Artistic Expression Design and Implementation of Human Walking for 3D Computer Animation

電腦動畫人物走路的藝術表現設計及製作

摘要


3D場景中虛擬人物行走的重要性與困難度順理成章的使得人類走路動作的模擬成為電腦動畫研究的顯學。然而已發表之研究多致力於擬真或時效的改善,對於動畫師的藝術設計議題則付之闕如。本篇論文研究探討電腦動畫人物走路的藝術表現設計及製作,文章首先簡述人物走路動畫的困難與現狀,繼而探討動作設計與各類動作控制技術相關文獻,並提出一個普遍適用的走路動畫模擬架構,再對動作設計策略逐項分析探討;其中以動畫準則中有關動作表現的部分來確認動作的擬真自然,並以步伐決定因素來控制走路動畫的多樣化個性。最後總結所提出的人物走路動作藝術表現設計策略及模擬架構作為本文的結論。

The significance and difficulties in human walking have made it one of the most popular research areas in computer animation for years. However, most of these published works have been focused on realism or time improvement. The issues of animator's artistic control of human walking are seldom addressed. This paper devotes on artistic expression design and implementation of human walking for 3D computer animation. It first describes the problems and current status of human walking. After briefly reviewing the motion design and animation techniques, a general framework for animating bipedal walking is proposed. Then motion design strategies of human walking are suggested. Among these guidelines, animation principles are applied to examine the realistic look of animation. Followed by some important gait determinants which resolve the characteristics of various walking. Finally, the discussions of our motion design and implementation strategies are offered as the conclusions.
