Abstract: There is provided an information processing apparatus, an information processing method, and a program for enabling clients to perform processing efficiently. From 3D data representing a three-dimensional structure, identification information regarding an individual stream of geometry information indicating a geometry of the three-dimensional structure and identification information regarding an individual stream of attribute information indicating an attribute of the three-dimensional structure are generated. A file is generated that includes generated multiple pieces of the identification information. The file is generated in a sample structure specifying boundaries of the geometry information and the attribute information. The present technology may be applied, for example, to a data generation apparatus for generating data for point cloud distribution and to a data reproduction apparatus for point cloud reproduction.

Abstract: There is provided an information processing apparatus and an information processing method that can enhance the image quality while, at the same time, reducing increase in client's throughput. Image data of a plurality of projection directions is generated by projecting 3D data in a plurality of projection directions and converting the 3D data into two-dimensional data, and projection direction information indicating the projection direction of each piece of the image data is generated as projection metadata. Further, the projection direction information includes additional projection direction identification information that indicates that the image data has been generated by projection in additional projection directions. The present technology is applicable, for example, to a data generation apparatus that generates data for delivering a point cloud.
