Learn how data flows in nested lists through components in Grasshopper. This tutorial shows how to manage the data tree, as well as how to use the Param Viewer and how to use the Panel component to visualize data flow.
- [Instructor] In this chapter, we'll work through…several examples that rely on managing the data tree…as it flows through our Grasshopper definitions.…Back in chapter six of the Learning Grasshopper course,…we covered in-depth working with lists and the data tree.…I'd highly recommend watching or re-watching those videos,…but in this video, I'd just like to do a little crash course…reviewing how components handle multiple lists…at the same time.…So I've got a blank Rhino file open.…And the exercise file 0010-tree-basics.gh…open in Grasshopper.…And in this example, I've got three simple curves…internalized into a geometry parameter.…
And I'd like to take a look at how the data is flowing…from this parameter,…so I'm going to go ahead and connect it…to a divide curve component.…You can see what happens in the Rhino window.…Each curve is divided into a set of points.…And I can control the number of segments,…which determines the number of points,…through the divide curves count parameter.…So I'll set this, to say, four for now.…
