![]() Consider the pipeline in the example above. This also allows us to automatically switch existing pipelines that contain such filters to use the accelerated filters without needing to modify the pipeline. That means that anywhere that the vtkContourFilter is being used, vtkmContour can be used instead and speed up the processing. For example, vtkmContour is a subclass of vtkContourFilter. This is possible because many of the filters in the VTK::AcceleratorsVTKmFilters module are sub-classes of the corresponding filters in VTK. Using VTK Factory to override existing filtersĪ recently implemented method to access the accelerated filters, enables using the VTK factory mechanism to override the existing VTK filters with their accelerated counterparts. Mapper->SetScalarModeToUsePointFieldData() Mapper->SetInputConnection(contour->GetOutputPort()) ImageSource->SetWholeExtent(-EXTENT, EXTENT, -EXTENT, EXTENT, -EXTENT, EXTENT) Įv->SetInputConnection(imageSource->GetOutputPort()) Įv->SetLowPoint(-EXTENT, -EXTENT, -EXTENT) Įv->SetHighPoint(EXTENT, EXTENT, EXTENT) Ĭontour->SetInputConnection(ev->GetOutputPort()) Ĭontour->SetInputArrayToProcess(0, 0, 0, vtkDataObject::FIELD_ASSOCIATION_POINTS, "RTData") The following example pipeline demonstrates the use of the accelerated contour filter ( vtkmContour): vtkNew ren Commonly used filters like Contour, Slice, Clip, Gradient and more are already available in this module. This module consists of VTK filters that are thin wrappers over the corresponding VTK-m filters and can be used in regular VTK pipelines. VTK-m accelerated filters in VTK are available in the VTK::AcceleratorsVTKmFilters module. Using Accelerated filters in VTK Direct instantiation of the wrapper filters We will also provide a brief overview of how one can develop accelerated filters in VTK-m and enable them to be used in VTK and ParaView. In the following sections we will describe how the user can access these accelerated filters in VTK and ParaView. We have been gradually integrating VTK-m filters into VTK and several accelerated filters are available in VTK and ParaView right now. Other features such as the visualization pipeline, rendering, IO, etc, will continue to be provided by VTK and ParaView. VTK/ParaView will use these implementations to accelerate their filters. The goal of the VTK-m library is to provide highly parallel implementations of visualization algorithms that can run on different types of parallel hardware. They are mature tools with an extensive set of features that are beyond the scope of the VTK-m library. ![]() VTK and ParaView are two of the most popular visualization software. The open-source VTK-m library is freely available here. To this end, we have been working on our next generation C++ visualization library, called VTK-m 4, that uses fine grained parallelism to implement high performance visualization algorithms. ![]() Algorithms that are best suited for this kind of architecture are ones that utilize fine-grained parallelism. These devices have smaller processing cores but contain thousands of such cores. Therefore, legacy software, which does not have general-purpose GPU code, is not going to make efficient use of these machines. Instead of the traditional CPUs, the primary source of computing power for these machines are going to be the next generation GPGPUs from Intel, AMD and NVIDIA. The first exascale capable computing machine is here 1 and more are on the way 2 ,3. On the right is the output of the rocm-smi command which is being used to verify that the GPU is being utilized. Crusher is an early access test-bed for Frontier, containing identical hardware and similar software. I suppose I am mixing things up somewhere and I’d be happy about pointers as to where to look.Demonstration of VTK-m overridden ParaView filters running on Crusher. VtkPVPluginLoader (000001D855F1F2F0): The specified module could not be found. Set(CMAKE_RUNTIME_OUTPUT_DIRECTORY "$)ĬMake runs fine and everything compiles but when trying to load the plugin, ParaView throws the error ERROR: In C:\bbd\6c27b535\build\superbuild\paraview\src\Remoting\Core\vtkPVPluginLoader.cxx, line 519 Option(BUILD_SHARED_LIBS "Build shared libraries" ON) The top level CMakeLists.txt contains cmake_minimum_required(VERSION 3.8) │ │ ├── TensirFieldCriticalCellsFilter.xml I have more filters but for the sake of simplicity I’ll only go through one here. The project structure I have so far looks like as shown below. I am currently trying to make the switch from Inviwo to Paraview but the Plugin/module structure seems to elude me.
