Hello my fellow Science Fictionists and/or otherwiseians! Wanted to build a space map for my fictional universe and would like to share my various methods of doing so here. As well as garner ideas for how to even start or go about this. Right now I barely know where to begin. My fictional universe contains a massive amount of galaxies involved in the plot. The scale is enormous to say the least. Some individual planets and star systems need to be named, as well as galaxies. I'm thinking of a 2d map of the galaxies only, since that can be printed into the book, but I may also opt for an optional 3d map. Tools: A painting software for the 2d map. Some sort of 3d program like universe sandbox or something else for the 3d map? Methods: For the 2d map I'm thinking of a zoom-able map where all the key planets/stars/galaxies are named. I would need something that could "generate" an entire galaxy, randomly, in a painting software. The entire universe would be seen from one standardised observation point. For the printed version that can't be zoomed to individual planets, only galaxies would be visible and laid out, this is the simplest option and the most appealing one for me, already have a basic sketch of it on an old A4. 3d map using some other type of software, much more complicated. Might not even bother with this. Notes: - Not everything will need a name, only things involved in the plot, of course. - This is set in a fictional universe, our galaxies do not apply. - I have the basic layout of the universe in my head. That's my plan anyway. How would you do it? Thoughts? Opinions? I will share updates with what I may use here so that people may be able to use it in the future.
