Hoopsnake Iteration Component

Hi all,

 

Just wanted to announce the release of a component I was busy with the past few weeks called Hoopsnake. Here's a summary:

 

"HoopSnake, apart from a mythical creature, is simple component for Grasshopper. What it does in principle is to create a copy of the data it receives at it's input upon user request and store it locally. This duplicate is made available through a standard Grasshopper parameter output.

What turns this operation from mundane to actually promising is the fact that the input of the component includes some custom programming to escape Grasshopper's recursive loop avoidance check.

What this means in practice is that it is possible through the use of HoopSnake to send the output of a set of components back to it's input in a looping fashion. With the help of a little bit of Data Tree / Data List manipulation, this should open up some new possibilities for iterative process modeling. "

 

Read more/download at Volatile Prototypes.

 

Please let me know of any problems/feedback/questions you may have!

 

Cheers,

Yiannis

Very fun!  Can we take a look at the definition? What a classic.

Slider at 100 for testing, setting it at 1000 will take some RAM and time.

The t% parameter in the Similar component decides when to stop the loop.

Or just step by hand.

(Dont forget to clear all in Hoopsnake if you change something)

The non optimized version is probably easier to understand.

Hi Garcia, 

How did you manage to keep a trace of all your iterations ?

I am struggling to append my current object to a list.

Would there be a simple VB script to store all the loops?

Many thanks,

Arthur
