Parameters:
distanceStyle
- is the distance stylex
- is the x coordinate of the point we want to get the distance toy
- is the y coordinate of the point we want to get the distance toz
- is the z coordinate of the point we want to get the distance to- Returns:
- the distance from start of path
-
nearestDistance
public GeoStandardPath.DistancePair nearestDistance(DistanceStyle distanceStyle, double x, double y, double z) Description copied from interface:GeoStandardPath.PathComponent
Get the nearest distance for a point. This is the old "legacy" computation: We find the segment endpoint or path segment with the closest pathCenterDistance(), and keep track of the one where that's at a minimum. We then compute nearestPathDistance() if it's a segment and add that to fullPathDistance() computed along the entire path up to that point.So what we are minimizing is not what we are returning here. That is why this is tricky to modularize; we need to return two values: the best pathCenterDistance, and the corresponding nearestPathDistance + startingDistance.
- Specified by:
nearestDistance
in interfaceGeoStandardPath.PathComponent
- Parameters:
distanceStyle
- is the distance stylex
- is the x coordinate of the point we want to get the distance toy

- the DistancePair containing both distances described above
