Need to know the plu-in of some components

hi i need to use some components but i have really bad images of them, if someone could help me to figure out what is the plug-in would be awesome

this is the paper where i get the images https://www.researchgate.net/publication/342354407_Optimisation_of_Complex_Geometry_Buildings_Based_on_Wind_load_Analysis

Where did you get the images?

https://www.researchgate.net/publication/342354407_Optimisation_of_Complex_Geometry_Buildings_Based_on_Wind_load_Analysis

this is the paper

Have you read the paper? It says “ For this thesis, a tool based on the method was developed in Grasshopper, the visual scripting plugin for Rhinoceros3D. Existing plugins were used for the main algorithms while custom scripting was used to combine them into a single tool that was made relatively easy to use and returned quick results.”

So seems is custom scripted for that paper, try reaching the author.

yeah i try but without response, and just figure how to use almost everything, I don’t know about all de plug-ins for grasshopper, so I’m asking in case those components belong to one plug-in that I don’t know yet
