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.

Large .las files
Hi guys.
I am trying to explore Volvox for import of large pointclouds (>7gb) from 3D scan.
The file is .las and is more than 7 gb of size.
Is Volvox to open .E57 files only, meaning that the .las file needs to be converted first in CloudCompare?
I am having quite some problems opening this file in CloudCompare as it seems there is problems with the large file size.
Does anybody have a good best practice for this?
I am glad to explain more - if I can :)
Best regards Rasmus

Hi Rasmus
LAS is a binary format similar to e57. so one cannot "simply read it" like ASCII formats and writing an importer takes quite an effort (ask mateusz :-) )
I dont see a way around converting the file either in cloudcompare or another tool into e57. This requires lot of RAM required - we have such computers here...
Processing 7GB will be a problem anyahow. so either you subsample massively and/or you just load a subset of scan positions (if it is a terrestrial laserscan and not a Aerial)
Volvox allows to inspect scan positions before importing and to import only a subset of these. this is handy for processing. One can make a handy batch routine, where a massibe Pointcloud is broken down into smaller chnunks and finally written out as one subsampled e57.
hope this helps - else come back here

Hello Rasmus,
you can also try and convert the las file to txt or xyz. Volovx handles really well txt files, though the max file size i have used is is 2.5gb.
best
