Abstract

In this paper, we model the downward collision of a falling object to the base. We aim to provide maximum diversity of response to physical. collision. To this end, the primary design concern of the model is to unfold the collision phenomenon in a logical and natural manner, detailed enough to construct an immersive virtual environment. To achieve these requirements, first we determine domains for the characteristic of the material of the falling objects, and select the dominant force of the collision. We formulate the collision phenomena with combination of primitive attributes and their relationships. The formulated function evaluates the results of the collision in qualitative aspects as well as in quantitative aspects. Between the collision issues, 'Collision Detection' and 'Collision Response', this paper focuses on Collision Response issue.

본 논문에서는 지표면을 향해 낙하하는 자유 물체의 충돌 현상에 대해 모델링하고자 한다. 이를 위해 최소한의 근원적인 요소를 찾아서 최대한의 다양성을 제공하고자 한다. 몰입감있는 가상환경 구축을 위해 보다 사실적이고 논리적으로 동작하는 충돌 현상을 표현하는데 설계의 초점을 둔다. 이를 위해, 낙하 물체의 재료(material)적 특성에 대한 범위(domain)를 결정하고 우성력(dominant forte)을 선택할 것이며, 힘과 지표면에 대한 모델링을 구축할 것이다. 이는 충돌 후 발생하는 결과들을 정량적인 면뿐만 아니라 정성적인 면에서도 충족시킬 수 있다. 아울러 기존에 많은 연구가 진행된 충돌 검출 보다는 충돌 반응 양상에 모델링의 초점을 둘 것이다.
