Waterfall once more

[Dune]

Iteration 1.

Detailed view.

I like it! Especially the second one Ulco

These are really good. I am curious about the top of the falls. Is this an object warped to make the 'bend' from level water to the cataract?

[sjefen]

Very cool work 

[Dune]

The water is based on a soft edged and warped circle (get position+add vector for the location, and a smooth step with its inner and outer size). The rivers and lake are based on a simple image map (I used SSS's before, but this was simpler), the rest of the countryside is blended inversely by the image map. The water is put in only in horizontal areas, the foam is just a Y stretched PF on a separate surface shader. The low area foam and mist is blended by a soft SSS around the lake.

Brilliant

I'll have to try this. Thanks for the explaination.

LIke image two the best!

Ulco, squint and you can see that river flowing!
Real soon, for real, I hope ;

[jamfull]

Awesome! I had a go at this recently too. It looks like we had similar ideas. Excellent work Dune!

Another version where the soft circle is displaced down into a crevice.

[Seth]

SSS ?

[Henry Blewer]

Really a great job. Have you tried to get the falls to 'bend' around outcrops?

[Jo Kariboo]

Impressionnant with good result !

@ Seth:

The water is based on a soft edged and warped circle (get position+add vector for the location, and a smooth step with its inner and outer size).

So not an SSS.

These latest are based on a set of image maps, which I found much easier to handle than randomly warped procedural means. Three maps: water, crevice and one to add the mist and foam at the bottom of the falls. One tree and two shrub, of which I forgot to plant one on the planet (or: the elephants are thrashing them around).

Bending around outcrops, mmm.... hard I think, very hard.
