I am looking for a way to display a 3D rotating ball on the screen, similar to a liquid magnetic compass works:
(Example Liquid Magnetic Compass (https://www.bargainboatbits.com.au/images/products/NAVIGATION/BBB-SC010-50MM-COMPASS-BRACKET-MOUNT-BLACK.jpg?Action=thumbnail&Width=682&Height=682&algorithm=proportional))
I am able to draw a static ball onscreen (who am I kidding it's just a circle...), but I have no idea how I would go about creating a 3D effect (it will be on a black background so can't use shadow) and making it rotate to display different information on different parts of the 'ball'.
There will be horizontal lines across the ball, to act like a scale, which may help with the effect.
Has anyone done anything similar and would be able to recommend how to get started? Any pseudo code would be hugely appreciated!
a search for "arduino artificial horizon display" might get you some info.
Thanks for the info groundFungus, its not quite what I'm looking for but its on the right path, thanks!
