RESUMO

Currently, physics-based models are frequently used for cloth simulations. There are basically two approaches: particle mechanics and continuum mechanics. The particle mechanics is at the present time the most widely used method, having some advantages like an easy formulation and a high performance. The continuum mechanics is regarded as being a more precise approach, but it has a high computational cost. This low performance is mostly owing to the numerical solution that obtains cloth states along the time, because its formulation is based involves a large number of variables. The solutions found in the literature are the finite element and the finite differences techniques, with the semi-implicit and implicit integration. They possess a non linear computational complexity. So, this work aims to analyze the suitability of application of an explicit integration technique, that has a linear behavior, to a cloth model founded on the theory of Cosserat surface, whose authors claim to have proved it can produce natural folds under pure compression forces. Based on this evaluation, the Verlet method was selected and a rectangular mesh dynamics simulator with an interactive graphics interface has been implemented. This permits a practice validation of the cloth model, showing its superiority on production of folds compared with the other models
