Reloading data files: With this release, we now support refreshing or forcing a reader to reload all data files. Mesa 13.0 is now used in Kitware’s Linux distributions of ParaView to benefit from significant speedups resulting from optimizations to Intel’s OpenSWR engine. The default setting for this is to have “Use Data Partitions” set to off since in general the partitions will not coincide and the rendered view will be incorrect. This option requires that all visible data sets in the view have the same partitioning in order to get the rendered view correct. This can dramatically increase the parallel rendering performance. For unstructured grids and polydata this option will skip the redistribution of points and cells of a data set that was previously needed in order to properly perform depth-sorting for correct rendering. When rendering semi-translucent geometry in parallel, added a new option called “Use Data Partitions”. Mixed multiblock and composite dataset rendering with the OpenGL2 backend is significantly faster than in prior releases. The left portion shows the equivalent volume representations. This mode makes use of the GPU-based volume rendering’s independent component support and computes a magnitude array automatically behind the scenes.įigure 2: (From left to right) The two images on the left show a surface representation of the Magnitude and Y-component of a vector field (coordsX * iHat + 10 * coordsY * jHat + coordsZ * kHat).
There is no longer a need to use an intermediate Calculator filter to compute these quantities. Volume rendering by vector components and vector magnitude is now available for structured data when using the GPU-based volume rendering mode. Improvements to VTK’s GPU volume mapper prevent seam artifacts due to discontinuous sampling when doing parallel volume rendering. Of particular interest is that this is VTK’s first volume rendering option that enables volumes to cast shadows, albeit only in non-distributed memory cases.įigure 1: OSPray volume rendering enables shadows. The performance falls between VTK’s own fixed point CPU and GPU enabled volume renderers.
#PARAVIEW RESAMPLE WITH DATASET FULL#
In 5.2 we fixed a number of reported bugs, updated from OSPRay version 0.10.0 to 1.1, and gained full access to OSPRay’s volume rendering. ParaView’s Intel OSPRay-based ray traced rendering backend, which was introduced in 5.1, continues to mature. Molecule rendering saw numerous improvements, including color legend support, custom atomic radii, and the ability to color atoms by arbitrary scalar arrays. Hidden line removal is available for rendering only the nearest portions of a wireframe model. It can be enabled by checking “Use FXAA” in the Render View section of ParaView’s general settings. Major highlights in this release include: New Rendering FeaturesĪnti-aliasing is now available in ParaView. The full list of issues addressed by this release is available here. Note that the output of this last filter is not anymore of "multiblock" type but is now of "UnstructuredGrid" type.ParaView 5.2.0 is now available for download. To circumvent this behavior, I have to apply the Merge Blocks filter after step 1. If the two datasets come from two separate UnstructuredGrids (no multi-block) structures, the Append Attributes is available and I can do what I want.
