Geofiction Base Maps using Wilbur

[waldronate]

So a quad core processor with 12+gig of memory and a 64 bit version of windows 7 could take the software to its logical limits?

I was thinking a dual quad with 48GB myself but only because I can't justify the $40K for the quad socket quad core with 144GB...

Here is what a couple more incised flows did applied at different settings to 3 different elevation groups. I think it gives a better feel for this scale and I am happy with it for the purpose. Most of all what i'm looking for is relative consistency from map to map that will stand up at a wider scale (continental) so it wouldn't be in my best interests to start making the landscapes too unique. And I suppose that is where the "fiction" in geofiction comes in! Unique natural featurs that could plausibly fit into this overall landscape don't necessarily have to be featured on the map in perfect topographical scale as much as i would love that.

Maybe someday Wilbur and Fractal Terrains will have a baby (-:

.... one question i do have that i couldn't find a satisfactory answer to:
I have been outputting gray-scale image from FT to open in wilbur.. works fine... BUT, I would like to have wilbur know where sea level is automatically instead of having to mess with the scale or range which wilbur doesn't remember the next time you open the file. I would simply make my color scheme in FT conform to this... output... input to wilbur and boom.. perfect sea level.
How do i do this? Seems like it should be obvious like (ie) "set sea level : RGB value" or something.
It doesn't make sense to have black as the default sea level when you have negative elevations (depths).

First point. Images don't contain real elevation data, just numbers fro 0 to 255(0 to 65,536 for 16-bit), so you have to use the Mathematical>Span filter to tell Wilbur what span of heights the image represents. You can find a tutorial here to tell you how to save the data in a full precision binary format. You really want to avoid greyscale image files for elevation as much as possible.

Second point. You are now required to put up a tutorial on exactly how you did this:

I think you might be using something similar to what Mr. Slayton does here, but if you've come up with something that works better for small scale(large area) terrain, then me wantee!

I sure hope not because Wilbur gave birth to FT 0.0 12 years ago...

In FT's File>>Save As menu there is a file type called "Wilbur MDR Files (*.mdr)" that outputs the current view as an MDR file. I recommend this file type for use with Wilbur. I also recommend http://www.ridgenet.net/~jslayton/Th...ain/index.html as a tutorial for using Wilbur together with FT.

UGH.. well that would be incest then, huh? hah.. then why can't you use wilbur like a sphere and erode the whole dang planet... or can you and i'm just ignorant... which i am since i'm a wilbur newbie.

Thanks for that .mdr advice.. i had no idea. AND that link to 'there and back again.' I have randomly found some of his pages via the wilbur page and google search. If you know of a better index of his tutorials other than what is at http://www.ridgenet.net/~jslayton/wilbur.html i'd love to find it.

Although i am bit confuse about this tutorial here http://www.ridgenet.net/~jslayton/Fu...ol5/index.html I can see he's going from wilbur to photoshop and i think i get the concept but am losing him at the last 2 pics.. he says he's applying more erosion so it has to be in wilbur.. then is he again going back to photoshop and compositing it for us to view? To a newcomer it almost makes it look like it's all being done in wilbur (the 'refilling' of the lakes) but in reality i think most of it is just masking in photoshop using the outline of select basins. Am i right here?

Well, i've got a lot of experimenting to do. Thanks for the help, i'll try to be more resourceful digging up info before asking.


and yes su_liam, i did use that tutorial you linked to.. i did a different setting for each of the low, med and highest terrains.. then went back one more time overall to finish it off nicely. I have i all written down so i will most definitely do a tutorial on how i get my final satisfactory results when i get to that point.

Thanks again.
