Input Parameters

• box - The grid hash object

• numPoints - The number of input points

• points - The input point coordinates

Output Parameters

• dboxes - An array of numPoints x dim integers expressing the enclosing box as (i_0, i_1, …, i_dim)

• boxes - An array of numPoints integers expressing the enclosing box as single number, or NULL
