HYBRID TREE CODING FOR INTER AND INTRA PREDICTION FOR GEOMETRIC CODING

An apparatus for decoding a bitstream comprising point cloud data is configured to: determine an octree defining an octree-based partition of a space containing a point cloud, where leaf nodes of the octree contain one or more points of the point cloud; and directly decoding the location of each of the one or more points in the leaf node, where, for directly decoding the location of each of the one or more points in the leaf node, the one or more processors are further configured to: generate a prediction of the one or more points; and determining one or more points based on the prediction. 用于解码包括点云数据的比特流的设备被配置为：确定定义包含点云的空间的基于八叉树的划分的八叉树，其中，八叉树的叶节点包含点云的一个或多个点；以及直接解码叶节点中的一个或多个点中的每个点的位置，其中，为了直接解码叶节点中的一个或多个点中的每个点的位置，一个或多个处理器还被配置为：生成一个或多个点的预测；以及基于预测来确定一个或多个点。
