Today most cloth simulation systems use triangular mesh models. However, regular grids allow many optimizations as connectivity is implicit, warp and weft directions of the cloth are aligned to grid edges and distances ...

Recent work in the field of medical simulation have led to real advances in the mechanical simulation of organs. However, it is important to notice that, despite the major role they may have in the interaction between ...

In this paper we present a novel multi-layer model for physically-based character skinning. In contrast to geometric approaches which are commonly used in the field of character skinning, physically-based methods can ...

During the past years, first physics engines based on JavaScript have been developed for web applications. These are capable of displaying virtual scenes much more realistically. Thus, new application areas can be opened ...

We prove that the maximum number of intersecting pairs spheres between two sets of polydisperse sphere packings is linear in the worst case. This observation is the basis for a new collision detection algorithm. Our new ...

Considering that humans acting in constrained environments do not always plan according to shortest path criteria. rather, they conceptually measure the path which minimises the amount of expended energy. Hence, virtual ...

In deformable character animation, the skin deformation of the neck is important to reproduce believable facial animation. The neck also plays an important role in supporting the head in balance while generating the ...

In this paper, we explore the use of Adaptively Restrained (AR) particles for graphics simulations. Contrary to previous methods, Adaptively Restrained Particle Simulations (ARPS) do not adapt time or space sampling, but ...

This paper proposes a method to simulate inextensible hair strands using tridiagonal matrix formulation in which distance constraints are formulated as a linear system. The proposed method avoids constructing a full matrix ...

We present the RPI-MATLAB-Simulator (RPIsim) as an open source tool for research and education in multibody dynamics. RPIsim is designed and organized to be extended. Its modular design allows users to edit or add new ...
