algorithmic modeling for Rhino

Information

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.

support for HSB? 1 Reply

Just wanted to know if Volvox will (ever) support HSB color scheme, say for components like load.xyzawesome plugin btw :)Continue

We are organising a Volvox related workshop in the frame of the Advances in Architectural Geometry conference at ETH Zurich from 9-13. September 2016.

Some seats are still available for the workshop 10 "Scripting Reality – Integrating 3D Point Clouds in parametric design workflows"

This research-based workshop will introduce participants to thegeometrical class of point clouds and ways to handle, manipulate, analyse and script with them. Participants will as well have the chance to get first-hand knowledge in the handling of 3d capturing devices and to link their outputs directly into a design environment.

The workshop poses especially the question of how changes on architectural scale can be tracked over time. Related algorithmic concepts and the Volvox plugin, allow for the first time to directly access and manipulate point clouds in a parametric design environment, will be introduced to the workshop participants. A 1:1 experiment on the ETH campus will provide a testbed. Participants will learn point cloud processing and learn to track objects solely on the base of point cloud analysis, find deviations against the planned and visualise the results.

The workshop is led by Mateusz Zwierzycki, Martin Tamke and Henrik Leander Evers. FARO provides several 3d scanners with helical adapters and acccess to the FARO SDK for the workshop. The workshop is modestly priced with 160CHF.

register now.

The ability of Volvox to extract only the Scanner positions (poses) from Point Clouds in E57 format provides new efficient ways of handling large Scans of buildings. This, as one is typically only interested in a certain area or floor of a scanned building.

Having access to the Scan positions, without the need to load tens of Gigabytes, allows to quickly select and import only scans in a certain height and range.

Here a small GH definition, which uses the A-House Scan June E57 file from data.duraark.eu (10.4GB in size, 16 scans covering two levels) The GH definition allows to select and subsequently import:

a) only scans from a certain range in height - lower scans

upper

b) only scans in a certain range in XYZ direction

The definition is not very sophisticated, but demonstrates how Volvox and Point Clouds can integrate into Grasshopper workflows. The GH definition can be found   here

The scan can be directly downloaded from here

Here a full view on the A-house scan with 8% of points loaded:

Hey Mateusz,

I'm new to point clouds, so I'm not sure if my problem is with Volvox or just... general incompetence..

I'm attempting to convert a pointcloud I've been given into a mesh (I specifically need the very uneven floor). Its a Rhino Point cloud, and 30+mill points.

My first approach i'm attempting to utilise volvox to remove most of the unwanted data from pointcloud, (walls, columns etc) Then explore some different meshing techniques to generate appropriate floor mesh.

Does that sound sensible to you?

Hello machinestories,

using .ply format rhino opens this point cloud without problems. it has point, normal and color information. then using this c# script by david rutten this point cloud gets referenced to grasshopper (4.8 minutes needed in my pc). problem is that it outputs no normals (dont speak c# to pinpoint the problem).

then provided that the preview of the points is off i managed to work in grasshopper with 30million points.

best

alex

This sounds great. We had a recent project with 20 million points in e57 format. We ended up using cloudcompare which was a very good opensource tool. There is an e57 import plugin for rhino but it would just crash on import. Using cloudcompare I had to decimate the cloud quite a bit to bring it into rhino. Do you have any idea of what the point count limits are in rhino. Looking forward to having these capabilities in GH.

Comment by ng5 Alex on September 7, 2015 at 8:32am

oh this looks so great. 616ms !

lately i am working with point clouds coming from SfM software. i was trying to build a workflow in gh. this comes just right on time!! is there access to color data?

ok i am just gonna have to be patient for the approval.

Thanks Mateusz!
