Wilbur vs. Terracing

[Michael Morris]

Well, I've begun playing around with wilbur - and I can't get rid of the terraced appearence of the terrain after import. Attached is the png file I am importing and a jpg of what Wilbur is outputting before any operations are applied.

Should be a deterrace tool in there somewhere.

But Waldonrate (writer of Wilbur) is a member here and he should be along shortly to answer your question.

I had a similar problem when importing a regional-scale heightfield from Fractal Terrains. Deterrace worked to a degree, but it took a very long time to do its thing. I also experimented with applying a blur to the heightfield before importing it, and that helped a bit. The problem I had was the small number of levels available in the field. I had to increase the brightness and contrast before blurring in order to get decent results. Even then, I wasn't terribly happy with what I came up with, but I have not had the time to do more experimentation.

I know it's not much of a comfort, but Bryce is even worse for this.

Try Filter>>Fill>>Deterrace followed by Filter>>Blur>>Gaussian Blur with a sigma around 1.0. A straight blur with a sigma around 1.0 should work well enough in cases where there aren't large flatish areas.

As pointed out, the issue is your original heightfield.

It only has 29 levels of grey.
