Abstract

We present a real-time simulation method for muscles which are actuated by skeletal structure based on anatomical properties of the muscles. Muscles are designed by their two endpoints attached to either bones or other muscles and their volume are preserved approximately during the deformation. Skin deformation animation is obtained by a simple skinning due to the muscle deformation. We present also the performance data for a human-like multi-linked character which has bones, muscles, and skin. According to our experimental result, we can get skin deformation animation with a few tens of muscles in real-time. The method proposed in this paper can be applied to obtain skin deformation animation for multi-linked characters appear frequently in real-time environments such as games.

본 논문에서는 실제 근육의 해부학적 특징에 근거한 모델을 설계하고, 근육의 모양이 골격의 움직임에 따라서 변화하는 실시간 시뮬레이션 기법을 제시한다. 근육 모델은 골격 혹은 다른 근육의 양 끝 점에 부착되는 위치와 방위에 따라서 부피가 유지되도록 변형된다. 근육 변형의 결과는 간단한 스키닝을 통해서 실제 피부 변형의 결과로 이어져 관찰된다. 실제 인체와 유사하게 모델링된 다관절 캐릭터의 수행 성능을 제시한다. 실험적 결과에 따르면 수십개의 모델링된 근육을 골격 운동에 따라서 실시간에 변형할 수 있다. 따라서 빠른 수행속도에 일정한 품질을 요구하는 게임 등과 같은 실시간 제어 환경에 등장하는 다관절 캐릭터를 제어하는데 효과적으로 사용될 수 있다.
