The LEM is suitable for real time simulation and virtual environment interaction. The approach implements a static solution for elastic global deformation of objects filled with fluids based on Pascal's Principle and the volume conservation. The volumes are discretised into long elements, defining meshes several order of magnitudes smaller than tetrahedral or cubic meshes. We show how these volumes are constructed when the method is applied to a general mesh. We also propose a method for collision detection when two such objects interact. Finally, we show how we can perform dynamic simulation when the physics of the objects are modeled using bulk variables: pressure, density, volume and stress. This approach is particularly interesting for real time simulation of soft tissue undergoing small deformations. 2014-03-29T04:47:28Z 2014-03-29T04:47:28Z 2001 Working Paper IEEE International Conference on Intelligent Robots and Systems, vol. 4, 2001, pages 2196 – 2201 0-7803-6612-3 http://dspace.unimap.edu.my:80/dspace/handle/123456789/33197 http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=976396&queryText%3DAn+approach+to+LEM+modeling%3A+construction%2C+collision+detection+and+dynamic+simulation 10.1109/IROS.2001.976396 en IEEE Conference Publications
