Realistic rendering of 3D avatar using physics simulation and minimal sensors

Abstract

Physics simulation o ers the option of truly receptive and realistic animation. Although wide ac- ceptance of physics simulation for the animation, commercial applications still relies on kinematics- based approaches for the animation of actively controlled characters. In recent times, however, research on interactive character animation using simulated physics has resulted in incredible en- hancements in controllability, effectiveness, flexibility and visual fidelity. In this work, the objective is to develop an application to render 3D avatars of users in a realistic way by using the laws of physics to minimize number sensors i.e. using physics based constraints related to animation of the avatars and apply this technique to constrain skeleton(e.g. a knee or an elbow has only some degrees of freedom) for a more realistic simulation. The application is intended for virtual reality based social networking, such that avatars of the networked users can be seen to interact with each other and their virtual surroundings in a realistic manner. We present a structured evaluation of relevant aspects, approaches and techniques followed in the project and conclude by pointing out some open research areas and possible future directions.
