In this paper we present an optimized view-dependent meshing framework for adaptive and continuous level-of-detail (LOD) rendering in real-time. Multiresolution triangle mesh representations are an important tool for adapting triangle mesh complexity in real-time rendering environments. Ideally for interactive visualization, a triangle mesh is simplified to the maximal tolerated perceptual erro...

A cut-cell adaptive method is presented for high-order discontinuous Galerkin discretizations in two and three dimensions. The computational mesh is constructed by cutting a curved geometry out of a simplex background mesh that does not conform to the geometry boundary. The geometry is represented with cubic splines in two dimensions and with a tesselation of quadratic patches in three dimensio...

3D laser scanners become more and more popular especially for measuring construction sites, in the field of architecture and for preservation of monuments. As these scanners can only record discrete data sets (point clouds), it is necessary to mesh these sets for getting closed 3D models and take advantage of 3D graphics acceleration of modern graphics hardware. The meshing process is a complex...

In this paper, we present a novel process of creating hexahedral meshes for the turbomachinery secondary air system. The meshing process is automated from the geometry import to the mesh setup and requires minimum human interventions. The core of the process is a hexahedral meshing algorithm with a boundary layer mesh automatically created. The hex meshing algorithm combines the pave-sweep, gen...

numerical analyses have shown that successful flow simulations and the accuracy of solution noticeably depend on the number of nodes used in computational meshing. a suitable meshing should have the capability of adapting with main flow parameters. because the number of total nodes that can be used in numerical simulation is limited, making such grid for complex flows is almost difficult, if it...

Efficient and accurate space-charge computations are essential for the design of high-brightness charged particle sources. Recently a new adaptive meshing strategy based on multigrid was implemented in GPT and the capabilities were demonstrated. This new meshing scheme uses the solution of an intermediate step in the multigrid algorithm itself to define optimal mesh line positions. In this pape...

Currently the focus of research and development effort for new meshing technology is on developing new algorithms for meshing. As a result of this some successful meshing algorithms have emerged, but true automeshing is still elusive. The generation of a meshed model ready for analysis is more involved than merely creating elements. Solid models created in CAD systems often need to be processed...

In the field of bio-mechanical simulation, the complexity of the 3D models are usually high and require extensive calculations in order to apply the physics over the simulated objects, but also it requires a minimum error in the mesh displacements calculations. This makes the simulation of soft-tissue a delicate process where there is a trade off between speed and precision depending on the des...

Meshing tools are extremely complex pieces of software. Traditionally, they have been built in a one by one basis, without systematically reusing already developed parts. The area has matured so that we can currently think of building meshing tools in a more industrial manner. We propose a layered product line architecture for meshing tools that can be instantiated with different algorithms, wa...
