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.

 

Keywords: contact-based motion graphs; locomotion synthesis; virtual actors; foot-skate free locomotion; directed graph; path adaptation; data structure; sample-based; motion synthesis; virtual character motions; virtual characters.
