^{Originally posted by RichardScottOZ March 25, 2022} Two things I use more and more it seems.

There’s a discussions here:-

https://github.com/pydata/xarray/issues/4470#issuecomment-1068428147

e.g. @banesullivan did an extremely useful https://banesullivan.com/pyvista/examples/raster.html#sphx-glr-pyvista-examples-raster-py [and an earlier version, but I am a big fan of rioxarray too]

and things I have literally done recently:-

to xarray

data = result['density'].reshape(result.dimensions[2],result.dimensions[1],result.dimensions[0])
XC = [result.bounds[0]+200*i for i in range(result.dimensions[0])]
YC = [result.bounds[2]+200*i for i in range(result.dimensions[1])]
ZC = [result.bounds[4]+200*i for i in range(result.dimensions[2])]
da = xr.DataArray(data=data, dims=["z", "y","x"], coords={"z": ZC, "y": YC, "x": XC})

as a quick version

so having this officially integrated where you didn’t have to think about it for various types of things would be excellent.

So where would you start?

A wrap thing and accessors on the other side, or all in that?

I don’t have a good idea of where I would start, yet, PyVista developers might though.

Here’s a start, anyway :- https://github.com/RichardScottOZ/pyvista/blob/feat/xarray/pyvista/utilities/pvxarray.py

Closing now that pyvista-xarray is implemented here: https://github.com/pyvista/pyvista-xarray
