Abstract: There is provided an information processing apparatus and an information processing method that enable use of a thumbnail for 3D object still image content. A 3D object is used as original data, and role information that is information indicating that thumbnail data generated from the original data is a thumbnail based on the original data is generated. Then, the role information and encoded data obtained by encoding one frame of the 3D object by a predetermined encoding method are stored in a file having a predetermined file structure. The present technology can be applied to, for example, a data generation apparatus that generates a file that stores encoded data of Point Cloud without time information and its thumbnail.
