OG exemplary drawing
 
1. An information processing apparatus comprising:
one or more memories storing instructions; and
one or more processors executing the instructions:
to obtain volumetric video data consisting of a sequence of frames, each frame including object shape data, and the volumetric video data including metadata that associates each of the objects and the shape data in each frame;
to select a specific object based on the obtained volumetric video data;
to generate a camera path indicating a movement path of a virtual viewpoint from which it is possible to visually recognize the selected specific object favorably, based on at least one piece of information of information regarding a three-dimensional position and an attribute of the object included in the metadata relating to the selected specific object and a circumscribed rectangle of a three-dimensional shape indicated by the shape data;
to set one or a plurality of objects at least including the selected specific object as a drawing target based on the metadata added to the volumetric video data; and
to perform drawing using the shape data associated with the one or the plurality of objects set as the drawing target, based on the generated camera path and the metadata added to the volumetric video data.
