Grasshopper
Volvox
Volvox enables you to create, edit and analyze Point Cloud data. You can download it from food4Rhino.
The plugin is developed in the frame of the DURAARK project: http://duraark.eu/
DURAARK (Durable Architectural Knowledge) is a collaborative project developing methods and tools for the semantic enrichment and long-term preservation of architectural knowledge and data. It focuses on establishing working practices and links between semantically rich BIM models and unstructured Point Cloud data. It Is funded through the European Commision's FP7 Programme and is running between 02/2013 - 01/2016. (Grant Agreement no: 600908)
This plugin is developed as a part of DURAARK project at the Center for Information Technology and Architecture (CITA) by Henrik Leander Evers and Mateusz Zwierzycki.

Point Set Deviation Procedure
Hi,
I am new to using Volvox in grasshopper. I am trying to replicate the Point Set Deviation command found in Rhino. Would anyone be able to guide me on a procedure for this? I found an example of it used in this article: http://papers.cumincad.org/data/works/att/ecaade2016_171.pdf but am having a hard time trying to develop the correct process in grasshopper. I'm not sure if the "Mesh Compare" command in UserData is used for this or not...
Any tips or guidance would be much appreciated. Thanks in advance!

Figured it out, quite easy in hindsight! Mesh Compare was the starting point. My stumbling block was figuring out the 'keys' which seems to just be an arbitrary tag for storing data. I needed to assign colours to deviations and use Preview Data (from Volvox) for visualization.
