Constructor Details

UniformGrid3dImpl

public UniformGrid3dImpl(double cellSize)

Constructor.

Parameters:

cellSize - Cell size. Must be bigger that one.

UniformGrid3dImpl

public UniformGrid3dImpl(double cellSize,
 Collection<V> objects,
 Function<? super V,javax.vecmath.Tuple3d> mapFunc)

Constructor. As the mapping function, use (MeshPoint mp) -> mp.getPosition() or (Point3d p) -> p, for instance.

Parameters:

cellSize - Cell size. Must be bigger that one.

objects - Objects to be stored

mapFunc - A function that computes a 3D space location from an object
