message: Speaking of fractal landscapes... the bit about erosion is not entirely correct. There is fractal rivers by prof. Bardeen (avaliable in MojoWorld) that focuses on rivers, and "fractal erosion" by myself ( http://dmytry.pandromeda.com/mojoworld/erosion_fractal/home.html ) that focuses on weathering (& can do some rivers). Though I worry that it would be considered "inapporiate advertising" if I correct this page regarding the erosion effects. It would link to pandromeda too much, or allright? I need input from somebody who are "neutral", i.e. aren't "attached" to any fractal terrain rendering or generation software.
:Seems more than relevant to me. I for one am interested... Go ahead  -Averisk
:I would be very interested in seeing some details of how the fractal erosion algorithm works.
This page does seem a bit Mojo-centric. How about some mention of the other very well known early (VistaPro, Scenery Animator), mid (Bryce) and contemporary (World Construction Set/Visual Nature Studio, World Builder, Vue d'Esprit) tools other than MojoWorld? -Chris Hanson, 3D Nature (makers of WCS/VNS)
Well, there are tow parts of processing a landscape:
The first part uses random and displacement. It is correct written: The generated structures are not very natural and they are not really fractal. The results are more the chaotic part of fractals.
The second part is the simulation of erosion or other landscape forming processes. The author does not seem to be up to date. Nearly every software, which deals with landscapes, also offers erosion algorithm, even Bryce.
The qualtiy of the terrains depend on the subdivision process as well as on the erosion.
Two top leading landsape generators, GeoControl and Worldmachine, offer very powerful and realistic erosions combinded with different subdivisions. Although the landscapes are still not really realistic, they are getting more close to realism with every new upgrade. - Johannes Rosenberg Developer of GeoControl
It is worth noting that above-mentioned erosion methods, that are available in nearly every landscale software, simulate the erosion on a fixed-resolution height field, and most do not scale properly to different resolution (so its really not much of fractal here). Thus these are not relevant to fractal landscape generation. - Dmytry Lavrov (developer of erosion fractal). 78.60.1.199 (talk) 20:08, 29 June 2008 (UTC)
thread_title:  Erosion 

message: "... disappointment to those who expect eroded mountains. ... many simple fractal processes do not mimic actual geological and weathering ..."
Discussion above seems to indicate that algorithms exist that are, to some extent, able to handle this. Can anyone drop me a link to such an algorithm, preferrably with an accessible explanation? It would be intersting, even though, or perhaps because, I haven't really done any landscaping. Shinobu 05:50, 9 December 2006 (UTC)
