Terrain Synthesis is my personal white whale of terrain generation, and an integration into World Machine would bring the software up to a whole new level IMO.
If you don’t know what terrain synthesis is, here are some examples:
As you can see methods like this could bring World Machine to a whole new level.
At the moment the sketch based editing with Layout Generator is very hard to get right, but with terrain synthesis you could achieve very believable and most of all stylistically consistent and accurate results.
I know this topic has come up a few times here on the forum, like way back in 2007 http://forum.world-machine.com/index.php?topic=765 but with the time more and more research papers about terrain synthesis have come up, showing stunning end results, but afaik no commercial software yet has any sort of terrain synthesis available.
Here for example is a paper from 2012 http://ai2-s2-pdfs.s3.amazonaws.com/44b2/7a07be8bd721e27ed561ac8e3b72a26ae7b6.pdf
Lots of texture artists are already starting to use very advanced synthesis methods to produce lots of new textures from photo reference, especially with the rise of neural networks and machine learning.
Here is an example
I know Stephen has probably already an opinion on terrain synthesis in World Machine, but maybe if the community shows some support on this idea he will rethink about it.
