Still with ample room for (technical) improvements, and as yet only the 
start of the intended scene.

- The landscape is - as usual - made with GeoControl. As I try to 
improve my use of programs from scene to scene (who doesn't?) I opted 
here for as large a terrain size as possible (4096x4096) in order to 
increase the level of details, the scene itself taking only a small part 
of the whole.

- The river water was what the discussion in p.general was about a few 
days ago. The surface consist of a height_field based on a grey-scale 
stream pattern image_map created in GIMP over an orthographic view of 
the landscape. The 'foam' on the water was the feature giving me 
problems initially [for completeness sake: 
http://news.povray.org/povray.general/thread/%3C5b0d3e84%241%40news.povray.org%3E/ 
]. It's image_pattern, also a grey-scale image, was also drawn in the 
same way but its use inside a texture { } needed some transformations. 
The result is pretty good, especially in the background where rapids are 
suggested. The foreground is less convincing and I reduced the foam 
accordingly. Overall, the tweaking of the different texture settings 
took most of the time.

- The rock fall at the base of the cliffs is composed of a randomly 
transformed mesh object, altitude- and slope-controlled. In particular, 
the rocks become bigger higher on the slopes, as also - in about 20 
percent of the cases - below the water surface.

- The clouds are based on a df3 object (thanks to Gilles Tran).

And now, back to the drawing board!

Beautiful landscape!

Being on my side of the Atlantic, when I saw the subject line, I half 
expected a rendering of a huge wall and immigration police rounding 
people up.

You are not wrong, but... ;-)

It is too mountainous for the Irish border. Unless it is metaphorical.

The striations on either side of the valley look different. Is that a 
hint to scale?

Only partly so. Just wait and see ;-)

They are two different things and both are present on both sides, only 
in the shadows the finer striation is less pronounced. The colour 
banding can be seen as changes of sediment composition over time; the 
finer, tabular, striations represent the lithification process of the 
sequence, also over time but on an even larger time scale than the former.

As this last striation is a normal, it is less visible in the shadows, 
although normal is 'on' in the radiosity block.

That's what I thought I was seeing but explained well.
I like the effect as I said. It gives a sense of scale.

I am running three slightly different landscapes in parallel. Here is 
the third variation which probably will become the principal one. I also 
tweaked the rocks and the foam.
