In the previous post of this series:
- a simple grid consisting of points on the surface of a sphere was built step by step to approximate Earth.
- the basics of matrix rotations were reviewed to obtain:
- the tilt of the rotational axis.
- the changes in the orientation of the tilt relative to the Sun as Earth revolves around it over the year.
The closing figure in the first post is copied here as it summarizes visually all the relevant results and describes the starting point on top of which this post will build the calculation of the daytime by latitude througthout the year. This post will also cover how to prepare the data so that it can be easily plotted.
