![]() ![]() Your desktop installation of ParaView should match the version you are running on the LC cluster. The instructions below will walk you through this setup. Because of the firewalls at LLNL, you will have to establish an SSH tunnel to carry the data from the "listening server" to the client on your desktop. ![]() The heavy lifting is done on batch nodes of an LC cluster. The client runs on your local desktop and uses your graphics card to display images quickly on your computer. ParaView can be run from laptops up to sophisticated and complex computers and workstations, and is one of the best software programs on the market that deals with large data visualization.The figure above shows a pictorial representation of ParaView as run in parallel at LLNL. In conclusion, ParaView proves to be an advanced and reliable data analysis and visualization application, which is suitable especially for power users. An overall powerful and efficient CAD app line, plane, sphere), annotate data in the 3D scene, create animations by recording a series of key frames, make use of comparative views mode for displaying results from a parameter study, and create visualizations of large data sets that reside on parallel and remote systems (client, data server and render server combinations). Last but not least, you can work with 3D widgets (e.g. Several tools are implemented in the program for helping you create a custom filter, add camera link, manage plugins, record and play a test, open up the Python shell, as well as import macros from Python scripts. Additionally, you can make the app display them in an alphabetical order. Calculator, Slice, Clip, Contour, Threshold), Data Analysis, Material Analysis, Quadrature Points, Statistics, and Temporal. You can choose between a wide range of filters that you can apply to your data, and there are organized in different categories, namely AMR, CTH, Common (e.g. There are many objects that you can place in the working environment, such as 2D glyph, 3D text, arrow, axes, box, cone, cylinder, disk, hierarchical fractal, line, plane, ruler, sphere, and hyper tree grid. The statistics inspector reveals details about the memory used by every pipeline filter or source, while the memory inspector gives you the power to keep an eye on ParaView’s memory usage during interactive visualization through direct queries to the operating system. The tool reveals several handy features in the Information panel, namely file properties, data statistics (type, number of cells and points, memory), array data (association, name, type and range of each array in the dataset), bounds (coordinates and dimensions), timesteps (index and value of all time steps available in a file), extents (only for structured datasets), as well as data hierarchy for AMR and multi-block datasets. General information, statistics and memory inspector You can take screenshots and save them to PNG, BMP, JPG, PDF or other file format, export the current scene to EPS, PDF, PS, SVG or POV file format, save animation to OVG, PNG or AVI, as well as export geometry to PVD. ParaView is able to read data from a comprehensive number of file formats, such as INP, CML, CSV, TXT, DEM, DCM, FLASH, NCD, VTK, RES, OBJ, XYZ, DAT, PHT, SAR, RAW, DUMP, JPG, VRT and WIND. The Properties panel enables you to tweak any given module within the pipeline and the View area is displayed in one or more windows. It integrates a multitude of dedicated parameters and configuration settings, so reading the help manual and experimenting with the built-in features can get you out of trouble.įile and Filter menus give you the possibility to open files and manipulate data, while the Pipeline browser is used for revealing the pipeline visualization. The tool sports a clean and user-friendly layout with well-organized commands in the main window so you can quickly process data. Datasets consist of mesh (topology and geometry) and attributes. The utility uses the Visualization ToolKit (VTK) libraries where data objects can be scientific datasets (rectilinear grids or finite element meshes) or abstract data structures such as graphs or trees. The analysis of large datasets is done via distributed memory computing resources. In order to visualize your data three steps need to be followed: reading, filtering and rendering. ![]() Processing scientific dataĭuring a visualization process the program takes raw data and converts it to an understandable format in 2D or 3D space, more specifically a visualization pipeline. ParaView is an open-source software application that makes use of qualitative and quantitative techniques in order to explore large sets of data in an interactive 3D environment or programmatically using scripting and batch processing capabilities. ![]()
