Random midpoint displacement method

This method seems to be also documented here:

http://www.cescg.org/CESCG97/marak/node3.html

and in the paper by

Fournier,A., Fussel,D., and Carpenter,L. 1982. Computer Rendering of Stochastic Models. Communications of the ACM, 25:371-384

Journal Article Reference

I believe that there is a journal article on the method described on this page. The algorithm described here appears to be one of the algorithms discussed by Gavin S.P. Miller. Here is a reference to the original paper (also given in the web-links):

Miller, G.S.P. 1986. The Definition and Rendering of Terrain Maps. SIGGRAPH '86: Proceedings of the 13th annual conference on Computer graphics and interactive techniques, Dallas, August 18-22. Volume 20(4): 39-48.

Could someone either create a new page based on the square-square algorithm?

Then, perhaps someone could add in the details of the diamond-square algorithm. References are given in the paper above.

Completely Wrong

This leaves out the diamond in the diamond-square algorithm. :| —Preceding unsigned comment added by 24.176.245.100 (talk) 01:29, 15 June 2008 (UTC)[reply]

Yeah - the algorithm described is not the diamond-square algorithm at all. The first external link is the only useful thing on the page. 70.232.164.111 (talk) 06:54, 19 June 2008 (UTC)[reply]

I agree, I find that the algorithm is not the same as described. This is more like a 3d version of midpoint-displacement algorithm. Anyone want to move this algorithm and examples to that article instead? Paxinum (talk) 09:45, 19 February 2009 (UTC)[reply]

Redirect

Hi! Can someon please take a look at this page, and maybe redirect things like "Plasma fractal" to here? I'm still new to the wiki system, but Im learning. If there is a need for more images, I have software that can generate such. Paxinum 13:34, 3 April 2007 (UTC)[reply]

Diamond-square and plasma

The article don't point out a little difference between the diamond-square algorithm and the plasma algorithm. The latter is the algorithm described in this article, while the former compute the midpoints of the sides as average on the "diamond", as described in Diamond squares algorithm (that should be merged or split) and in this reference from the article. --Banus 18:12, 24 September 2007 (UTC)[reply]

Split the article?

It appears that this article covers two separate algorithms: The random midpoint displacement fractal (a.k.a. plasma fractal), and the diamond-square algorithm (a slight modification to the algorithm).

I would recommend one of two courses of action:

Split the article into a new one called Random midpoint displacement fractal. Most of the content should move there, and only the part about the diamond-square algorithm stays here. Or,
Rename the article to Random midpoint displacement fractal, and keep the content the same. Because the diamond-square algorithm is just an extension to the much more widely used random midpoint displacement fractal. This is like having an article about tea that is called "sugar cube" because it notes at the end that sugar cubes may be added to tea.

In either case, Plasma fractal should now redirect to Random midpoint displacement fractal since those two terms are synonymous.

I'd probably rather do the rename, actually. There isn't really enough content for two articles. —MattGiuca (talk) 06:18, 3 November 2011 (UTC)[reply]

Animation of the iterations?

I think it would help get the idea across better if there was an animation showing the algorithm progressing thru it's iterations. Could someone make one like that please? --TiagoTiago (talk) 10:49, 20 December 2014 (UTC)[reply]
