Inter prediction coding and decoding for geometry point cloud compression

An example of processing a point cloud includes, in response to determining to predict a current point in the point cloud using predictive geometry coding, selecting a prediction mode for the current point from a set of prediction modes, where the set of prediction modes includes at least an intra prediction mode and an inter prediction mode; and predicting the current point of the point cloud using inter prediction in response to selecting the inter prediction mode for the current point. 处理点云的示例包括：响应于确定使用预测几何体编解码来预测点云中的当前点，从预测模式集合中选择用于当前点的预测模式，其中预测模式集合至少包括帧内预测模式和帧间预测模式；以及响应于针对当前点选择帧间预测模式，使用帧间预测来预测点云的当前点。
