Many virtual environment applications incorporate avatars as some of their inhabitants. Interactions between avatar and surrounding objects, as well as avatar and avatar, need to be done in real-time in order to retain the degree of realism and immersion of the virtual environment application. In this study, we consider an avatar as a human-like, 3D hierarchical representation. The aim is to improve the collision detection process involving a human-like avatar and its interaction. Previous work on avatar collision detection is presented. A proposed improvement is summarized from methods that have been implemented in other fields like ray-tracing and deformable objects simulation that can also be beneficial for this purpose.
