Model Design And Implementation Of Deformable Character Behavior

Although, Many works have been done on simulation of deformable character behavior, Many problems remain in academic and industry circle, such as lack of authenticity, slowness of simulation and non-cooperative motion. In this paper, we mainly studied physics-based simulation of deformable character behavior.First, we studied physics-based simulation of non-human-like character behavior. Based on classical Mass-Spring model and daily observation, we presented a novel page-flipping simulation method. Through three major improvements, this method naturally allows us derive a grid-based semi-implicit integration scheme that has conditioning independent of the magnitude of paper. We further recorded the key frames of the rendering to get a faster repeated simulation.Secondly, we studied simulation of human-like character behavior using Skinned Mesh Animation. Based on skeleton-skinning system and FEM method, we developed a new skeleton-driven physics-based simulation algorithmThirdly, based on our simulation algorithm, we designed a skeleton-driven physics-based simulation framework. We test it through experiment. It can produce deformation of skin according to movement of character. At last, we got a faster repeated simulation by applying Key Frame method.Through experiments, it has been proved that our simulation techniques can produce fast, authentic effects.
