David Rutten replied to Arthur Mamou-Mani's discussion Incrementally rotate a line using VB.net, C# or python
"That is correct. If you want to get a curve from somewhere, modify the curve whilst making sure you don't modify the original, you have to duplicate the curve first."

"Hi Arend and Danny, Thanks a lot for your replies - problem fixed - The problem was not in the similarity but in the way we generated the numbers. Grasshopper was right and we were wrong :)"

Arend replied to Arthur Mamou-Mani's discussion Getting the index of consecutive duplicate numbers?
"Any example of a list of points? Any example of what you want with the output? (Cull the points, flag them). My JPEG to Grasshopper converter is currently broken, so posting your file might be quite useful."

Getting the index of consecutive duplicate numbers?

Hi Guys,We are trying to identify the index of two consecutive numbers in a same list (i and i+1) but are not getting the expected result with the following technique.We tried rounding the floating point numbers and changing the threshold but it didn't work. We thought it could be a decimal to binary issue maybe? How else could we…See More

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

Parametric Biodome in Chester

Hi everyone,



Here is the project i have been working on for the past 10 months at Proctor and Matthews Architects, we have just submitted the planning application:

http://www.architectsjournal.co.uk/5212434.article

Once completed it will be the largest freeform gridshell in the world.



Most of the roof structure has been worked out using Grasshopper.

Thanks a lot to everyone who helped on this… Continue

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.
