Hoopsnake is a component that enables feedback loops within 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. 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.

I have tested this project, but it might contain still bugs. Please use it "as is", it does not come with warranties.

To install:

  • In Grasshopper, choose File > Special Folders > Components folder. Save the gha file there.
  • Right-click the file > Properties > make sure there is no "blocked" text
  • Restart Rhino and Grasshopper
