From 1kx1k to 4kx4k and the rendering speed goes from 5 minutes to 240 minutes? That's about a 50x increase in time for 16x the number of pixels. Processes like river finding and random Poisson fill aren't exactly linear in scaling so that's not too bad.
I would recommend using a slightly smaller font on the map description. It looks very cramped in there.
It's not quite as good as it sounds. A lot of my processes are linear; they take up quite a bit of the 5 minutes but very little of the four hours. The most time-consuming part of the 1k x 1k run is calculating the initial coastline which (for legacy reasons) I was never able to optimize away; it's linear and goes from about two minutes to just under an hour. The Poisson fill places the same number of trees at any resolution, so it's linear (and only a fraction of a second in any case). The basin-filling is slowed down the most by far. I do two passes, as recommended in one of your Wilbur tutorials, the first taking more time; at 1k x 1k, the longer of the two takes about twenty seconds, but at 4k x 4k, it's over two hours. (Basin fill should be about cubic in linear resolution, or about 64x for this increase, not 320x.)Originally Posted by waldronate
In before the buzzer!
Looks like I got in before the contest closed. As suggested above, I've reduced the size of the text in the cartouche. There's probably all sorts of other tweaks I could make, but I think I'll leave it at this.
Thanks again to everyone who offered praise and criticism. This map isn't quite of the level of the others in the Challenge, but it'll certainly not be my last.
I love the simple style of this map, with hints of sophistication (the mountains!) lurking here and there. When the task at hand is presenting information clearly and deliberately, this map gets it done very well. Good job!
