Method Detail

reset

void reset()

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

nearestDistance

double nearestDistance(BVNode node)

Computes the nearest distance to the bounding node

Parameters:

node - node to check distance to

Returns:

distance to node

nearestDistance

double nearestDistance(Boundable e)

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

Parameters:

e - element for which distance is to be computed

Returns:

nearest distance to e

nearestObject

Boundable nearestObject()

Returns the last computed nearest Boundable object

Returns:

last computed nearest object

nearestDistance

double nearestDistance()

Returns the last computed nearest distance

Returns:

last computed nearest distance

nearestPoint

Point3d nearestPoint()

Returns the last computed nearest point, in local coordinates.

Returns:

last computed nearest point
