Splendid vista! Great work on erosion!

Fantastic, Dmytry... can you soften a bit this effect and mix it with non-eroded parts ? Very promising plugin...

Cool colors too:)

I think your Mojo developments here will prove to be even more impressive than the Volumetrics. I had a look at your website. The picture showing the mid scale erosion looks very impressive. Can the erosion be applied to individual terrain fractals? Many landscapes are made up of components which erode differently. You may have hard rock outcrops where not so much erosion has taken place. The structure of the rock defines the erosion more. Presently this part of Mojo can be faily realistic. Then there could be lower altitude erosion deposits which get eroded further into channels similar to your erosion examples. This is where Mojo is currently weak because lower level land is often composed of material which erodes easily with water and moves very easily simply with gravity. I think this image by Olivier is an excellent example of the kind of erosion we dream of having in Mojo. Maybe your erosion fractal can create similar results but of course with endless procedural detail. It looks like there is a heavy amount of both erosion and deposition going on here: http://www.renderosity.com/viewed.ez?galleryid=1031194&Start=37&Artist=hillrunner&ByArtist=Yes

Yes, erosion is fairy controllable; i'm is working on some implementation things now, but it will be surely possible to specify what erodes more and what erodes less. The rocks that don't erode much will still affect flow. And yes, my erosion does deposition too. Speaking of realistic erosion, I quite recommend doing google image search for "mountains", or zooming at any mounains in google earth. Real mountains are very heavily eroded (more than low terrain, or so it seems). Actually i haven't yet seen world machine erosion that looks much like real mountains... i don't doubt it can be done, just i wouldn't base the impression of realism on some application and would rather look at real world images...

For example of what I mean, http://maps.google.com/maps?f=q&sll=36.031332,-111.445312&sspn=8.293855,14.941406&ll=40.741014,-110.505981&spn=0.485908,0.933838&t=k I just zoomed in at 'random mountain'. You can look at other, more geologically recent ones, them is very eroded too. It's something that WM users seems not to do often - it's millions years of erosion at work and that would take long for computer to simulate in WM way. I.e. I just would prefer & recommend comparisons with real world terrain. (I think with certain settings my erosion will be able to simulate WMs erosion, but are not very interested in doing it myself.)

Amazing! :)

Looks great! You're really on to something here! I agree with you that the visual end result is more important then calculating a whole real world erosion simulation over millions of years. In 3d land the quickest best looking end result often matters more then the physical accuracy compared to the real world. I've always considered aesthetics to be more important then realism. Along that same line of thoughts I would be very interested to know if it will be possible to apply the fractal exclusively to seperate elements of mojo terrains? And if it's possible to control the intensity and other such variables to your erosion fractal with other mojoworld controls? (fractals, altitude, slope of the terrain that the erosion gets applied to, etc. etc.) I'm also wondering if this fractal allows you to set up different base functions, like in the mojo fractals I'm used to from MW2.. (voronoi, perlin, etc.) If so, this could allow for interesting variations in various shapes of the erosions.

really impressive - please keep developing it

Amazing stuff! Can't wait for this :)
