An Approach of Mocap Data-driven Animation for Virtual Plant

Abstract

Animation of virtual plant is a hot issue both in computer graphics and virtual reality. In this paper, the motion capture (mocap) is used for plant motion data acquisition, and a motion capture data-driven animation approach is presented. A maize plant is used as an example. First, a scanned data-based virtual model is created. And then, several typical passive motions of the plant such as “swing” and “dragging” are captured by a motion capture device. By means of a proposed mapping and deformation algorithm, the motions are reconstructed and the animation is implemented. The experiments show that the method is an effective and robust approach for animation of plant. Finally, the main contributions and limitations are discussed, and future works are introduced.
