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.

Abstract: A laser hazard at the time of non-connection can be prevented with a simple structure. A cylindrical connector exterior, and a block that is incorporated in one end side of the connector exterior and in which a light emitting portion or a light incident portion is mounted toward another end side are included. The light emitting portion or the light incident portion is mounted on the block such that an optical axis direction of the light emitting portion or the light incident portion is inclined with respect to a longitudinal direction of the connector exterior. For example, the connector exterior has a length at which at least a part of light emitted from the light emitting portion can be emitted to an inner side (inner wall) of the connector exterior.

Abstract: The present disclosure relates to an information processing apparatus and an information processing method that enable processing to be performed simply, and a program.
By converting a point cloud representing a three-dimensional structure into two dimensions, a geometry image and a texture image, and three-dimensional information metadata required for constructing the geometry image and the texture image in three dimensions are obtained. Then, one PC sample included in a Point Cloud displayed at a specific time is generated by storing the geometry image, the texture image, and the three-dimensional information metadata in accordance with a playback order required at a time of reproducing and playing back the geometry image and the texture image in three dimensions on the basis of the three-dimensional information metadata. It is possible to apply to a data generation device that generates data for distribution of a Point Cloud.

Abstract: There is provided a generation device, an identification information generation method, a reproduction device, and an image reproduction method capable of identifying a packing scheme. Stereo packing identification information for identifying a scheme of packing is generated with regard to a plurality of region images of a celestial sphere image packed in a packed frame. In a case in which packing is performed by one of a plurality of packing schemes, stereo packing identification information indicating a packing method can be generated, a projected frame can be generated easily on the basis of the identification information, and the projected frame can be rendered. The present technology can be applied to a case in which a celestial sphere stereoscopic image is transmitted to be reproduced on a reception side.
