Abstract: To simulate realistically the scene including large-scale motional roles in real-time, proposes a visualization method based on dynamic texture. The roles motional procedure is rendered to Dynamic-Texture using Render-to-Texture technology. Dynamic-Texture is a kind of texture whose content can be updated in runtime. The roles motion is defined via motion-transferring based on the rotate angles of joint-points. The curve-skeleton model is adopted to deform the motional characters. Each character is exhibited using Billboard in 3D scene. GPGPU(General Purpose on GPU) technique accelerates the image deformation and the scene-rendering. The method can render the scene containing ten thousands of motional characters in 30FPS. It has been proved feasible and valid to improve the rendering efficiency for large-scale motional scene.
