[−][src]Function moore_hilbert_sys::hilbert_box_pt

pub unsafe extern "C" fn hilbert_box_pt(
    nDims: c_uint, 
    nBytes: c_uint, 
    nBits: c_uint, 
    findMin: c_int, 
    coord1: *mut c_void, 
    coord2: *mut c_void
) -> c_uint

Determine the first or last point of a box to lie on a Hilbert curve

Arguments

  • nDims - Number of coordinates.
  • nBytes - Number of bytes/coordinate.
  • nBits - Number of bits/coordinate.
  • findMin - Is it the least vertex sought?
  • coord1 - Array of nDims nBytes-byte coordinates - one corner of box
  • coord2 - Array of nDims nBytes-byte coordinates - opposite corner

Returns

c1 and c2 are modified to refer to the least point

Assumptions

nBits <= (sizeof BitmaskT) * (bits_per_byte)
