"hello, at some point i gave up to region union and found a solution with clipper offset. So if using a plugin is not a problem also if you use solid union with the boundary surfaces you already have and then merge faces also gets the job done, but…"

Circular Ridge for Tubular Mesh Relaxation on Kangaroo?

Hi Guys,I started from a tube-like mesh and tried to add a ridge that would represent a kind of plastic hoop stopping the nylon to fully minimise itself (picture below). I've tried the following things (after watching this tutorial from Daniel Piker on ridges):To add anchors with a lesser  strength where the hoops…See More

Daniel Piker replied to Arthur Mamou-Mani's discussion Problems with angle force on polyline using Kangaroo 2?
"Hi Arthur, I changed a few things- Firstly, for the angle between consecutive segments, the list was shifted, but without also taking the shortest list, which caused a problem with the last item. Second - I scaled the whole thing up. To make the…"

Laurent Delrieu replied to Arthur Mamou-Mani's discussion Problems with angle force on polyline using Kangaroo 2?
"I also thought it will curl but as angles are constant and multiplied by a constant value it stays linear. It could be possible to multiply angles with progressive factor depending of the node/point number."
Nov 3, 2016
Arthur Mamou-Mani replied to Arthur Mamou-Mani's discussion Problems with angle force on polyline using Kangaroo 2?
"Thanks a lot Laurent! It works! Yeah curious strengths ratio, I really wonder why.  It's interesting that the curves go aligned as opposed to curled which is what I thought would happen."
Nov 3, 2016
Laurent Delrieu replied to Arthur Mamou-Mani's discussion Problems with angle force on polyline using Kangaroo 2?
"I made some change, add some anchor, the first segment. Change drastically the strengths, very low on angle and high on lengths. Work better. Tried a signed version of angle but it didn't worked"

Problems with angle force on polyline using Kangaroo 2?

Hi Guys,I am trying to visualise the changes in angles for the polyline shown in the image below.However I cannot get the bend force to work in this case, the resulting polyline seem to expand and wiggle in space. Any help would be great.Many thanks,ArthurSee More

Grasshopper at Burning Man Festival 2016!

Hi Guys,

We're building a project for the fourth year in a row at the Burning Man festival in Nevada US this summer. Spreading the parametric spirit to the world! This would have never happened without your constant support since the very beginning so thank you so much.

The project this year is called Tangential Dreams, a curvy tower made of straight lines following the tangents of a sine curve. This allows us to use off-the-shelf timber, minimise wastes and…

Save the Rhinos

Hi guys,

This post has nothing to do with the software but with the animal !
The Eastern Black Rhino is getting dangerously close to extinction, with only around 500 left in the wild.

Please help support the conservation effort by donating to this website:

Many thanks,

Arthur

Hi Arthur,

(Flat_circlepacking_ikerImage.gh)

I have manage to adapt this definition that Daniel Piker worked on(circle packing), o an image-field that defines the radii of the circles, but my main target is to optimize the radii for a better arrangement and population within the image-field allowing the radii to change and adapt during the simulation... some one posted in you tube a great video where they show this plus other interesting packing logic's....

here is the link:

http://www.youtube.com/watch?v=SSWudanJc7c&feature=related

any suggestions about to achieve similar results as image base/fighting for space....?

thanks

Iker

Hi again,

I have solved the problem this morning with 'surfacesplit' (since I was dealing with splines creating surfaces, and those needed trimming there where they were overlapping) + some 'list' and 'tree' paths that where not correctly setup.

Thanx.

Hi Arthur,

hope thiongs are well. - Not yet, I have done some trials with the 'region' and/or some of the 'surface' and 'intersect' tab utilities but with no luck. - The real issue is to delete overlapping surfaces...

In any case, thanx and let you know if I get a solution.

Arthur, thank you for your comment, in fact I used to have xausus.com but now  I doesn't have it now and I don't know  who seizes it now..

Thanks Mani, well, the method is very simple: we first need to create a rectangle based in a loft operation of some curves with control points, subdividing the surface, then we need a  surfacebox operation later the boxmorph with some geometry. We could  move the control points on one vector, and presto!,one organic flow.
