Rule-based camerawork controller for automatic comic generation from game log

Abstract

We propose a rule-based camerawork controller for a recently proposed a comic generation system. Five camerawork rules are derived through an analysis of online-game webcomics about Lineage 2, one rule for each of the five event types: chatting, fighting, moving, approaching, and special. Each rule consists of three parts relating to the three camera parameters: camera angle, camera position, and zoom position. Each camera-parameter part contains multiples shot types whose value indicates the frequency of their usages in the analyzed webcomics. In this paper, comic frames generated with the proposed camerawork controller are shown and compared with those generated with our previous controller based on heuristic rules, confirming the effectiveness of the proposed camerawork controller.
