VB and working within a datatree..

hello guys,
I have a problem with a datatree..
I need to choose in every path that item, which has the most simular value to the item which was chosen in the preceding path.
So every selecting operation in any path has to compare with the result of the preceding operation.
(and additional: this operation should work several times independently within one data-tree.. (so I have paths in two layers))
my problem emerges because I…

Attractor Curve and Point


I'm new to grasshopper and I'm having trouble trying to create and attractor curve. 

I need the radius of the circles to be bigger as they get to the curves in green. In this case, the green curves would be attractor curves. Ideally, the radius of the circles also has to be bigger as the circles are closer to the center (where all curves intersect). In this case, the center point attractor would be "stronger" than the curve attractor. I'm not sure if…

Finding funicular forms using dynamic weights

Instead of using nodal forces that stay constant during form-finding, incorporating dynamic weights that update per time-step (depending on the current geometry) are interesting... not least because such systems converge when intuition says they should explode.

Such an approach means the final…

Dividing a curve to different lengths and different diameters


Im trying to divide this curve into 5 divisions where each will in turn be divided into a specific number of points that would serve as centers for circles of different diameters.

thus there are two variables, dividing the curve into 5 lengths where in each length it is divided in turn into different lengths and then introducing another parameter of having different diameters.

i have attached my very basic script however the result is not…

legend question

Does anyone know how to create a simple legend based on this algorithm used to create the following image? The color gradient goes from purple to red in the z direction, and colors points (faces) according to their location in the z direction from the lowest z value (purple) to the highest z value (red). I just want simple legend that shows a scale from purple to red in mm (also showing the values where other colors appear). I tried using the legend that comes with grasshopper, but it has a…

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…

Parrot 0.1 Release

The first pre release of Parrot is now available for download at the group:

Development of the .dll library and the .GHA plugin are underway now.

However I felt releasing the user object collection would allow for feedback about the direction the plugin should go, what is and isnt working, etc. So please let me know any thoughts you have on Parrot at the…

'Respecting' Voronoi

I recently had the (finally not so fantastic) plan to manipulate a Voronoi diagram so that I smuggle in my own polyline (1st image). I thought that relaxing all lines but my own could look awesome. It doesn't at all (2nd image), but I thought maybe it is useful or inspiring for someone else...…

53 Option: Is It a Scam?

I created a full fraud investigation and its outcome is clear: ratio choice isn't dishonest broker. the subsequent facts prove this while not a doubt:

•        It has the simplest websites and therefore the most versatile mercantilism platform on the trade. These price many thousands of greenbacks to form. Scammers wouldn't have these forms of resources at their disposal.

•        It has operated with none negative comments. Scammers will ne'er totally escape the negative…

Shatter multiple curves at their intersection points using Python

I wasn't able to use GH components to split several curves at the intersection points MultipleCurves(MCX) returned. At least, things looked like a mess. So I wrote sth. in Python. Maybe useful for someone else, too: Pastebin.
