Automatic Generation of Pixel Art Images Based on Contours of 3DCG

Abstract

It takes time to design pixel art images which are used in games because of trials and errors. Expertized knowledge and techniques are also required. In recent years, it is needed to generate various kinds of pixel art images as well as animated pixel art images. We propose an automatic generation method of pixel art images from 3DCG models in order to improve the efficiency of pixel art image design. In pixel art images, contours are dominant. We have developed a new method to detect contours automatically and precisely from 3DCG models, and darken these detected contours. Our method generates pixel images efficiently.
