![]() Far beyond making pretty pictures for publication and outreach, the resulting photo-realism can in some cases be used for direct comparisons between simulation output and observations. ParaView now includes seamless support for hardware-accelerated ray tracing using OptiX, a component of the NVIDIA RTX platform.Īccelerated by the latest-generation GPUs, especially with the RT Cores devoted to ray tracing found on NVIDIA’s Turing GPUs, ParaView brings a wide range of benefits to scientific visualization. ParaView and VTK add GPU-accelerated ray tracing with NVIDIA RTX An example of an Explicit Structured Grid with faults and some masked cell layers. The ExplicitStructuredGrid plugin exposes a source and a set of filters provided to generate such grids, convert to/from Unstructured Grids, and efficiently slice and crop those grids. ParaView can now render explicit structured grids. This dataset enables representation of geological or reservoir grids, for instance, where faults can exist in any direction. These grids allow definition of a dataset where cells are topologically structured (all cells are hexahedrons and structured in i, j and k directions) but have explicit definitions of their geometry. > paraview-mesa -help New Features Plugin for Explicit Structured Grid datasetsĮxplicit structured grids have recently been introduced in ParaView. > paraview-mesa pvserver -backend llvmpipe -server-port=22222 ![]() > paraview-mesa pvserver -backend llvmpipeĪrguments to the ParaView application can be passed with > paraview-mesa paraview -backend llvmpipe Instead of running paraview –mesa-llvm, for example, you now launch ParaView with an auxilliary executable that sets up library paths so that Mesa is used, e.g., ![]() In the linux binaries, the way to use the bundled Mesa libraries for rendering has changed. For details and specific version numbers of third-party libraries that ParaView now depends on, please see the list of updates in VTK and ParaView. ParaView 5.7.0 has the latest known stable versions of third-party libraries. ParaView and VTK depend on a number of open source third-party libraries. A Catalyst edition-like mechanism that enables selective inclusion of the parts of ParaView needed for in situ analysis will be added to a subsequent version of ParaView. This version of ParaView does not support the building of Catalyst editions. Catalyst editions not available in this release Fortunately, most Python scripts generated from ParaView with Python 2 can be ported to Python 3 without much work – many may not require any porting. For example ParaView’s Cinema library had to be updated for compatibility with Python 3. Making the transition exposed a number of lingering issues that we have addressed in this release. Starting with 5.8, only Python 3 will be supported and included with the binaries. ![]() We expect that this will be the last ParaView release to include support for Python 2. For macOS, we are providing binaries with Python 2 only. In this release, we publish Python 3 compatible binaries on for Windows and Linux. ParaView has had experimental support for Python 3 for several releases. Guidelines for updating ParaView plugins and ParaView-basedĪpplications will be enumerated in a future transition guide document. To available CMake options when building ParaView Read more…. Please be advised that these changes have resulted in changes That improves build times as it avoids leaking include paths and minimizes potential for private includes from clobbering other modules. Public dependencies between modules including propagation of include paths. Furthermore, modules now respect private and Now, all of that information is associated with the targets themselves. Following these improvements, developers should see a vast improvement in CMake configure and generate times due to minimizing of the number of generated configuration files that were previously used to track module-related information. The CMake build sub-system for ParaView has been completely redone and updated to effectively use the latest enhancements in CMake.
