Abstract

To generate foot–skate free locomotion along user defined path for virtual actors, a novel data structure of contact–based motion graph is proposed. At first, sample motions are divided to contact clips according to the number of feet in contact with the ground. Then a directed graph can be built by producing nodes and basic edges based on these clips. After generating edges between nodes from different samples by linear interpolation, the contact–based motion graph can be defined as a strongly connected component of this graph. Applying synthesis strategy designed for nodes and edges, a path on contact–based motion graph can be converted to a smooth foot–skate free motion moving along the given path. The following experiments show the effectiveness of this method.
