Title: River
Post by: Dune on February 02, 2016, 11:36:36 AM
I had this idea to make a sunset kind of river scene, so here you are (WIP). In the distance the low marshy lands end into a row of dunes before the river flows into sea. The Roman border road lies alongside the river, a watchtower every few hundred meters (edited pop). Maybe I'll add a boat or two, a castellum, and change the vegetation. The encircled river area lacks depth, and I have to set that right, as I want a continuous glowing river.
This (detail 0.6, AA 6, soft shadows, masked out water areas) took 1hour and 17mins on an i7.

Stunning view and work on perspective is really nice :)
Actually, it's all good looking and the composition really leads the eye, I like that.
The road is distractingly wide and "dominant" though?
Title: Re: River
Post by: mhaze on February 02, 2016, 05:14:47 PM
Great POV and the atmosphere is wonderful.  I agree with TU about the road but I suppose you have little choice but to include it.  Perhaps it could be partially hidden by vegetation and trees?  I like the river banks and the ponds but the trees seem too sparse, though I like the long shadows they cast.

Quite a good impression of distance and scale. The atmospherics look well lit and convincingly heavy. The smaller ponds are neat to see as well. Like the upper Canadian Tundra and Taiga. The roads do seem to stand out in certain ways but as was mentioned it might be necessary the way it is.
Title: Re: River
Post by: Dune on February 03, 2016, 02:50:26 AM
Thanks guys. I really don't know how the Romans kept their roads, but I guess they were pretty good at it, this being their main military artery on the northern border of the empire. Should be 7m wide, which it is. But I agree it stands out. Too much vegetation would have been cut down, as the watchtowers should be in sightlines.
I think I will add more trees in the marshy areas away from the river, and improve the castellum. And I don't like the flat light on ground, perhaps more diversity in low vegetation. Will be continued.

I noticed the water shader has some ugly black patches down below. Mmmm.
Title: Re: River
Post by: AP on February 03, 2016, 03:11:16 AM
Yes, i can see adding more trees in those areas now when i look at it again and agree about the low vegetation. What about some stones for less flat ground also? Would there have been a good amount in this region?
Title: Re: River
Post by: Dune on February 03, 2016, 07:54:57 AM
No stones in that area at all. The only big stones to be found in our country are deposited here in the ice ages, and that didn't go all the way across the country.
Title: Re: River
Post by: DocCharly65 on February 03, 2016, 09:17:27 AM
Very nice project again, Ulco  :)

In the first image I didn#T like the sand banks in the river but in the second it's ok now.

Good that it seems to be just a trail. Some weeks ago I saw a documentation and learned that the romans built most of the paved streets only straight and rectangular because of their way of measurement. They couldn't build curves.

(hope the documentation didn't lie at me... )
Title: Re: River
Post by: otakar on February 03, 2016, 11:35:35 AM
The Romans did not have mowers (but again who knows, they were advanced? :) ) so at least grass and bushes on the margins should make that highway stand out a bit less. Cool view.

Post by: Dune on February 04, 2016, 02:51:08 AM
The area was largely uninhabited, 'hostile' tribes living in the northern area, 'domesticated (by the Romans) tribes and Romans in the south, the Romans principally in castella and larger 'towns'. The rivers found their way through marshy, boggy low land, and deposited sandy banks. Off those banks it was very wet and boggy. Later these extensive bogs were cultivated, excavated for peat and dried down, so nowadays the rivers mostly lie higher than surrounding countryside, hence the need for Dutch dikes. The Roman border road and castella were built on the river dunes area.
So this morning I had this better idea to first raise an area of wide sandy deposits, use the inversed mask for the bogs, then make a shallower line for the river and smooth that down again (partly). I also want to make more dunelike areas.
Still no need for a compute terrain  ;)

The areas between the towers would have been cut low, but for the rest there may have been large extents of 'wet trees' and shrub.

Some next WIP's, still no good at all.

Title: Re: River
Post by: Dune on February 04, 2016, 08:16:21 AM
Thanks, Mick.
I've made a completely new setup this morning, building up as described, which of course became more complicated while working all masks out. Now the vegetation in the dunes can be adjusted to fill valleys, water level, waves and coloring can change between river and marshes, dunes can be raised or lowered, etc. I am curious to see if I can make a braided river out of this, or at least some parts to braid in and out.
Another light direction is now rendering. Still no compute terrain, so rather fast (39mins at detail 0.6 and AA6).

And other light.

Title: Re: River

Right, I don't use slope restrictions, just heights, so I leave the compute out. That's the benefit of a flat country  ;)
Getting there... but there's a mistake in here (in masking)  :(   And the trees will be much better, just finishing some new willows. Shores haven't been done either.

