Hello there. I'm new to the group but have followed your TerraPOV articles with
interest. I don't know if TerraPOV is still a current project, so I borrowed
your most recently posted code and did some test renders with different
environments. Hopefully I'm not rediscovering the wheel.

The attached scene was traced from the surface of the planet at 2m elevation
facing sunwards: heading zero and sun elevation of -1 degree. I'm unsure if this
shows that TerraPOV is working or if it's a 'feature' of it. The scene is your
code with a cloud sphere at 5km altitude and a textured moon (true scale) at a
15 earth radii distance.

Test renders from satellite altitude look visually correct when compared with
NASA orbital images so your code seems quite accurate so far.

Thanks.
j.
