How to get the most out of your Grasshopper paths (Data.GH_Path) By Ben Silverman: BHSilverman[at]gmail[dot]com When developing custom components for grasshopper it is very helpful to master branch paths and utilize them to their maximum value. Branch paths are great for managing data and allow the user to perform complex geometric operations on very large datasets. However, Branch paths are elevated to awesomeness when you utilize them to add some building information modeling (BIM) to your grasshopper definition.

By controlling the branch paths of your data you can encode information into each item passing through a grasshopper wire from one component to another. This becomes very handy in interoperability tools that connect to building analysis software, where information on material properties becomes paramount. First thing to understand is the terminology. Tree Branches or List of Telephone Numbers? Access the branch by its path index as an Integer: Dim myPathIndex as Integer = 10 myDataTree.Branch(myPathIndex) GRASSHOPPER TUTORIALS.

Since I am using Attractors frequently in my research, I decided to spend some time on organizing a GH User Object which is basically a grasshopper component that takes an array of points attracted to a certain point and returns the new array of points. If you don’t know what a GH User object is the go here and type GH User). You can easily install this component by placing the file provided into the User Object Directory [ in GH File-> Special Folders -> User Object Folder]. Simple as that and it is ready to use in User tab in the GH toolbar under the category Digital[Sub]stance. The component has five different input values: the attractor, the point array, the field of attraction, the force of attraction and the visualization toggle.

The outputs on the other hand are the vectorfield of the attraction, the resulting point array and the visualization of the attraction range. The code might be containing some bugs so any feedback is deeply appreciated. Rate this: i Rate This Like this: [Sub]Code. This page is set up to host bits of codes and sample algorithms.
