I finally figured out how to apply the voronoi fractalized tgc against an xenodream object. (http://www.terragen.org/gallery/displayimage.php?pos=-6019)
Now I have to get better colors and surface etc - any advice much appreciated.
Your render on Ashundar is breathtaking ... I like the displacements on the tower ... You could go for some additional shader, which is broken up with a powerfractal (stretched along the Y axis), so you get some vertical colour changes.
Nice image...
How the hell you have do that ? ?...
NKAID...
Volker, thank you - I'm trying to add what will look like water or rust stains on the Y axis. Great idea - I appreciate it! Lots! Regarding the Ashundar render, it was a massive pain in the butt to render. I had to bust it up into tiny pieces to get it to render - probably due to all the reflections on the water.
Aymen, thanks - Do What? The tower is an object made with xenodream, which is a fractal program that I don't understand hardly at all. But it can make great/interesting objects. I'd love to make some kind of root system with it, tangled vines and such - someday. One artifact of the program is that as the fractal hits the boundary between "is" and "is not", it leave disjointed fragments that float in the air. But please be more clear about what you are wondering about, I'll be happy to spill the beans. The way I plugged it into the object, was 1) loaded fractal voronoi tgc. 2) Heightfield shaded plugged into input of last warp shader of fractal voronoi. 3) output fed into compute terrain and then base colors and surface shaders which were input into the object. Sadly it took me about three days of experimenting before I figured out to pump something into the input of the warp shader - (I am not very clever - I'm telling you).
I did not understand Xenodream, too ... but I gave up ... now I have to look at it again :D

thanks you have answered to my question...
NKAID...
I painted up and down - wish my house was so easy to paint. I think it helped, I'm not sure I like the color scheme. Also I added a reflective shader and it seemed to soften the stone and help make it seem more three-d. Any ideas anyone has to improve, I'd be much interested. Oh, yeah, before I forget, it was the tgc file from not to long ago that showed me how to use a mask with a warp and with a cloud. So I've been learning lots these last couple of weeks! Thanks everyone.
this one is really good...
NKAID...
What didi you do ? Is this another program? or another tgd file you downloaded?...
It really improved.
I do not know if you have used a surface shader as base for the weathered look. But you should, because you can try to enable the 'Smoothing effect' with a lower amount than 1. On terrains it smooooths away the underlying displacement (more or less). I am not sure but, if it works on objects.
Else you can use your new weathered shader to blend the displacements ... a bit. ;)
funny little app, I just downloaded the free version. I don't really understand it though...
I tried with the smoothing thing - but my eye is having a hard time deciding what is happening. I changed the colors somewhat, I went after a higher quality (.8), but started running into ray trace error issues. They went away after lowering the gi params to .5 -- I changed the sunlight direction, but it was probably better before. I also changed the pixel filter from Narrow Cubic to Mitchell-Netravali - I think it made the shadows darker, but am not sure. I increased the depth of the voronoi pattern (I think too much). I feel that I learned bundles, but am not sure that it got any better. Any ideas/advice much appreciated!!
I like the displacements in this version very, very much. No changes here for me, please ;)
'Almost' turning off the GI seems to be a bad idea for this render. There is almost no contrast to the clouds and object anymore. Maybe raising the Enviro light settings for the atmosphere can handle this.
I could not decide which render's sun position would be better, I like both.
By the way, I was looking at xenodream again .... [LECKER] :)
Volker
I like the last image. The harder shadows do not make the image too dark. Volker's right about the clouds.
xenodream and terragen.....very good idea !!!!!
you have some complex architecture examples files cheaped with the demo.
i will a good idea to try this into terragen.

be carefull with mesh export poly count. ;D
wow 8)
is this available as an object somewhere? Amazing!

we have to do a mesh export to use it in terragen.
check the help Pdf on xenodream website.
it's a little bit tricky and long process to export xenodream geometry with good result.
this software have a unique way to proceed geometry. i've never seen a software like that before. Is a kind of Apophysis (http://www.apophysis.org/) but in 3d !!!!
It is astonishing what Vogt has done with fractals at all. Too bad that the free version of xenodream only allows a basic grid of 200x200 ... so that much detail is not available for me, yet.
On the other hand, I had quite good (interesting results) when rendering the mesh only for a short time, lots of smoothin' and almost no polygon-reduction.
Still that missing details :(
yeah i m agree....
the license cost something like 100 $ or euros....santa will be here in only 4 mouth.....
one other very interressing application of this software is real 3d printing !!!!!!!!!!
http://www.shapeways.com/model/24470/gyroid.html
i m pretty sure we can do that with this software and some cleaning in a another 3d package...
out of topic : it can be cool to export a terrain geometry from terragen into .lwo, clean it in another 3d app, and print it in 3d.

yeaaaah ! I am a big fan !!!
