View Full Version : Automatically generated maps.

01-19-2012, 07:01 PM
Hi folks.

I'm in the process of writing an application that generates maps typically used in fantasy settings.

I'd like to inform you of my blog which is located at http://generated-worlds.blogspot.com/

I encounter totally different problems from those of you who are artists and handcraft your maps, so if you're interested in seeing my results, and
my challenges along the way, please stop by. And, I'm no real cartographer, so there's a ton to learn; I appreciate constructive feedback. Always.

I'm also posting about my progress at Google+ (https://plus.google.com/u/0/107616160909727474904/posts)

Happy mapmaking.

Looks very intriguing. I'm interested to see what the generated rivers look like.

01-20-2012, 02:35 PM
Yeah, the rivers are quite a challenge!

01-23-2012, 04:16 PM
I just added a short blogpost, showing off early attempts at rivers. For those interested, please take a look :)

02-01-2012, 06:01 PM
Looking good, end result is something I will look forward to :)

02-02-2012, 03:38 PM
Thanks! I'm going to try to notify of updated here as well.

I just added another post, showing off some screenshots of rivers, now with tributaries :)

Today I added landmass textures, and i posted a screenshot on the blog. As I say in the blogpost, this is just the first iteration of many, but I'm feeling a bit giddy, - I think the result is very promising.

Check it out here http://generated-worlds.blogspot.com/2012/02/starting-with-theming.html and leave some feedback if you feel like it :)

Interesting idea. I wish you great success in your endeavour. :)

06-20-2012, 03:00 PM
hmm.. it looks like we share the same objective! i am mainly interested in the exercise of procedurality, or as you say "people who need a new world NOW" (lol)

after that, i had to stop looking ;)

These maps look great - i like the idea of a 2-step algorithm to determine city locations. Very cool. I subscribed to the blog and hopeto comment if i find the time!

Looks like a very interesting project. The results seem very promising. Keep at it!

Nice blog! The material is probably more suited for the general discussion subforum rather than resources, so I've moved the thread here.

06-26-2012, 06:11 AM
A fascinating undertaking you've got there!

06-27-2012, 06:25 AM
hey cool... i'm looking for an autmatic world generation component to integrate in my RPG-Master-Online-Tool i'm working on...

Not to awaken an old thread for the sake of doing so, but I just wanted to let anyone interested to know that after a rather long pause in the project, it's back on track again, and moving forward! The maps keep getting better and better, and hopefully I'll be able to release something to the public "soon". I've spent much time cleaning up code lately, as the project has grown in size and complexity, but I finally feel in control again :)

Is this like what one would get by using a product like Fractal Terrains?

10-26-2012, 07:54 AM
I haven't really used Fractal Terrains, but as far as I understand it, fractal terrains produces landscapes based on fractals, and stops there? I see that fractal terrains can produce equirectangular projections though, which is cool (so you can easily wrap them around 3D spheres). My software does not do that. I produce "flat" maps, but in addition to producing landscapes, I also include rivers, textures (forests, deserts, etc), and cities. I'm also in the process of implementing more political functionality. The map software can distinguish between the different continents, islands, oceans etc, - allowing me to give them their own names, and perhaps a color hue. Fractal terrains seems pretty cool, but I hope to go some way beyond.

Nice blog thanks for sharing!!!

Wow great looking maps.

Curious what the lines in the water are though? They mainly appear just off the coast. Are they continental shelf lines or such or just a byproduct of the code?

The lines in the water is just the result that is produced with a given water-texture. My "usual" water texture doesn't produce them ;)

I just released an early demo version that showcases parts of what I've managed (and obviously what I haven't!).

If you want to have a look, and try it, you can download it at: https://sites.google.com/site/genworlds/

It only works on 64-bit windows for now, unfortunately.

Some have reported an error after map generation is finished, but in those cases the maps are still produced and located in C:\Temp\

ill try that once i get home from work. always interested to try out generators

02-26-2013, 05:36 PM
There was an error in the demo earlier, which is now fixed! Here are two maps generated from this build.

(They had to be downscaled to fit the file-size limit here, so the quality is not 100%).

A little update. I just added functionality for seamlessly stiching maps together into indefinitely large maps. So now you can create maps as big as you please :)
The blog har more details, but I'm pretty psyched at least!

03-14-2013, 09:16 PM
Good on ya for the zoom feature! That's typically how I build: broad strokes so I have a concept of how everything fits together, then fine detail for individual places/cultures.

Hey, I should have also added - make your blog address your signature so folks can quick link back to it :)

03-15-2013, 04:48 AM
Thanks! And good idea about the signature :)
