The standard instructions apply with some additional instructions for building the script generator plugin. This requires building from source as of ParaView 3.14.1. The first requirement is to have a ParaView client which can export the Python script.

The animation support is fairly rudimentary and also doesn't optimize memory usage. So depending on what actions you perform you might end up with all data steps loaded in memory at the same time. If you have sequentially numbered files in a format that ParaView can read (e.g. Menu option and check if ParaView recognizes the sequence as a Group : ) then loading these as a time-varying dataset is easy. You can unfold the group by using the little triangle, to check if ParaView detects the sequence correctly: The current animation time is controlled from the tool bar at the top: If you click OK with the group selected a single reader will be added to the pipeline, that will process the sequence of files on demand. Even though the example above uses steps that are larger than 1 (i.e.The sequence detection in the Open File dialog is automatic, but you can still load a single time step if needed: simply unfold the group and select the specific file you want to load.Initially, only the first time step is loaded, but if you change the time the corresponding data file will be loaded (if not already loaded). ) ParaView still assumes the files form a sequence. Depending on how you structure your file names this might or might not be what you want. The time file associated with each loaded data file is, by default, derived from the index in the sequence.If you need more control over the sequences then use a PVD file, as described in the next subsection. So in the above example the file sequence would have times 0, 1, 2, 3. Some file formats fail to load (or won't vary over time) as sequences.In case you want to associate different time values you can use a PVD file as well. Most notably polygonal file formats like. More control over sequential data reading and time values You can work around this by converting these files to ParaView polygonal files (, see the Python snippet below). There might be situations where the default sequence detection of ParaView is not good enough. For example, you might have stored a large set of sequential files, but only want to visualize each N-th file. Or you might to want to set more meaningful time values for each time step. Sometimes the sequence detection also simply fails to work, especially when the file name part is only numbers without any prefix. Using a PVD file can be a good option in these cases. A PVD file is a lightweight XML-based file, which references one or more files holding the actual data to load. In its simplest form, listing a sequence of file name + time stamp pairs, a PVD file can look like this:įor each of the data files some metadata can be specified that ParaView uses. Obj file (containing polygonal geometry) to a ParaView. A PVD file can be easily generated using a (say) Python script, e.g.The file path is relative to the PVD file.Writer = CreateWriter("/home/./output/file%04d.vtp" % i) vtp fileįilename = "/home/./input/file%04d.obj" % i There are further options per DataSet that are described in the PVD page linked tecting all files in a given directory and writing a PVD file referencing all of them.
