First of all thank you to the Plotly team for developing Dash! Its awesome.
I am a mechanical engineer by trade but build a few apps here and there to package analysis / data processing tools. Before Dash I was using pyqtgraph to build small apps, but delivering through a server using Dash allows a much wider audience.
I was pretty excited when I heard about Dash-vtk. A few years ago I dabbled in python-VTK (with pyqtgraph) to create a tool to visualize / post-process structural analysis results (unstructured grid mesh) without the expensive commercial solver.
Dash has been my recent go-to for all other apps so I thought I’d see if dash-vtk could work for my use case (specifically unstructured mesh grids with cell scalar data). I didn’t notice any unstructured grid examples so I want sure unstructured grids would be supported.
Long story short: dash-vtk works for unstructured grids out of the box and it feels very smooth. I wrote up a little Medium article walking through an example. Check it out or just check out the associated github repo for the example.
