Anima: uma técnica para criar animações a partir de imagens estáticas em jogos.

Abstract

One of the challenges in creating games is to make the graphics of a game as attractive as possible for its players. Thus, to make a product successful, it is necessary to invest time and resources to make the graphics attractive to potential players. A common API (Application Programming Interface) in games is OpenGL [1] which is used to render 2D and 3D graphics. Developers interact with the GPU using OpenGL functions and GLSL[1] (OpenGL Shading Language) commands. In this work, we create and describe a distortion technique to transform still images into animations, focusing on simulating the effect of imperfections in hand-made animations. In addition, we evaluated the technique through a survey using a modified version of a commercial game we are developing and found that 96.7% of respondents prefer images with the technique being applied and 93.3% responded that they feel more confident when drawing with the technique being applied.
