Abstract

Recently, public interest in virtual reality (VR) and augmented reality (AR) has increased. Therefore, computer graphics-related research has been actively conducted. This has included research on virtual space related to human posture implementation. However, such research has focused on general posture in humans. This paper presents a system with reference to the basic posture in sports climbing and the inverse kinematics method for generating the positions and behavior of virtual characteristics in a three-dimensional virtual space. The simulation based on the inverse kinematics method, produced with an inverse kinematics solver and initial pose animation from motion capture, provides realistic and natural movement. We designed a simulation system to generate correct posture and motions similar to those in sports climbing by applying the basic procedure of sports climbing. The simulation system provides help for producing content about sports climbing, such as learning programs for novice climbers and sports climbing games.

최근 가상현실(VR, virtual reality)이나 증강현실(AR, augmented reality)이 주목받으면서 이에 관한 컴퓨터 그래픽스(computer graphics)연구들이 활발히 진행되고 있다. 특히, 인간의 동작을 가상의 공간에서 구현하는 방법에 관한 연구들이 활발히 진행되고 있다. 하지만 많은 연구가 인간의 일반적인 동작에 한정되어 있다. 본 연구에서는 역운동학(IK, inverse kinematics)을 이용한 스포츠클라이밍 자세생성과 동작제어를 통해 인간의 일반적인 동작 이외에 스포츠클라이밍과 같은 특수 목적의 다양한 동작들을 삼차원의 가상공간에서 가상 인물(virtual character)의 자세 및 동작을 생성하는 시스템을 제안한다. 역운동학(IK, inverse kinematics) 기법을 통한 자세 생성은 역운동학 함수(IK function)와 실제 데이터를 통한 기본자세 애니메이션을 제작, 이를 활용하여 사실성을 더하고 자연스러운 자세 및 동작을 생성한다. 본 논문에서는 스포츠 클라이밍의 기본동작을 이용하여 올바른 자세와 함께 실제와 유사한 동작을 생성하는 시스템을 설계하였다. 이를 통해 클라이머를 위한 학습 프로그램이나 클라이밍 게임 같은 다양한 형태의 스포츠 클라이밍 콘텐츠를 제작하는데 도움이 되고자 한다.
