Information processing apparatus, control method, and storage medium for defining tiles with limited numbers of fragments

摘要

An information processing apparatus obtains a number of fragments existing on a straight line defined by each pixel of a rectangular image into which a 3D scene is to be rendered for a predetermined viewpoint and a viewpoint, and divides a two-dimensional region in a screen coordinate system corresponding to the rectangular image into a plurality of regions which are processing units for which a predetermined calculation is performed. The apparatus divides the two-dimensional region into different regions by one or more straight line such that a difference in summations of the numbers of fragments included in the regions after the division becomes a minimum.

主权项

1. An information processing apparatus that generates a rectangular image into which a 3D scene is rendered for a predetermined viewpoint, 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:
obtaining a number of fragments existing on a straight line defined by the viewpoint and a predetermined point within the 3D scene to be rendered for each pixel of the rectangular image;dividing a two-dimensional region in a screen coordinate system corresponding to the rectangular image into a plurality of regions; andperforming a predetermined rendering calculation for generating the rectangular area where each of the plurality of regions is taken as one unit of calculation, wherein the processor divides the two-dimensional region into the plurality of regions by at least one dividing line so that a difference of summations of the number of fragments included in each of the plurality of regions after the division becomes a minimum.
