가상환경을 이용한 다양한 응용분야에서는 체감에 의한 실재감을 처리하는 것이 요구되고 있다. 체감의 효과를 표현하기 위한 일반적인 형태는, PhanTom에서 사용 가능한 햅틱 라이브러리를 사용하지만, 고비공과 처리 속도 문제 때문에 그 사용의 한계를 가진다. 본 논문에서는 햅틱 렌더링의 근본적인 문제인 실시간 렌더링 문제를 극복하기 위한 비선형 보간에 의한 근사 방법을 제안한다. 제안하는 방법은 하이브리드 접근 방식으로, 캐릭터에 작용하는 동역학적 움직임을 햅틱 효과 생성을 위하여 기하학적으로 재구성함으로써 체감효과 생성에 필요한 시간을 최소화 할 수 있다. 본 논문의 결과로는 캐릭터의 빈번한 제어에서 발생되는 체감 효과를 빠르게 생성할 수 있음을 보이며, 안정적이면서 그럴 듯한 효과를 생성할 수 있음을 보인다.
