Claim One:
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.
