Support for vector visualisation

✨ Feature Request

Hi again :smile:

Are there any functions/methods in geovista that make it easier to transform vector-representing data, such as wind components, and visualise them on a sphere (ideally on an unstructured grid too)?

Motivation

As I mentioned in another issue (#15), I would like to visualise output of LFRic on a sphere, including the 3 standard wind components.

A while ago I wrote a simple function to convert u, v, w-cubes from the UM output to a pyvista mesh, so I was wondering if geovista would provide the same functionality.

Thanks in advance.

Hey @dennissergeev,

I'm also plumb in the space of playing with LFRic UGRID data, so we're completely in the same domain.

As per #15, totally yes, this is most definitely in the pipeline for sure... but not just quite yet, as there is a tonne of fundamentals to mature in geovista before we get to that point.

Perhaps we could hangout over a virtual coffee sometime? I think that would be super useful. Ping me at the Met Office and we can take it from there (if that helps?)

[dennissergeev]

That's great, thanks!

I'd be happy to chat, though I'm not at the MO (I work at the university) - so perhaps over zoom/teams?

Hi @bjlittle and @dennissergeev I'm super interested/keen in seeing vector visualisation for u, v and w on the LFric grid.

Motivation

The NAME model (NAME on github) will be moving NWP forcing model from the UM to LFric. As part of this work we would like to visualise the LFric wind vectors (rather than u,v and w scalars) to check that the wind vectors are consistent with the dispersion of material from the NAME model.

Just to copy my quick & dirty script with a naive attempt at this: https://gist.github.com/dennissergeev/4cb8a4773f6d08c88ce4241dfe568236

Ping @pp-mo and @stephenworsley

Fancy getting involved?

I think this is perfect for you guys 😉
