Method Detail

reset

public void reset()

Description copied from interface: BVFeatureQuery.ObjectDistanceCalculator

Reset any internal `nearest' cache so calculator can be re-used

Specified by:

reset in interface BVFeatureQuery.ObjectDistanceCalculator

setPoint

public void setPoint(Point3d pnt,
                     RigidTransform3d XBvhToWorld)

setPoint

public void setPoint(Point3d pnt)

nearestDistance

public double nearestDistance(BVNode node)

Description copied from interface: BVFeatureQuery.ObjectDistanceCalculator

Computes the nearest distance to the bounding node

Specified by:

nearestDistance in interface BVFeatureQuery.ObjectDistanceCalculator

Parameters:

node - node to check distance to

Returns:

distance to node

nearestDistance

public double nearestDistance(Boundable e)

Description copied from interface: BVFeatureQuery.ObjectDistanceCalculator

Computes the nearest distance to an element within the node. This should store the object and distance for later use by BVFeatureQuery.ObjectDistanceCalculator.nearestObject() and BVFeatureQuery.ObjectDistanceCalculator.nearestDistance()

Specified by:

nearestDistance in interface BVFeatureQuery.ObjectDistanceCalculator

Parameters:

e - element for which distance is to be computed

Returns:

nearest distance to e

nearestPoint

public Point3d nearestPoint()

Description copied from interface: BVFeatureQuery.ObjectDistanceCalculator

Returns the last computed nearest point, in local coordinates.

Specified by:

nearestPoint in interface BVFeatureQuery.ObjectDistanceCalculator

Returns:

last computed nearest point

nearestObject

public FemElement3dBase nearestObject()

Description copied from interface: BVFeatureQuery.ObjectDistanceCalculator

Returns the last computed nearest Boundable object

Specified by:

nearestObject in interface BVFeatureQuery.ObjectDistanceCalculator

Returns:

last computed nearest object

nearestDistance

public double nearestDistance()

Description copied from interface: BVFeatureQuery.ObjectDistanceCalculator

Returns the last computed nearest distance

Specified by:

nearestDistance in interface BVFeatureQuery.ObjectDistanceCalculator

Returns:

last computed nearest distance
