3-D CG lighting with an interactive GA

Abstract

This paper applies an interactive GA technique to support lighting design of 3-D CG. Five amateur CG designers decide the best types, ON/OFF, color attributions, and positions of three lights in 3-D CG for a given object to match different two given motives. They make the lighting by hand and by using the lighting support system based on the interactive GA. 20 subjects compare their lighting arts, and a subjective test is conducted to evaluate how the interactive GA is useful. From the subjective test, it has been shown that the CG lighting support system especially helps lighting designers who are beginners.
