Um estudo comparativo de métodos de simulação de tecidos virtuais através de sistemas de partículas

Abstract

Physically based cloth animation has gained much attention from researchers in the last two decades, due to the challenges of realism and performance placed by the film and game industries, as well as by the applications of virtual reality and e-commerce. Consequently, there have been overwhelming achievements in this area, and several approaches have been proposed for modeling and simulating the dynamic behavior of cloth. Modeling cloth as a mass-spring system has been widely used, because of its simplicity and since it leads to more efficient numerical solutions to the governing differential equations. These numerical integration methods are divided into two main categories: explicit integration methods and implicit integration methods. A deeper understanding about their use in cloth simulations is still in order. Thus, the objective of this work is to analyze the integration methods most commonly used in the literature of cloth simulation, based on particle systems, to understand the advantages and disadvantages of their use. A comparative study of those methods is done, considering the criteria of animation realism, computational effort and numerical stability.
