[Paraview] reading MATLAB file

Hello, I have some matlab files I’d like to get into PV. Initially, the data is quite simple: sphere centers, radii, color attribute (a few 100K spheres). In the past, I’ve manually converted the files into .vtk formats using Python w/ scipy to load/parse the .mat files. But I’d like to avoid

[Paraview] vtkCutter

Is vtkCutter not directly accessible in PV (from the menus)? I’d like to do something similar to: https://www.vtk.org/gitweb?p=VTK.git;a=blob;f=Examples/VisualizationAlgorithms/Python/ClipCow.py

Re: [Paraview] vtkCutter

Silly me. I see now that it’s just a matter of using multiple Clip filters, using planes with orthogonal normals, resulting in the desired boolean set of points. Still need to figure out how to cap the clipped glyphs though… > On Oct 17, 2017, at 3:55 PM, Heiland, Randy <heil...@iu.edu&

[Paraview] installing additional Python modules

Any good advice for installing additional 3rd party modules for pvpython? In a Programmable Source I’d written to read in MATLAB (.mat) data files, I was using the scipy module (scipy.io.loadmat). When I wrote that, I naively thought to myself - WOW, it sure was convenient that they included

[Paraview] animation: files, pgmable source

I’m probably missing a basic concept and hoping someone can enlighten me. I have a pipeline with a Programmable Source that reads in a (non-VTK formatted) file, I process it and then I have filters in my pipeline that act on that data. I want to be able to feed multiple files to the pipeline,

[Paraview] multiple scalar fields

How does one use 2 (or more) scalar fields in a dataset, e.g. one for a colormap, one to scale glyphs? E.g., Pgmable Source: pdo = self.GetPolyDataOutput() num_pts = 2 newPts = vtk.vtkPoints() cell_color_ID = vtk.vtkFloatArray() cell_radius = vtk.vtkFloatArray()

[Paraview] OSPRay, scaled spheres

Just want to make sure I’m not missing something. In my Pgmable Source PolyData, I render Points and love the OSPRay-rendered spheres. However, is there any mechanism for (independently) scaling these, i.e., other than the fixed Point Size? Or is the only way to get scalar-value scaled spheres

[Paraview] POV Exporter, spheres/geom/colors

I have a simple 2-point Pgmable Source (below) and render it 1) as 2D Glyphs/Vertex (with the nice OSPRay, and scaled spheres), and 2) as various 3D/geometric glyphs. Then I Export the scenes as POV files. Only the geometric (non 2D/Vertex) glyphs generate partially-meaningful POV output.
