Abstract: An information display controller is capable of switching a plurality of screens and allowing a display to display the plurality of screens thereon, and includes a screen constructor, a texture atlas storage unit and a texture atlas creator. The texture atlas creator creates a texture atlas, in which elemental images as constituents of the plurality of screens are arranged, in accordance with an algorithm that takes sizes of the elemental images as references. The texture atlas storage unit stores the texture atlas created by the texture atlas creator. The screen constructor constructs the plurality of screens by using the elemental images extracted from the texture atlas stored in the texture atlas storage unit. In an event of creating the texture atlas, the texture atlas creator preferentially incorporates, into the texture atlas, an elemental image for composing the screen including more elemental images already arranged in the texture atlas.

Abstract: Provided are a texture atlas generation unit (10) that generates a texture atlas (41) by combining a plurality of textures, and generates position information (32), in the texture atlas (41), of a texture to be rendered; a polygon information storage unit (330) that stores polygon information (33) in which are set vertex coordinates of the polygon in an output image (42) and vertex texture coordinates corresponding to the vertex coordinates in an image to be rendered on the polygon on the basis of the texture to be rendered; a pixel coordinate calculation unit (22) that detects locations of pixels to be filled in with the polygon in the output image (42), and calculates pixel-corresponding texture coordinates corresponding to locations of pixels in a rendered image; and a coordinate conversion unit (23) that converts the pixel-corresponding texture coordinates to coordinates within an area of the texture to be rendered on the texture atlas (41).
