Testing a different way to create a rock face using only Voronoi shaders.

No, not so far. But it's something I could try to do, just to see what it results in.

Another iteration. There are some displacements going wrong center top, and there's probably too much gloss.

This reminds me of the terrain in those cartoony like games like Team Fortress, Fortnite, Paladin, and Overwatch and stuff. Looks very pleasing to the eyes.

Edit: The last preview looking directly at the stone actually reminds me of Tomb Raider I am playing currently. Climbing a lot of walls. Haha.

Thank you! I've used the merge shader and colour adust a lot. Basically, it is one Voronoi setup with several derivatives. For the rest, it is actually a lot of trial and error.

Colour Adjust Shader, Merge Shader (and it's overlay settings), and Warp Shader are serious friends in TG. Difference overlay is fun to play with when adjusting colours for merging and displacement.

I need to return to Lateral displacement again. I just get turned off by limited detail. I've been having fun with atmosphere stuff because the lack of polygons isn't as noticeable.

Thank you for the picture. How did u get the pattern that is on the first screenshot? Guess it is not a PF with voronoi noise. I tried that and nothing similar happened. Or its some blue node set up?

thanks Rene! The mysteries begin to unravel. I get started and then do not know where  to go after I reach a certain point .  We get used to a point and click option for displacement with no clue how it was made.  :)

There are several...voronoi cracks tgc floating around, here is dandel0's contribution link https://planetside.co.uk/forums/index.php/topic,8849.msg94774.html#msg94774
Title: Re: Voronoi rock
Post by: René on May 08, 2018, 08:33:51 AM
It's not the Voronoi power fractal but a blue node set-up. Like luvsmuzik said, on the forum are several examples. If you don't know blue nodes (like me), with a bit of tinkering you'll get an idea what it does.

Thx guys. I will cut up Dandelo's file I guess. This also got blue ones.  :(   
Math teachers should tell kids in school that math actually useful in 3D then I am sure more people would be interested. Nobody told me this before and of course my attention went somewhere else in school.  >:(

If you have AP's 100 functions....#17 is voronoi cracks also. You can use either side of dandel0's , just dissect at the merge, if I recall without looking. Pretty sure he labeled sizes.
Title: Re: Voronoi rock
Post by: Dune on May 08, 2018, 09:13:49 AM
Thanks René. Interestingly 'simple'. I have been working with smooth steps and variable high or low colors/scalars (instead of constant scalars), which is interesting too.

This voronoi is simply a get position in texture, a constant scalar for size, another one possibly for seed, and a voronoi diff scalar, after  that you can do whatever you like with color adjusts, warping, merging, etc.

I have, but not in this image. Merging two stretched(horizontally and vertically) Voronoi shaders give very nice results too.

How on earth did you get the merge result in your tut?  I've tried every variation I can think of and I can't even get close!

This is the Voronoi setup I used, it is quite simple. The quality is highly dependent on the underlying terrain. The terrain should not have too much roughness and definition, the less, the better.

I've gone back to some voronoi play, and tried to update one of my cliffs with the rock attempt, but I can't get the rocks to function correctly. Either too tall, or flattened and exploded/crunched rocks appear. Doesn't look too bad but definitely isn't the look I was hoping to achieve with the rock boundaries creating nice separation. Are there any special settings you do on the fake stones for them or displacement?
Title: Re: Voronoi rock
Post by: mhaze on May 14, 2018, 03:59:14 AM
The more vertical the cliff faces the better voronoi works also stretch the voronoi noise in the y axis.

For those of us who try....As you can see I can implement the clip on a cube, but again I am stumped as how to setup the base in a terrain. I have multiple shared displacement cliff or strata-voronoi mixes. I am clueless as to how to achieve the basic smooth face like many used in the NWDA Cliff contest, for example.
BTW, I have tried multiple times since downloading the clips.
Title: Re: Voronoi rock
Post by: Dune on May 18, 2018, 01:44:00 AM
You have to be careful just dropping in clips by others, as they won't always suit the terrain or other nodes you've put in before. Better dissect, and learn, then use the idea to build your own from scratch.
QuoteI am clueless as to how to achieve the basic smooth face
If you want to build from the default scene, you can increase the smallest size in the base terrain PF to start with (make it 5m or so), then you can decrease detail in the fractal warp (say 0.8-0.9). Voila, smooth mountains as a base to build upon. You want more steepness; increase variation in the pf, and increase clumping, etc.
Title: Re: Voronoi rock
Post by: René on May 18, 2018, 02:06:05 AM
I used a mask to displace (displacement offset) two terrains. After that, I added fake stones(optional) as a third terrain.
After the basic Voronoi texture there is also a warp and a number of smaller displacements for more variety, texture and colour.

It is a good idea not to make the terrain too detailed, otherwise the textures will go haywire.

Very good, I'd say. I notice you work on a very large scale, stones of 222m, whereas you get the impression of a scene of max ~50m diameter or so in this case. Do you decrease total size at the end or are the veggies also enlarged?
Title: Re: Voronoi rock

@Rene Thank you very much for those image examples and explanations! I was ready to just stack cubes everywhere.  :)

@Dune Yes, I had three file shares open, going back and forth, comparing. Your files usually build from a basic setup, then you add great additional features. All a learning process, but such fun! Off to experiment!  :)

The vegetation has indeed been enlarged. Occasionally during experimentation, I discover something I like, although the proportions are too large. Instead of decreasing textures and displacements, I find it easier to scale the objects down up.

Agree, have same problem at 'real world' scale hence some weirdly scaled scenes.
