We propose an example-based approach for simulating complex elastic material behavior. Supplied with a few poses that characterize given object, our system starts by constructing space of prefered deformations means interpolation. During simulation, this example manifold then acts as additional attractor guides the object towards its shapes. Added on top existing solid simulation codes, potential effectively allows us to implement inhomogeneous and anisotropic materials in direct intuitive...

Abstract Finite element simulations in computer graphics are typically based on tetrahedral or hexahedral elements, which enables simple and efficient implementations, but turn requires complicated remeshing case of topological changes adaptive refinement. We propose a flexible finite method for arbitrary polyhedral thereby effectively avoiding the need remeshing. Our elements harmonic basis functions, satisfy all necessary conditions FEM seamlessly generalize both linear trilinear elements....

We present a method that brings the benefits of physics-based simulations to traditional animation pipelines. formulate equations motions in subspace deformations defined by an animator's rig. Our framework fits seamlessly into workflow typically employed artists, as our output consists curves are identical nature result manual keyframing. Artists can therefore explore full spectrum between handcrafted and unrestricted physical simulation. To enhance artist's control, we provide transforms...

We develop an accurate, unified treatment of elastica. Following the method resultant-based formulation to its logical extreme, we derive a higher-order integration rule, or elaston , measuring stretching, shearing, bending, and twisting along any axis. The theory accompanying implementation do not distinguish between forms different dimension (solids, shells, rods), nor manifold regions non-manifold junctions. Consequently, single code accurately models diverse range elastoplastic...

We present a method for controlling the motions of active deformable characters. As an underlying principle, we require that all be driven by internal deformations. achieve this dynamically adapting rest shapes in order to induce deformations that, together with environment interactions, result purposeful and physically-plausible motions. Rest shape adaptation is powerful concept show restricting suitable subspaces, it possible explicitly control motion styles Our formulation general can...

We present a method for simulating highly detailed cutting and fracturing of thin shells using low-resolution simulation meshes. Instead refining or remeshing the underlying domain to resolve complex cut paths, we adapt extended finite element (XFEM) enrich our approximation by customdesigned basis functions, while keeping mesh unchanged. The enrichment functions are stored in textures , which allows fracture discontinuities at resolution much finer than mesh, similar image increased visual...

Selective repeat automatic-repeat-request (ARQ) protocols for use in a point-to-multipoint communication over broadcast links are considered. In this context, new approach called XOR strategy, based on the selective strategy capacity enhancement of channel, is suggested. The idea to physically combine several blocks negatively acknowledged (NACKed) by different receivers XORing (i.e., modulo 2 addition) minimize number retransmissions and increase throughput. Five implementations pure...

We propose a simulation technique for elastically deformable objects based on the discontinuous Galerkin finite element method (DG FEM). In contrast to traditional FEM, it overcomes restrictions of conforming basis functions by allowing elements with weakly enforced continuity constraints. This added flexibility enables arbitrarily shaped, convex and non-convex polyhedral elements, while still using simple polynomial functions. For accurate strain integration over these we an analytic...

Abstract We present an example based geometry synthesis approach for generating general repetitive structures. Our model is on a meshless representation, unifying and extending previous methods. Structures in the output are converted into functional where functions defined by point locations attributes. then formulate as minimization problem patches from function matched to those of example. As compared existing structure methods, new algorithm offers several advantages. It handles discrete...

Wind and Solar photovoltaic power plants outputs are usually highly variable due to gusts of wind sharp sun irradiance level variations caused by cloud shading effects. These effects negatively impact system security, especially in weak networks. On the other hand, recent technological progress cost reductions, electrical energy storage systems an attractive alternative that can be easily integrated into non‐despatchable compensate for those output fluctuations.
