 |
|
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 
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)  . 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]

Hi all,
Nice shape and mesh subdivision Florian 
Thanks for sharing.

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
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 ).
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  )
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 ... 
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 |

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

Hi all,
That's a wonderful sculpture
| Quote: | | gorgeous to hold it in my hands |
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
