Interactive Evolution of 3D Models based on Direct Manipulation for Video Games
Du-Mim Yoon, Kyung-Joong Kim · Procedia Computer Science · 2013
Interactive evolutionary computation (IEC) is an effective solution for problems of user subjectivity. However, a significant problem with IEC is user fatigue. IEC requires direct evaluation, and so increasing the number of generations results in increased fatigue. We previously reported a method for building a three-dimensional (3D) model using interactive evolution. Here, we propose a method of direct manipulation (DM) using IEC to reduce user fatigue, whereby direct encoding is applied to the final results during post-processing. This allowed instant changes to the shape of the final model, reducing user fatigue. This method can manipulate several parameters of 3D models in real-time. Test results show that IEC with DM is superior to IEC alone. © 2013 The Authors. Published by Elsevier B.V. Selection and/or peer-review under responsibility of the Program Committee of IES2013.
