new map generator

@ich

oh there are plenty of links to applets and half assed descriptions of how to do it, but go looking for a detailed description and all i've ever gotten is cryptic source code, if that

i dont like the very short edges that you get with voronoi, so im sticking to the segments between the triangle centers

@llamabeast

those regions are not necessarily provinces, they are meant to be the building blocks of the provinces. im thinking that province edges could be either the gray or red lines, depending on the terrain that has been placed. but im pretty sure that im sticking to rivers on the triangle edges, using the others would make it too chaotic. and yes, getting the delaunay triangulation to wrap was rough.

Oh, you don't want the cells to be the finished provinces, okay, you're free to do that. Otherwise I'd assume that you get strange effects because I'd assume that the game interprets the provinces as being voronoi cells, so that mouse-clicks on the map can be efficiently calculated to the province they're meant for, by only saving and using one point per province instead of a whole polygon.

I still guess there's quite alot of good software around, but either you'll have to program the stuff yourself or use some library which does tons of other algorithmic geometry stuff aswell (like CGAL), yeah.

actually i think the game just gets the closest point. otherwise youd have to calculate the voronoi every time the map is loaded and store all the vertexes in addition to the province centers.

[lch]

Yes, of course it only has to calculate the closest white points of the map, that's what I meant regarding that it does not have to save and use the whole polygons. But it can only do this because that is exactly the defining attribute of voronoi cells.

hmmm... never thought about it like that.

just wanted to post a little demo of the river algorithm im working on
