Grasshopper plugin allowing the CityJSON format (https://www.cityjson.org/) to be opened in Rhino 3D and Grasshopper without the loss of semantic information. The primary focus of the plugin is to function on the 3D BAG data (https://3dbag.nl/en/viewer). However, the plugin is able to process other CityJSON files as well. The plugin consists out of multiple Grasshopper components exposing data in a format that is directly usable in grasshopper, and allows all this data to be baked into Rhino.
