Claim 15:
16. The method of claim 1, wherein the constructing the octree includes:
performing a geometry octree occupancy process, where for a bin having an index of binIdx in an occupancy code, a variable binIsInferred is set according to the following:, if either of the following conditions are true, binIsInferred is set equal to 1:
(1) a variable NeighbourPattern is equal to 0 and a number of previously encoded 1-valued bins is less than or equal to (binIdx+minOccupied−maxOccupied), or
(2) the variable NeighbourPattern is not equal to 0, binIdx is equal to maxOccupied −1 and values of all previously encoded bins are zero,
where minOccupied=2, and maxOccupied=8 if an octree (OT) partition is applied, maxOccupied=4 if the QT partition is applied, maxOccupied=2 if the BT partition is applied, and
otherwise, if neither of the above conditions are true, binIsInferred is set equal to 0.
