I was long in doubt about what I was going to do for this round of the 
TC-RTC. Finally, I opted for revisiting an older scene from 2005/2006, 
with major changes, not the least by rewriting the scene to version 3.7.

So not entirely original and yet new. I hope you like it.

Looks good. However, bottom half doesn't look as realistic as the top half. Not
quite sure why. Maybe add more foliage?

eg Jaime's amazonas

I agree with you about the foreground. Imo, mainly due to the slope 
angle test for vegetation. I consider adding loose rocks in that area. 
Probably the isosurface too looks more artificial in close up but there 
is not much I can do about that...

However, the scene should /not/ look like Jaime's Amazonas ;-) It is 
/not/ a jungle environment.

Hi Thomas,

A great image, the rock face looks good, I think maybe the contours/edges of the
ground are a bit too sharp. The image reminds me of some of gerberc's works
which I always loved.

Good work, I like the waterfall. A great landscape.

Yes, gerberc comes to mind indeed now that you mention it. I also loved 
his work.

I agree about the contours and am not sure how to amend that. I probably 
would need to add a function to make it more random at the edges while 
the flats remain... flat.

I worked on the function to get it a bit rougher and made a couple of 
other improvements. I increased the vegetation to 70k trees (was 50k) 
and restricted the 'grass' a bit more spatially. Still, 200k of those 
planted, which was a bit backbreaking indeed ;-) This should be it.

Or perhaps it is because of the probably not much modified ridged 
multifractal function for the foothills' isosurface! That looks somewhat 
artificial, not like a natural terrain relief...

This is a problem which also occupied me during my (someday to be 
resumed) Ghurghusht project in 2010 - how do I get a realistic 
small-to-intermediate scale valley network based on isosurfaces? And how 
may I integrate these valley network structures into a global-scale 
isosurface relief of an entire planet?

You may have seen now my second final. I indeed tweaked the parameters 
of the f_ridged_mf function used for the foothills to get a more 
natural-looking terrain. However, I had to be careful, in particular 
with H, because when too close to 0.0 it broke down the trace() function 
for the vegetation. A assume a max_gradient issue but I am not sure. 
Anyway, I am satisfied with the latest render.
