Claim 14:
15. A non-transitory computer readable medium having stored thereon a computer program for decoding point cloud data, the computer program configured to cause one or more computer processors to:
receive data corresponding to a point cloud;
reduce a number of contexts associated with the received data based on reducing a size of an context array corresponding to syntax elements for predictive tree-based coding of the point cloud, wherein the context array is a three-dimensional array that indicates a total number of contexts required to encode the syntax elements associated with the received data, wherein the reducing comprises reducing a size of at least one dimension of the context array from a first value to a second value less than the first value; and
decode the received data corresponding to the point cloud based on the reduced number of contexts.
