摘要： A three-dimensional data encoding method includes: performing a conversion process including a displacement on, out of first point cloud data and second point cloud data having a same time, the second point cloud data, and combining the first point cloud data and the second point cloud data after being subjected to the conversion process, to generate third point cloud data (S6131); and encoding the third point cloud data to generate a bitstream (S6132). The bitstream includes first information and second information, the first information indicating to which of the first point cloud data and the second point cloud each of three-dimensional points included in the third point cloud data belongs, the second information indicating details of the displacement.

摘要： Apparatus and method for lossy displaced mesh compression. For example, one embodiment of an apparatus comprises: displacement mapping circuitry/logic to generate an original displacement-mapped mesh by performing a displacement mapping of a plurality of vertices of a base subdivision mesh; and mesh compression circuitry/logic to compress the original displacement-mapped mesh, the mesh compression circuitry/logic comprising a quantizer to quantize the displacement mapping of the plurality of vertices in view of a base mesh to generate a displacement array.
