Information processing apparatus, generation method, and storage medium

摘要

An information processing apparatus analyzes an importance distribution in a render target range for which a three-dimensional scene is to be rendered in a perspective for generating a map for use in rendering the three-dimensional scene. The apparatus acquires eigenvectors of the importance distribution by performing principal component analysis on the distribution. In a case where the eigenvectors of the distribution satisfies a predetermined condition, the apparatus rotates the importance distribution such that a direction defined by the eigenvector is to be a predetermined direction, and determines the number of pixels assigned to each partial region based on the rotated distribution.

1. An information processing apparatus that generates a map for use in rendering a three-dimensional scene, the information processing apparatus comprising:
a processor; and a memory including instructions that, when executed by the processor, cause the processor to perform operations including:
analyzing an importance distribution in a render target range for which the three-dimensional scene is to be rendered in a perspective for generating the map;performing principal component analysis on the importance distribution to acquire eigenvectors of the importance distribution;determining whether the eigenvectors of the importance distribution satisfy a predetermined condition, and when the predetermined condition is satisfied, rotating the importance distribution such that a direction defined by an eigenvector is to be a predetermined direction;assigning a number of pixels to each partial region in the render target range based on the rotated importance distribution;generating the map based on the number of pixels assigned to each partial region; and rendering the three-dimensional scene using the map.
