I love a slice movie 💛 one of the least-exciting (but most informative) post-pro techniques that you’ll ever use. That said, we can do a lot with one line, here’s a simple example… Location annotation for an animation

Note: If you must use more than a single line of code (&/or you want to use some external Python modules) then you should check out the raw scripting power of the Programmable Annotation instead.

It updates whenever the data or the time step change, so we can set it & forget it, confident that it will always be up-to-date. With that one line we can grab data from our model, do all manner of calculations, combine it with other strings & format it to our liking, before writing the output into the scene as a regular text object. The Python Annotation sits somewhere in-between, blessing us with a single line of Python code to create our annotation. There are a bunch of ways to annotate your scene in ParaView, from a simple text source, all the way up to “beast-mode” a.k.a. Let’s get into it & then you can go and give it a try… Python Annotation So, whether you’re looking to annotate a property in an animation, or you want a label that’s synced to your current dataset, then this filter has you covered. It’s a quick introduction to ParaView’s Python Annotation filter, a neat (but not new) way to create dynamic annotations that are always up to date.

Use shfill shading operator (PostScript only): From the gl2ps documentation: Using shfill enhances the plotting of smooth shaded primitives but can lead to problems when converting PostScript files into PDF files.It’s Robin from CFD Engine & if you’ve ever had to re-do an image (or a series of images) because you forgot to update an annotation 🤦‍♂️ then this email’s for you.

Enabling this will ensure that text will appear exactly as shown in ParaView - without it, the appearance of text will depend on the fonts available to the viewer/printer.

Render text as paths: If checked, any text is explicitly drawn into the image using Bezier paths, otherwise the text is embedded as raw character data to be rasterized by the viewer/printer.

2D primitives and text objects will be rendered as vector primitives on top of the rasterized image, which may cause some depth sorting issues. This produces lower quality output for these primitives, but is necessary for more complex scenes (e.g.

Rasterize 3D geometry: Renders the 3D primitives and surfaces in the scene as a rasterized (i.e.

Cull hidden primitives: Reduce the size of the exported file by completely ignoring any primitives that are clipped or obscured by other geometry.

Draw background: Use the background color of the scene/chart as the background of the image.

This reduces the file size on disk using a lossless compression algorithm. Compress output file: Produce a gzip'd file.This will produce the best results, but can be slow and use a lot of memory. BSP sorting: Use a binary space partitioning algorithm to sort the primitives.Simple sort: Fast sorting method that gets most things right, but may incorrectly order objects in certain conditions.No sorting: No sorting is performed - primitives are exported in the same order that they are drawn in ParaView.When in doubt, select "Simple sort" for 3D scenes, and "No sort" for 2D charts. Since vector graphics formats don't consider depth in their drawing commands, it is essential to properly sort the primitives so that they render correctly.

GL2PS depth sort method: How to sort the depth of the graphics primitives in the exported image.This is used for the image metadata, and is unrelated to the filename. Plot title: Name of exported document.Configure the export options in the window that pops up (note that not all options are available for all formats):.

Enter a file name and select a vector graphics format (see list above for full list).

If multiple views are open, make the one you wish to export active by clicking in it.

This functionality has been restored for later versions. Note that the ParaView 5.0 release does not support vector export when using the OpenGL2 backend. This new functionality uses gl2ps to generate the following formats:

In ParaView 3.98, the ability to export 3D scenes and 2D charts as publication-quality vector graphics was added.
