While the Lagrangian Finite Element Method (FEM) is widely used for elasto-plastic solids, it usually requires additional computational components in the case of large deformation, mesh distortion, fracture, self-collision and coupling between materials. Often, special solvers and strategies need to be developed for a particular problem. Recently, the hybrid Eulerian/Lagrangian Material Point Method (MPM) was introduced to the graphics community. It uses a continuum description of the governing equations and utilizes user-controllable elasto-plastic constitutive models. The hybrid nature of MPM allows using a regular Cartesian grid to automate treatment of self-collision and fracture. Like other particle methods such as Smoothed Particle Hydrodynamics (SPH), topology change is easy due to the lack of explicit connectivity between Lagrangian particles. Furthermore, MPM allows a grid-based implicit integration scheme that has conditioning independent of the number of Lagrangian particles. MPM also provides a unified particle simulation framework similar to Position Based Dynamics (PBD) for easy coupling of different materials. The power of MPM has been demonstrated in a number of recent papers for simulating various materials including elastic objects, snow, lava, sand and viscoelastic fluids. It is also highly integrated into the production framework of Walt Disney Animation Studios and has been used in featured animations including Frozen, Big Hero 6 and Zootopia.","PeriodicalId":268479,"journal":{"name":"ACM SIGGRAPH 2016 Courses","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114062245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, ergonomic and technical limitations of existing devices make this a challenging endeavor. In particular, it is necessary to design novel efficient real-time computer vision and computer graphics algorithms, and create new lightweight forms of interaction with the environment through small form-factor devices.

There are, however, a variety of discrete representations of tangent vector fields on triangle meshes, and each approach offers different trade-offs among simplicity, efficiency, and accuracy depending on the targeted application. This course reviews the three main families of discretizations used to design computational tools for vector field processing on triangle meshes: face-based, edge-based, and vertex-based representations. In the process of reviewing the computational tools offered by these representations, we go over a large body of recent developments in vector field processing in the area of discrete differential geometry. We also discuss the theoretical and practical limitations of each type of discretization, and cover increasingly-common extensions such as n-direction and n-vector fields. While the course will focus on explaining the key approaches to practical encoding (including data structures) and manipulation (including discrete operators) of finite-dimensional vector fields, important differential geometric notions will also be covered: as often in Discrete Differential Geometry, the discrete picture will be used to illustrate deep continuous concepts such as covariant derivatives, metric connections, or Bochner Laplacians.","PeriodicalId":268479,"journal":{"name":"ACM SIGGRAPH 2016 Courses","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128379250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
