Paper Abstract

Virtual human is widely used in educational, entertainment, and 3D game software. In this paper, the subsumption architecture, which is popular in robotics, is employed to make a two-level control model. With this model, virtual human can realize collision-free navigation in a dynamic environment. As collision avoidance is realized in the 0-level layer, path planning is completed in the 1-level layer. Finally, an experiment was done in our human animation platform. And the result shows that this control model can guide digital actor navigate collision-freely in the environment with dynamic and static obstacles.
