1. A method of coding point cloud data, the method comprising:
determining that a first node of an octree of point cloud data is not inter predictable;
in response to determining that the first node is not inter predictable, determining an inferred direct coding mode (IDCM) mode for the node;
coding occupancy data of the first node using the determined IDCM mode;
determining that a second node of the octree is inter predictable and that angular mode is disabled for the second node; and
in response to determining that the second node is inter predictable and that angular mode is disabled for the second node, coding occupancy data of the second node using inter prediction.
