Constructor Details

MeshDistanceVisitorImpl

protected MeshDistanceVisitorImpl(boolean relativeDistance,
 boolean parallel)

Constructor.

Parameters:

relativeDistance - If true, then the visitor calculates the relative distances with respect to the normal vectors of source facets (normal vectors have to present), i.e., we can get negative distances.

parallel - If true, then the algorithm runs concurrently utilizing all CPU cores

Throws:

IllegalArgumentException - if some parameter is wrong

Method Details

getDistancesOfVisitedFacets

public MeshDistances getDistancesOfVisitedFacets()

Description copied from interface: MeshDistanceVisitor

Returns the distance of inspected mesh facets to the source mesh facets.

If non or multiple closest points were found or if the point was auto-cropped, then the distance is set to Double.POSITIVE_INFINITY and the nearest neighbor is set to null.

Specified by:

getDistancesOfVisitedFacets in interface MeshDistanceVisitor

Returns:

the distance of inspected mesh facets to the source mesh facets.

relativeDistance

public boolean relativeDistance()

Description copied from interface: MeshDistanceVisitor

Returns true if the distance was computed as relative (with possibly negative values).

Specified by:

relativeDistance in interface MeshDistanceVisitor

Returns:

true if the distance is computed as relative, false otherwise.

inParallel

public boolean inParallel()

Description copied from interface: MeshDistanceVisitor

Returns true if the distance computation is parallel.

Specified by:

inParallel in interface MeshDistanceVisitor

Returns:

true if the distance computation is parallel.

dispose

public void dispose()

Description copied from interface: MeshVisitor

Dispose all disposable resources this visitor was using. Distances can still be retrieved after calling this method. Subclasses should override this method if they need to dispose something.

Specified by:

dispose in interface MeshVisitor
