[Abstract]:The force feedback technique is introduced into the virtual rendering process, and a new brush modeling method is proposed. Real-time simulation of brush deformation and ink transmission between pen and paper in Chinese painting and calligraphy drawing process. The geometric model of brush is constructed through central skeleton and surface structure. The center of brush is simulated by spring oscillator model under the action of force. Frame bending deformation and brush surface deformation. Dynamic control of brush deformation by force. Simulation of ink and ink transmission between pen and paper in painting drawing process by real-time calculation method of brush ink quantity. Based on hardware component HPxw8600 workstation and Phan. Tom. Desktop force feedback equipment. A virtual rendering system with force feedback technology is constructed, in which the user realizes real-time rendering through Phantom Desktop force feedback device, which enhances the reality of the virtual rendering process.
