We present an adaptive octree based approach for interactive cutting of deformable objects. Our technique relies on efficient refine-and node split-operations. These are sufficient to robustly represent cuts in the mechanical simulation mesh. A high-resolution surface embedded into the octree is employed to represent a cut visually. Model modification is(More)
We propose an approach for the interactive simulation of deformable bodies. The key ingredient is a threefold representation of the body. The deformation and dynamic evolution of the body is governed by a cubic background mesh. The mesh is hierarchically stored in an octree-structure, allowing for a fully local adaptive refinement during the simulation. To(More)
Efficient approximate deformation models allow to interactively simulate elastic objects. However, these approaches usually cannot reproduce the complex deformation behavior governed by geometric and material non-linearities. In addition, objects having slender shapes require dense simulation meshes, which necessitates additional computational effort. We(More)
Ionic liquids (IL) and hyperbranched polymers (HyP) represent new classes of non-volatile selective solvents. By measuring vapor-liquid equilibria (VLE) of azeotropic and close boiling systems in the presence of ionic liquids or hyperbranched polymers, separation factors are derived and the potential of using IL and HyP as entrainer for extractive(More)
Data-driven methods have received increasing attention in recent years in order to meet real-time requirements in computationally intensive tasks. In our current work we examine the application of such approaches in soft-tissue simulation. The core idea is to split deformations into a coarse approximation and a differential part that contains the details.(More)
