• Backface culling of Earth countries and provinces not working properly.

    From Skybuck Flying@21:1/5 to All on Tue Aug 9 08:02:09 2022
    I found this dataset first because I was searching for JSON file format:

    https://github.com/martynafford/natural-earth-geojson

    It seems to be a conversion of version 4 of this github repository, but I am running into a problem:

    I am trying to render polygon lines in such a way that only the front of the sphere/globe is showing, but some parts of the backside is also showing, I am not sure why this is, perhaps an issue with the input data ? or perhaps the conversion process ? or
    perhaps some issue with GLScene or OpenGL ?

    I could try and read the dbf file to see if these backface culling problems are caused by the conversion, or if this is simply part of this dataset, and I will try and use version 5.

    Bye,
    Skybuck.
