It doesn’t take very long to make the computer randomly generate a design, but it does take a while to make it look just right. I spent many months fiddling with the algorithm, starting over at least twice, before I settled on the current design.
There is a lot of math going into these designs. It takes 23 random numbers to generate these imaginary solar systems using only 5 parameters.
How it works
First I pick a page size
The sun size gets selected from a range
The orbits are generated until they run out of page space
Then the planet sizes are set based on the orbit gaps to be sure they fit
