Return the temporal parent cell at the given resolution. The no-argument form drops to the next-coarser resolution.

th3CellToParent(th3index,integer) → th3index

th3CellToParent(th3index) → th3index

SELECT th3GetResolution(
  th3CellToParent(th3index '8a2a1072b59ffff@2001-01-01', 5));
-- 5@2001-01-01

Return the temporal center-child cell at the given resolution. The no-argument form drops to the next-finer resolution.

th3CellToCenterChild(th3index,integer) → th3index

th3CellToCenterChild(th3index) → th3index

Return the ordinal position (0-based) of each cell among the children of its parent at the given resolution

th3CellToChildPos(th3index,integer) → tbigint

Return the temporal child cell at a given ordinal position of the given parent, at the given child resolution. The two temporal operands are synchronised over their shared time axis.

th3ChildPosToCell(tbigint,th3index,integer) → th3index
