I'm currently looking for a way to bring together by experience with #SmoothedParticleHydroynamics and #remoteSensing, and as part of this process I also wrote a converter (in #Julia, because this has to fit within some existing code which I wrote in that language) that allows me to export satellite imagery as #VTK unstructured grids, so that I can visualize them in #ParaView
It feels weird because ParaView *really* isn't suited for #GIS work, but in this case it turns out to be The Right Tool For The Job™.

I was making great progress on a probably-useless #python #vtk #dataviz and had gotten to the critical step: compute the intersections of these #3d polymeshes to show the interesting part.....
...and it keeps segfaulting.
Internet suggests the polymeshes may be imperfect but cleaning them doesn't help. I'm dejected. I wanna work on it but I don't want to spend most of a weekend debugging a single problem

I love #pyqtgraph for 2D scientific and #dataviz #graphs in #python. And now I'm starting to really love #vtk for 3D.
It has a lot of the same #science adjacent type plotting. It works well with python. (And there's a #javascript #api but I haven't used it...yet). And it is *extremely fast*.
The only problem is that there's a lot to it and I don't really understand the workflow. (I feel like there's an extra layer. There's a "source", a "mapper", an "actor" and a "renderer". One of those seems superfluous.)
There are a lot of examples on their site and elsewhere. And there's a lot of documentation. But I haven't yet found a good combination tutorial that has worked examples that are also explained.
I really just have to use it more and get it into my head.
Fortunately, I have a weird #math/#geometry/#orbitalmechanics thing I want to try to solve (or at least visualize). Intersections of multiple ellipsoids and cones....

#dataviz is critical, but I don't think in pictures, I think in spatial relations and movement (is this an #adhd thing?)
Movement happens in time and you usually want to viz the time axis all at once, so I've trained myself to turn "$variable vs t" into mental motion
Other times you need an interactive #ux and that usually means 3D
I love love love #pyqtgraph for #python plotting but they will be the first to tell you the 3D needs some love
My punfully-named work project has proved to be a hit[1] and I managed to get an 30y-experienced #software #developer *with an #astronomy degree* assigned to it. (This is a #space application)
She agreed that the 3D portion was neat but hard to use. She found #vtk, which seems to be the perfect partner because it does 3D really well, stays out of 2D and has a #pyqt connector.
I just worked through a tutorial and, yeah, this could be a huge breakthrough in my viz apps.
[1]They think they want to change the pun name but they are wrong. An unforgettable name is money in the bank.

This is an attempt to create a metal/steel-like material... and in order to add a bit more appeal on top, I also tried to mimic a not yet fully polished 'function surface/coating'. The model is a low-poly mesh from Sketchfab https://lnkd.in/e2xCdwJh Yes, the mesh is a bit odd... the wall-thickness between the cylinders is too thin to make sense in the real world... and it is missing coolant passages. #vtk #shader #pbr #rendering

Cutting/clipping with vtk 9.4.0 *sigh* sure it's only a low-resolution data-set, but it looks horrible with this vertex-based coloring... it's going to be some work to patch this to make it use proper interpolation using a fragment-shader based approach #OpenGL #vtk #dataViz #computerGraphics

After more than 15 years i am stepping into the world of vtk again... 9.4.0 to be precise, which was just released about two weeks ago. Let's see what changed, what remained the same and what was added. #computerGraphics #vtk #OpenGL

~fluencyCAD~
Progressed into sketch projection from and to 2D. I think this is a cleaner approach for drawing.
Next stage will be additional operations like cutting holes and timeline logic.
Intention is to have CAD geared towards maker with a focused UI with static layout so you can develp "muscle memory".
I´m pretty happy already as I completely ruled out writing a CAD software at all.Project can be assisted by donating for tea here:

@cosmoscalibur Hmmmm....I've rejected #vtk more than once over the years as being overkill. But the amount of kill I need has grown, so maybe it's time to make the jump. #matplotlib is definitely not cutting it anymore.

current #SearchEngine results are frustratingly poor for "medical imaging", "learn medical imaging", "medical imaging for software engineers", etc.
They tend to focus on commercial companies, paid college degrees, and machine learning.
Yet another reason I'd like to build a better search engine. 🙂
BTW, if you happen to be working in #MedicalImaging with programs such as #VTK or #ITK, I'd love to follow you!

#FreeCAD's HarryvL has added the (WIP) #FEM/#FEA critical plastic strain ratio as a post-processing step for #CalculiX results. This is available from the #VTK pipeline + for export to #ParaView.

In case you wonder how we programmed our stuff in #C++ on #SGI IRIX: We actually avoided #IRISPerformer after 1995.
For many applications, we used a #3DGraphicsFramework called #VTK on top of #GL and later #OpenGL.
