Interim update. Now working on positioning spheres - motion, tilt and rotation: that's just easy trigonometry.
Earth tilted and rotating.
Interim Video - Earth tilted & rotating
The Earth here is rotating the wrong way round - a change of sign is required.
At present I'm still using the 16-image NASA data for the inputs. The image joins are improved but still not perfect.
Now just have to get the Earth to move around the Sun by Newtonian gravitation, and the Moon to move around the Earth (keep same face to Earth).
Great fun!
