INFORMATION DISPLAY CONTROL SYSTEM AND TEXTURE ATLAS CREATION METHOD

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.
