what is this type of surface/geometry called?

maybe a kind of minimal surface?

certainly a folded surface!

Hi Michael,

I think RWNB is right.

It seems like it is a kind of Schoen Surface (minimal surface).

Maybe this link is useful to answer your question.

Best,
Martin.

The guy's name is in the corner of the image - it took a few seconds to search that and find the page with more info on the project : http://www.oliverdibrova.com/blg/?p=283

So something to do with the 2D patterns formed by sand on vibrating plates.

It isn't really clear from the page how he uses that to go vertical, but perhaps stacked and then smoothed in some way.

So I wouldn't say this is a type of surface as such, though they do bear some resemblance to some minimal* surfaces, or Riemann surfaces, or to rheotomic surfaces

*I'm pretty sure they are not actually minimal surfaces, as I think I can see some regions of positive Gaussian curvature

Sometimes it is better to have a closer look to the corners of the image. ^^""

Also, as Taz pointed out the other day - even if the image doesn't have a name on it there is reverse image search :

Nice. :)

I think I missed this somehow.

i think: "how he uses that to go vertical" is the main question!

and this would only be attractive, if his approach would be parametric.

maybe that's the question, for which Michael is interested? :-)

there is one way!

i know where the project is from and i know the min surface link. i have the project posted on my site. just wondered if the surface had a specific name/creation method. thanks guys. also on google in images you can just drag the picture onto the search bar as well. and tganks for the links Daniel, interesting stuff.
