"True" lighting in GMT?

Hi @eelcodoornbos thank you very much for the links to the scripting tutorials. After a quick glance at some of these videos it seems I’m in for one steep learning curve. But boy are the scripting possibilities powerful!

While I understand only some of the science behind your visualizations I really like the aesthetics of your work. Clean, crisp, no eye-candy. That visualization of Earth’s magnetosphere in the first Daedalus video looks like straight out of the National Geographic Magazine in the Sixties or Seventies. Nice style. Thank you for sharing it.
