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...
Understanding information graphics rely on thought process of graphics' reader, and thinking has the most important role in interpretation and exploitation. We are interested in the cognitive mechanisms underlying interaction with information graphics. In this study, we studied those cognitive processes which are employed when interacting with information graphics. Based on these experiments, we have...
