Photorealistic cloth in real-time applications


Young-Min Kang, Tongmyong University, Busan, Korea.



In this paper, we propose an efficient and stable animation and rendering method for complex mass-spring-based cloth model for interactive applications. Although the mass-spring model can be easily constructed and simulated, it is well known that the model suffers from the instability problem. The method proposed in this paper employs the harmonic oscillation model and analytically integrates the force for better stability and accuracy while keeping the integration scheme still explicit. As the integration scheme is explicit, the method can be easily parallelized, and the performance improvement can be easily obtained by exploiting the parallelism in the graphics processing unit. For the realistic representation of virtual clothes, we also proposed an efficient and effective rendering method for woven surfaces on the basis of alternating anisotropic reflectance and microfacet distribution function rotation.
