Working with Earth data on a 3D globe #18142

@vijaysm / @iulian787 have some cool ocean data, recMeshOcn128.h5m.gz. Its 3D data on a sphere representing the surface of the earth. Its just the oceans so there are holes in the mesh where the continents are. Its also a really cool hexagonal sampling of a sphere.
We'd like to be able to use VisIt's Cartographic projection operator. But, that operator works only for 2D, structured meshes where the coordinates are latitude and longitude. I was able to cobble some operations together involving several instances of Transform operator, 3D_globe_to_cartographic.session.gz, but once there, applying Cartographic projection operator has no effect. It looks like VisIt's Cartographic projection operators require the input mesh to be a structured grid. That is also impacting this. I think VisIt winds up doing a no-op but also not issueing an error message as to why. I have no idea why structured grid is a reqirement here in VisIt currently.
