Help with terrain maps
Hi all,
I've got a problem with getting some terrain-map i created in Bryce, into a 3D game. As you can see in the picture below, you can see in the center part my height in the terrain map is terraced, i mean, it has a certain great value, and then it suddenly changes to a next value. I'd like to smooth that out. I've been playing around in Gimp & Photoshop, but i can get it smoothed. Given the amount of talent that visits here, i thought i might well ask for help here.
thanks

Personally, I never had any luck blurring something like this...it just extends the terrace outward. I never tried 16 bit mode though.

Working with a jpeg leaves something to be desired....
but I pulled it into wilbur, selected the lowlands with the magic wand, then ran the deterrace filter, added 1% noise then deterraced again.
Here is the 16 bit png.
(also zipped, as I'm not sure if the forum supports 16 bit)

Badger,
Did you mess with Image->Adjustments->Levels in PS?
Thanks a lot for the advice.
The heightmap was actually created in Bryce & exported to a jpg file. As RobA suggested, i'll try an export to bmp, might yield better result.
Will try it later tonight.

@badger - You won't get any smoother using any 8 bit greyscale. The terracing is just due to being limited to 256 levels of grey.

i see, yet the current image doesn't use the full range of grays.
I might get this to work by adjusting the levels, so the entire range from pure black to pure white gets uses. Any pointers on smoothing the histogram when i do that?
thanks

OK. Here is the 8 bit deterraced png from wilbur. This should be stretched the whole range.Originally Posted by Badger
