Examples of using the Erosion Operator

Perlin / Difference (Erosion Field)

Some very interesting looking possibilities here. Looking forward to your additional work here.

Billowy Perlin / Difference (Erosion Field)

These are interesting exercises. I have not had this kind if effect using this. Nice work.

Rigid Perlin / Difference (Erosion Field)

[Henry Blewer]

All these are on the flat default terrain. It would be more fun perhaps to try this on various slope structures. Still, the effects on the plane are quite cool looking. Are you using a node group to influence the way the erosion occurs?

The Difference (Erosion Field) is what flattens the terrain. I am not using a node group for the influence of the erosion. Eroded Heightfield will be next after Difference (Erosion Field).

Perlin / Erosion (Eroded Heightfield)

I do not have enough time to finish the rest so if anyone wants to continue to explore the Heightfield Erosion Operators, then by all means please do. Here are the files.

Lastly i leave off an example of three different types of combined GeoControl 2 erosion applied to a Rigid Perlin fractal from Terragen 2 with no fractal details added.

Hmmmm... i somehow get the impression that this is not important at all.

[Seth]

it is important and we don't see a lot of erosion comparaison jobs in here ^^

[cyphyr]

Oh yes it is

I think everyone is always busy researching their own projects. I know I am; but seeing stuff like this is very useful. In time to come I'll remember some thing from a past post like this and find its exactly what I was looking for for my current project.

The last image looks particularly usefull. Looks like rivers to me Your using hight fields as your basis, something I almost never do, but I can see the value of working this way.

Keep it up

Alright, so i gather that you all are aware of the importance behind the realism as i now figured so i will honestly say i am encouraged to try my best to finish the tests. I'd do fully completed projects myself, however i have a very old PC and that in effect makes things hard to complete no matter what i am doing but i can do these tests.

The last image with the GeoControl erosion is a thin flows sediment i think. It cuts fluvial channels in a very realistic manner.

I think i will try and see if there is a way to use the Terragen Erosion Operations and see if it may be possible to get the deep cut channels as well without having to export the height field itself. The Alpine Fractal may be of some use as well.

yes please, continue your research, and sorry if you felt a bit alone with us reading and not responding ^^
cheers !

No worries.
