sphere_id[i] indicates the identifier of the i-th sphere in the Cartesian coordinates.
sphere_center_offset_x[i] indicates the x offset of the i-th sphere center in the Cartesian coordinates.
sphere_center_offset_y[i] indicates the y offset of the i-th sphere center in the Cartesian coordinates.
sphere_center_offset_z[i] indicates the z offset of the i-th sphere center in the Cartesian coordinates.
sphere_radius[i] indicates the radius of the i-th sphere in the Cartesian coordinates.
According to embodiments, SphereRegionStruct(i) may contain information about other shapes as well as sphere.
