Point-Based Methods in Shape Modeling and Physical Simulation

Опубликовано 6 сентября 2016, 5:39

Point-based methods have a long history in graphics for rendering, but their use in modeling and simulation is more recent. Shape representations based on sampled points faithfully reflect several 3-D acquisition technologies and point-based techniques can provide a flexible representation of geometry for situations where forming and maintaining a complete mesh can be cumbersome or complex. This talk will briefly describe some current work in simulating wide area contacts, large-scale deformation and fracture, collision-detection, and qualitative shape analysis of point-sampled data -- all carried out using meshless methods. The irregular and dynamic sampling these applications require creates new challenges and leads to methods with a distinctly more combinatorial and topological character.
