There are some Terragen export plugins (SOPack) for POV-Ray HFs, BMPS, ect,
but I'm not sure about the 16 bit aspect.

Yes, today my brother wrote two utilities - one converts the 32-bit
float format from WM to 16-bit raw integer (that PhotoShop can read),
and the other converts from that to PNG. He's merging them into one at
the moment, cleaning up and adding a more user-friendly set of
command-line switches. Expect the source really soon, and if we can
get our hands on Borland C++ 5.5, a Windows binary (you can always
build your own Linux one if you want to).
The utilities work and I'm already using them :)

Is there anything he can't do? ;) Tell him he rocks and that we'd like to
see the source soon. :)

Great! Well, I already use a converter suggested by the creator of WM.. It's
a less elegant choice but until your utilities are ready it will do fine.
1) Output from WM to Terragen file.
2) Load into Wilbur. Expand range of values 0 to 1 into 0 - 65535
3) Output as 16bit POV-TGA
Wilbur can be downloaded here:

By the way,
If someone thinks it could be useful to have the same color maps in POV-Ray
as those used in WorldMachine previews, I wrote a converter. It simply read
the color maps into POV pigments.

Sure thing, if I get to see him soon - he went out for a football
game. Meanwhile, I took over merging the (now) 3 programs into one (3
because he decided he didn't like the command line lib in glibc [or
gcc?] and wrote his own one). That is, when I'm taking a rest from the
Flayer Dungeon on Hell :)
Don't worry, I won't have much time to screw things up - he'll be back
early tomorrow (if 2 am counts).

I couldnt find any referance to expanding the range of values...
Could you tell me how it is done? Please? Thanks.

Hmm, you have downloaded Wilbur, I suppose? I found out, that simply loading
and exporting the file won't give you a nice 16bit image for POV.. I guessed
that expanding the values would solve the problem, and it did.. Here's how
to do it:
Load the file.
Go to menu: Surface / Point Process / Scale
In the popup window, select scaling type: To Range
Enter the values 65535 as "Highest" and 0 as "Lowest"
Click Ok.
Save the file as "POV Targa surface 16bit".
And by the way, there won't be any visible change of the image in Wilbur,
after you scaled it. But there will be a big difference in POV! ;o)

Hugo

I have had Wilber arround for a few years. I got the
newest version about 2 months ago.
