Claim 16:
17. The method of claim 1, wherein constructing the octree further includes:
updating a parameter K indicating a maximal number of implicit QT and BT partitions before octree (OT) partitions, and a parameter M indicating a minimal size of implicit QT and BT partitions that prevents implicit QT and BT partitions of a node when all dimensions of the node are smaller than or equal to the minimal size according to:
if K is greater than a difference between a maximum root node log 2 dimension and a minimum root node log 2 dimension of the slice, K is changed to a difference between the maximum root node log 2 dimension and the minimum root node log 2 dimension of the slice;
if M is greater than the minimum root node log 2 dimension of the slice, M is changed to the minimum root node log 2 dimension of the slice;
if the maximum root node log 2 dimension and the minimum root node log 2 dimension of the slice are equal, M is changed to 0; and
if a trisoup mode is enabled, K is changed to the difference between the maximum root node log 2 dimension and the minimum root node log 2 dimension of the slice, and M is changed to the minimum root node log 2 dimension of the slice.
