Spherical Geometry coding challenge

Today Simon tried the Spherical Geometry coding challenge from Daniel Shiffman’s awesome channel. It involved programming a globe in Processing (using Java), using trigonometrical equations with longitudes and latitudes.

Here Simon explains the equations:

And shows them inside the code:

And here’s how the challenge went on further:

This is the way the globe looked at the beginning:

Daniel Shiffman explaining the trigonometry behind the longitudes and the latitudes:

Simon got stuck in the middle of the challenge, but made it quite far.
