An algorithm to detect collisions between both rigid and deformable objects is presented. The approach exploits benefits of a bounding volume hierarchy (BVH) and a feature-based method. The BVH decomposes the three dimensional polygonal objects into a hierarchy of spheres. The lowest level of the hierarchy is formed utilising spheres which bound 1-rings surrounding each vertex of the original mesh...
This article proposes a methodology to study coarticulation in sign language. Our aim is to provide information in sign language (SL) thanks to a displayed signing avatar performing SL predefined animations. Therefore, we explain the approach we have chosen to model coarticulation, and animate our avatar. We also propose a definition of what coarticulation is, based on an overview of the literature,...
In this paper, we propose a new process for sign language synthesis. Our approach is based on a geometric description of signs to animate a signing avatar. We work as follows: the signs are divided in timing units and treated separately in a sequential process. The final results are merged into a global animation file describing the whole sign in terms of articulatory angles for a skeleton.
