Join Chris Reilly for an in-depth discussion in this video Manipulating list data with filters, part of Learning Grasshopper.
…Let's talk about some more advanced ways of manipulating list data in Grasshopper.…Here, we'll be using components from the Sets,…Lists, and Sequence Component Panels.…In our first example, we'll take a look at List item.…So that's under Sets, List.…List Item selects one item from a list specified by its index.…So here, we have five circles that we created in Rhino,…defined locally into this geometry parameter.…That Geometry List flows into the List items List input.…
And a number slider determines the index of the data returned by the list item.…Finally, the single item returned by list item passes to…an extrude component which makes a cylinder using a circle as a profile.…Extrudes direction parameter has been set locally to 002,…making an extrusion that's two units high in the Z direction.…By changing the value of the slider, we tell the list item component to…pick a different circle from the list and apply the extrusion.…List item, also has a wrap input, and this is defined as a default value of true.…
