Package cds.healpix

Class HealpixNestedUltraCompactMOC


  • public class HealpixNestedUltraCompactMOC
    extends java.lang.Object
    The idea is to use an implicit datastructure, encoding the natural tree traversal on bits with: - 0 bit: cell not in the MOC, go to the next sibling cell or go up if all siblings already explored - 1 bit: cell contains information, go deeper - 0000 bits: parent cell is in the MOC, no need to go deeper (ony for cells of depth < depthMax) (DISCLAIMER: for a more recent and slightly more compact version, see the CDS HEALPix Rust)
