Regular grid slice extraction.
I added an example of the regular-grid-in-space time-dependent wavefield extraction in the examples subdirectory. Please check it out and let me know what you think. You can either visualize the wavefield directly in the notebook (example given) or in Paraview by opening the .vti
file series (also given). The latter is probably more useful for full volume renderings on GPU-accelerated Paraview instances -- the in-notebook visualizing via xarray is actually pretty neat already!
