Thanks for the lite challenge vote.

Hey, I see that you've done some plate tectonics based mapping. I'm looking to get into that, but am having a hard time figuring out (a) what software works for that, and (b) how to generate a starting set of plates. Do you have any suggestions??


Thanks in advance!!

Thanks for the rep on my "Ghastly Rest" map - much appreciated

Waldronate, I'm hoping you can help me, since you are also a cc3+ user. Could you visit my Aeterna thread in the world/regional WIP category? I could use your expertise...

Thanks for the REP

Cheers for the vote in the Lite Challenge waldronate!

You have a really wonderful sense of humor. I'm quite enjoying your comments.

To get a cylindrical noise field in Wilbur, use Filter>>Calculate Height Field. Select Type=Math Function and enter "ridged(1*cos(2*pi*ix/ixsize),1*sin(2*pi*ix/ixsize),4*iy/iysize)" as the expression. The 1* terms are the radius of the cylinder in noise space (larger values will get smaller noise) and the 4* term is the height of the cylinder in noise space. "ridged(x,y,z)" is the ridged fractal noise function ( "fbm(x,y,z)" is the fractional brownian motion function ). The "ix/ixsize" term computes a function from 0 to 1 horizontally in the image; the "iy/iysize" term computes a function from 0 to 1 vertically in the image. 2*pi*t converts a number from 0 to 1 into one ranging from o to two*pi (in other words, an angle). The cos(t),sin(t) item computes x and y from an angle t.

Hello,

I was just wondering if Wilbur is able to do a cylindrical evaluation of a height field. If this is the wrong place to ask this question then I apologise.

thanks for the vote W
