Constructor Details

UniformGrid4dImpl

public UniformGrid4dImpl(double cellSize)

Constructor.

Parameters:

cellSize - Cell size. Must be bigger that one.

UniformGrid4dImpl

public UniformGrid4dImpl(double cellSize,
 Collection<V> objects,
 Function<? super V,javax.vecmath.Tuple4d> mapFunc)

Constructor. As the mapping function, use (Point4d p) -> p, for instance.

Parameters:
