Hiho,

what about a gallery or a gallery thread. Although I guess that it will cause some support work on how to add images to a posting. Having said so ...

... I hope I succeed:
Blech, Messing & Glas

That's some gyroide rendering fun =)

That's part of a little silly Flickr stream: http://www.flickr.com/photos/schmiegl/

Hi all,
Very beautiful images and I specially like the mixture of textures Smile

The idea of a Gallery is very good and I will think about it.
Also you have a very interesting gallery (not "silly" at all) Very Happy . Keep up the good work.

Thank you!

that looks good! For now I plan to feed this thread when I have new pics, and I hope to get some new people make stuff too ...
I'm - still addicted to the gyroide ... what a wonderful shape!

Thanks again for opening the door to me for this object!

Cheers,
Florian

I tried to do an image showing the famous voronoi subdivision of a surface. I found infos on the web telling how to do that using Meshlab. It's a bit painful to get started ...

It's all gyroide here - you'll get lace thing (non laced) this way:
-((cos(x)*sin(y)+cos(y)*sin(z)+cos(z)*sin(x)))+0.026 * (x^2+y^2+z^2)
x,y,z € [-10,10]

Merci Taha,

as it turns out now that I'm not really the guy to discover intriguing new surfaces .. hope you don't mind me posting older renders - yet again a gyroide.

It's a stacking of various modifications of a Gyroide according:
f := Gyroide as in the K3DSurf samples
-f^2+c
f^2-c
(f^2-c1)^2-c2

Cheerio!

we also can cut out a torus off a gyroide volume Very Happy

Gyros Toruide ;o)


Howto (interpretation from non-pro for non-pro):
1.) If(Torus Inside,Gyroide^2-0.05,Torus Outside)
and
2.) If(Torus Inside,Gyroide,Torus Outside)

Line 1 reads as a formula:
if((sqrt(x^2+y^2)-4)^2 + z^2 < 3,
(cos(2*x) * sin(2*y) + cos(2*y) * sin(2*z) + cos(2*z) * sin(2*x))^2 - 0.05,
(sqrt(x^2+y^2)-4)^2 + z^2 > 3)

Note on Gyroide:
Default is
cos(x) * ...
I compressed it in space by factor n using
cos(n*x) * ....

n = 2

Hi all,
Very nice work Schmigel (as always).
I moved your thread here because I think it's the right place for it (if you disagree with that I still have enough power to get it back Very Happy ).
I took a look on your Flicker gallery and your printed models are awesome, I only wish they were a golden made one's (to not worry about strength/longevity Razz)
Happy new year.

Thank you Taha,

I'm happy that I was able to afford plastic made ones, in gold the would remain a dream!

However if they'd turn to gold now ... Wink

I hope to be able to promote k3DSurf and this forum a bit on Flickr as this forum here seems to be the place on the web where a maximum of knowledge about isosurfaces and parametric surfaces meets art (especially via K3DSurf as a tool and you, inode, Sjo, and Jotero/Torolf as artists and teachers (order of mention does not mean anything!)) and the most important thing, where an entry to that matter can be found for non-professionals. There are a bunch of promising talents around on Flickr - they just need be set on fire!

Gyroid made from onion like layers




I got the thing by using a sphere as if-condition and subtracting the layers via "a * cos(abs(x^2+y^2+z^2))" from the gyroid formula.

Thank you for the compliment!

I have a little problem. It's very hard to find interesting new shapes that haven't been explored already by just a few guys - even far beyond what I can imagine ....

One of these guys is from Hannover Wink

Not new at all with regard to the object - just let's dare some color! Smile


Texture is a simple flat projection of a fractal image.

Hiho,

now I had it printed in stainless steel by Shapeways - gorgeous to hold it in my hands Very Happy

Hi all,
That's a wonderful sculpture Very Happy

That's true and I can only imagine what should be to have a very big one where we can make a ride for a little promenade Razz