Post by: AndyWelder on February 04, 2016, 12:51:04 PM
Well, no real input on this so familiar landscape from me, just that I'm in awe. These scenes are beautiful, Ulco. Oh and about the Roman roads: Didn't they use so called "knuppelwegen" (stickroads?) in the marsh areas?
Title: Re: River
Post by: otakar on February 04, 2016, 06:19:40 PM
Ulco, looking real nice, but this piqued my interest in Roman roads again. They strived for straight lines, going as far as diverting streams and draining marshes and of coure building bridges. Not sure if they would follow large rivers, in particular in the provinces, could not find any definite pointers towards that in my google session. But I found this Dutch project, which is quite interesting. http://mappingtheviaappia.nl/project/

The Via Appia itself had a perfectly straight 90km long section. Incredible feat!
Title: Re: River
Post by: Dune on February 05, 2016, 02:42:26 AM
Thanks for thinking along, guys. Your thoughts made me think again and send some emails. I have to know for sure (if they know) if the northern military roads were also straight. Technically, I hope not, as procedurally it's much more cumbersome to implement, if not impossible. Interesting site, btw, thanks for the link.
@Andy; yes, they made 'knuppelwegen' through marshes... nice idea for another impression one day. Thanks for bringing it up.
Title: Re: River
Post by: DocCharly65 on February 05, 2016, 04:44:43 AM
The POV looks much better now with the river from bottom left to upper right!
I love that wide view!

...and good to know that I was not dreaming with the straight streets.
I read ome more details: The romans led their "via strata" even straight through swamps using dams. and they didn't pave their roads continuous, but only before crossings, towns and in difficult terrain.

I abandoned the previous setup for a new one (having learned one or two things), where I tried to get the river to 'erode' and 'deposit' in a more natural way. Base needs some work, as the far river is drained by too large X to scalar northern hemisphere morenes.
Title: Re: River
Post by: AP on February 11, 2016, 02:47:03 AM
That is a good more realistic river concerning the shore morphology.
Title: Re: River
Post by: AndyWelder on February 11, 2016, 08:46:12 AM
I wonder how you manage to fit the water object into the bed over such a large distance; if I try this the river disappears and leaves a dry bed or it spills over the bed and floods the land. But I figure from the
Quotefar river is drained by too large X to scalar
part there are blue nodes  :o involved.
Title: Re: River

Title: Re: River
Post by: Dune on February 11, 2016, 10:24:39 AM
You have to use simple shapes that overlap eachother, the river area (banks and such) being a wider SSS than the river itself. Then warp both, and if needed transform each warped SSS (move or stretch, or whatever) or warp again to make a difference between the total river area and the river itself. The blue nodes I mention were for the high northern land, but I dropped that and used a huge oval SSS as well, worked better.

River area is claylike, so no bright yellow-white dunes any longer. High ground on right is poor heath, and grass. Southern part, beyond river is wet and boggy.
Title: Re: River
Post by: DocCharly65 on February 11, 2016, 10:59:29 AM
I like this new river bed very much!

It's very interesting to follow the project growing or changing.

It would be interesting to see somthing complicated like the river bed as a "SSS tutorial"... untill now I just tried easy and really simple shape shaders like rectangular and combinations of rectengulars in my "SilentHill street" . did I miss an interesting post somewhere?

@Kadri; I learned from a few archeaologists that river areas and beyond were different in terms of soil and layout, and vegetation. So it wasn't really correct in that sense.

Title: Re: River
Post by: Dune on February 12, 2016, 03:32:34 AM
@Nils: probably; I've posted a basic river setup a year ago or something, but basically it's simple; use a warp shader with the SSS as input and a vector displacement as function and feed a PF into the function input of the vdisp shader. For warp in X direction, set the scale of X a bit bigger for more even width of the river, I usually set Y scale at 1000, just to be sure the fractal doesn't change over height (especially for roads). Vdisp shader X at 1, rest at 0, offset of X at -0.5, so the basic line stays centered. And then you can play with PF settings, and add all sorts of variations (extra PF+vdisp). You can even (don't tell anyone  ;) ) use this as a mask for a surface shader, give a nice white color and use the breakup for some nice effects (breaking op the [grey] sides of the warped soft SSS). It's a huge playground  ;D

Title: Re: River
Post by: Dune on February 14, 2016, 06:50:40 AM
In fact it was rendered bigger (3000px wide) with soft shadows on at detail 0.8 and AA8, but reduced using Irfanview and sharpening. Not the perfect degradation of course. And, btw, didn't use a compute terrain here either, so it was a relatively fast one at 2hours. Here's a part at 100%.
Title: Re: River

Forgive me for inquiring just in-case this was asked by other people but how can you get away without using a Compute terrain shader?

Well, guess I learn something new everyday.  Somewhere I got the idea in my head that my image size could not be larger than my monitor size (1920 x1080).  But when I rendered larger (3000x1687 p) and saved to hard drive, the properties file did indeed indicate the render was 3000 x 1687.  Thanks Dune!!

@ Andy and Richard; yes, to discourage misuse. Always a bit paranoid, though I like to show stuff and encourage other TG users, I can't often post large finished (commercial) images, at least not without any form of 'disfiguration'.
@ Bobby; yes, I think I've tried almost every node and combination, but the stroke is too hard for a moat. I do have a setup with 2 SSS and some subtraction, but the corners are always a bit too sharp. So in this case I have simply painted a simple grey mask in PS, set it at 0/0/0, and located/rotated that on 2 locations through 2 transform shaders.
This render will be blown up to 80cm wide and framed as a farewell gift for an archeaologist, so, though I started it as a private thing,  I didn't make it for nothing.

This render will be blown up to 80cm wide and framed as a farewell gift for an archeaologist, so, though I started it as a private thing,  I didn't make it for nothing.

Nice the way that worked out...but art is never for nothing though. Yeah I thought you may have...it's sharpness and undisplaceableness (izzat a word?)make it mostly not that useful. I like your more portable solution.
