The most visible change to ParaView users from this upgrade is the addition of volume rendering to the OSPRay path tracer backend. OSPRay version 2 consolidates volume sampling responsibilities to the new OpenVKL thread and SIMD accelerated “volume kernel library” library. ParaView 5.9’s version of Intel OSPRay has been updated from 1.8 to 2.4 and NVIDIA’s visRTX has been updated accordingly. Rendering enhancements Ray tracing updates The drawback is that preselection behaves slightly differently with translucent geometries (only visible faces of the cells are selected) and high order cells (all subdivisions are visible). This is a lot faster than interactive selection extraction, especially for big datasets. When enabled, the preselection reuses visible geometry to display preselection.
Fast preselectionĪ fast preselection option is available in the render view settings. If Python2 support is still required, please use ParaView 5.8 or an earlier release. Python2 reached its end-of-life on 1 January 2020 and its final release occurred in April 2020. To use system MPI implementation instead of the one packaged with ParaView, pass –system-mpi command line argument to any of the ParaView executables. Compatible MPI implementations are listed here. ParaView binaries can now be used on linux systems with MPICH ABI compatible MPI implementation. Using MPICH ABI compatible implementation Pass –mesa with optional –backend to any of the ParaView executables to request Mesa3D-based rendering with appropriate backend. ParaView binaries now respect command-line arguments instead to indicate if Mesa3D libraries should be loaded for software rendering, instead of using OpenGL libraries available on your system. On linux, paraview_mesa launcher has now been removed. If contiguous mode is used for the 5 ranks and 2 displays example, the displays are assigned as 0, 0, 0, 1, 1. Accepted values are ‘contiguous’ and ’round-robin’. –displays-assignment-mode= argument can be used to customize this default assignment mode to use a contiguous assingment instead. Thus, if there are 5 ranks and 2 displays, the displays are assigned as 0, 1, 0, 1, 0 sequentially for the 5 ranks. These displays (or devices) are then assigned to each of the ranks in a round-robin fashion. pvserver -displays=:0,:1,:2įor EGL, these can be EGL device index, e.g.
–displays= can be used to specify a comma-separated list of available display names, for example: >. To make this easier, we now have two new command-line arguments added to pvserver, pvrendering and pvbatch executables. When multiple GPUs are available on a system, you must set either the DISPLAY environment variable or the EGL device index for each ParaView rank correctly to ensure that a rank uses a specific GPU. Choosing DISPLAY or EGL device using command-line arguments The design discussion for this feature is available at ParaView Discourse. Refer the ParaView Guide for details on how to use these extractors. Instead of using a separate control panel to define parameters for extracts, one now simply uses the Properties panel the same way it is used to change properties on readers and filters. This has evolved from the Extracts Inspector that was introduced in earlier versions and which has now been entirely removed. With this release, we introduce a new pipeline object, called Extractor, to enable saving data and image extracts from the pipeline. To save images or data from ParaView, one typically uses File > Save Data or File > Save Screenshot. The full list of issues addressed by this release is available here. Major changes made since ParaView 5.8.0 are listed in this document.
