This is really awesome. Do you think it will work with Tyler.jl? |
@lupemba I'm going to be working on that sometime this month :D - just got Tyler to support GeoMakie (though interactivity is a bit buggy). The challenge here is that you have to figure out the intersection of the camera's view frustum (essentially a "pyramid section" along the central axis) with the sphere, and then figure out which lat/long area is visible. This is solveable, of course, but tricky, so it will be some time until I can figure out exactly how to solve that. Once that is done, then Tyler will work with this, but will have "holes" at the poles beyond -85 and +85 degrees latitude. That's an inherent limitation of the Web Mercator crs, so we'll just have to deal with it I suspect. |
TODO: set poly_convert to subsample here.

This PR builds towards a 3D Globe Axis, that currently will accept a Geodesy.jl datum as the ellipsoid definition, and try to work in ECEF coordinates. We can add more functionality, integration with CoordRefSystems.jl datums, etc later.
This axis will:
More todos to come. This is an expansion of the Geodesy.jl approach that was taken previously
