INFORMATION PROCESSING APPARATUS, METHOD OF CONTROLLING THE SAME, PROGRAM, AND STORAGE MEDIUM

摘要

An information processing apparatus acquires viewpoint information indicating a viewpoint for which rendering of a 3D scene is performed and generates, by a predetermined calculation, a viewpoint independent map for an object included in a rendering scope based on the acquired viewpoint information. And then the apparatus stores each pixel of the generated viewpoint independent map in association with a distance between an object corresponding to the pixel and the viewpoint indicated by the acquired viewpoint information. The apparatus does not perform the predetermined calculation in a case where a pixel of the viewpoint independent map for the object included in the rendering scope corresponding to the distance from the viewpoint indicated by the acquired viewpoint information is already stored.
