![]() Meshes from scratch: vtkTemporalUGWavelet / Temporal Unstructured Grid Wavelet There is also a specific source in the plugin, that lets you generate static In the EnSight format, there is no way to detect if a dataset is actually static or not, so the user should choose by checking, or not, the `UseStaticMesh` checkbox. Note that, for now, only unstructured grids or multiblocks containing a single unstructured grid are supported in input.Ī SMO implementation of a reader uses a similar mechanism, as it will generally only read the geometry the first time it is executed, and then only read the data associated with the following time steps and update it on its cached geometry.Ĭurrently, only a single reader is supported by this plugin:ĮnSight Reader, in all its versions: 6, 6Binary, Gold and GoldBinary. vtkUnstructuredGridGhostCellGenerator / Generate Ghost Cells (only available if `PARAVIEW_USE_MPI` is ON).vtkDataSetSurfaceFilter / Extract Surface (used internally by ParaView for the rendering).Of course, this can provide huge speedups when used right.įor now, the following filters are supported by this plugin: A static filter can detect if its cache has become invalid by using the GetMeshMTime(), in that case, the cache will be recomputed. It will then only compute the point, cell and field data and set it on the cached geometry. Surface Filter without static mesh optimization Surface Filter with static mesh optimization ImplementationĪ SMO implementation of a filter typically uses a cache to store the geometry. On the Filters side, we consider the modification time of the dataset in order to know if the cached mesh needs to be recomputed. Only the point, cell and field data will be read. When executed with other timesteps, this cache will always be used (unless some parameters change), saving the reading and the mesh construction time. On the Readers/Sources side, we make sure to create the geometry only once and store it in a cache. This plugin addresses the case of static meshes by replacing certain readers and filters by their own SMO version operating with static meshes. Of course, this can provide huge speedups when used right (see the benchmark section). In that case, the cache will be recomputed. ![]() A static filter can detect if its cache becomes invalid by using the GetMeshMTime() method. It will then only compute the data and attach it to a shallow copy of the cached geometry. However, you can easily think of a typical case of static mesh slicing: the slice geometry will not change over time, only the attached data (point, cell or field data) will change, so you could avoid the computation time linked to the slice geometry computation.Ī static mesh optimized (SMO) implementation of a filter typically uses a cache to store the geometry. Note: The terms mesh and geometry will be used interchangeably. Currently, there is no specific handling of this case in ParaView/VTK filters, and thus they recompute everything when the time step changes. The aim of this plugin is to optimize post-processing and visualization time of transient datasets with static geometries. A screenshot from a temporal dataset with a static geometry from Code_Saturne Postprocessing of temporal dataset with static geometry is wide spread in several physics domains like CFD and mechanics. Yet by a simple analysis of the shattering dimension, we show that they do not.Kitware has just released the StaticMeshPlugin for ParaView ! Clone and compile it from here. ![]() And one may expect that these may materialize in the size of the composition theorem. For Fréchet variants, there are \(\varTheta (2^k2^m)\) valid alignment paths in the free-space diagram. While the VC dimension bounds for the discrete Hausdorff and Fréchet metric balls may seem like an easy implication of composition theorems for the VC dimension , we still find three things about these results remarkable:įirst consider the valid alignment paths in the free-space diagram: those are all sequences of cells which are monotonic in both coordinates, their first cell contains (0, 0), and their last cell contains (1, 1). ![]() A range space \((X,_m^d\) and a range set of the form
