3D scanning, projection mapping, projections: Joanie Lemercier

3D SCANNING.

‘It is basically a 3 dimensional version of a photography, but the scanning process captures and stores the shape/structure of the subject.
The 3d scan is then stored as data, can then be archived, duplicated, 3d printed, distributed and shared online, viewed on a screen or in an immersive environment, like a virtual reality headset or a stereoscopic display.

Some museums are already using 3D scans:
– London’s science museum is selling 3D printers and offering virtual tours of laser scanned galleries.
– the Smithonian is scanning for archival purposes
– the Met is going even further by creating conversations and engaging with it’s audience during workshops.

A few have even started scanning and sharing their collections online:
– The Metropolitan Museum of Art (75 objects)
– The Smithonian (26 models)
– The British museum (14 models)
– Lincoln collection (74 objects)
– The Google cultural institute is also building a database of 3D scans.
It is still a rare practice, and despite the relatively small online collections, a single object can generate a large number of interactions, with 22.500 views and 1.100 downloads for the “Granite head of Amenemhat III” alone.

While the scanning process was very expensive a few years back, it has now become very accessible (thanks to the photogrammetry softwares) and anyone can now 3d scan any object, within seconds, with a simple smart phone, and museum visitors generate their own scans / 3d data:
– Sketchfab has a large amount of meshes (no precise stats)
– 123d website offers 576 models
– Thingiverse has 2.000 models, user-generated scans from museums, freely available for download.’

Using the Sketchfab archive of model meshes:

The artist created a 3D scan of the sculpture using a software called ‘Agisoft Photoscan’- I am going to test out this software to try and create similar mockups of 3D prints e.g. terrain, architecture facades.
