Flat to 3D
24/33
Combined change images
The start
  • • The images need to wrapped around a sphere
  • • Some tricky 3D rotation required
  • • Say hello to the POV-Ray ray-tracer
  • • Zoom and rotation follows an "interesting" formula
  • • Lower layer is a Earth map
  • • Transparent "changes" layer
  • • I also add atmosphere and some other effects
