Broad-leaf Virtual Plant

Virtual plant plays key roles in Virtual Reality. And efficient and realistic animation constitutes important foundation of it. This paper proposes a new modeling and animation method of broad leaf plant. It shows how to use a physically based animation method to realistically model the 3D foliage of plant with thickness information and to emulate the movements of stem and foliage in wind. In order to achieve fast collision detection we propose a suitable non-hierarchical spatial decomposition structure combined with oriented bounding boxes (OBB) for deforming broad leaf plant that can be constructed in a preprocessing phase, and then updated efficiently during the animation.
