STW | 3D technologies and open digitized collections
- 1. Athena Giustiniani Statens Museum for Kunst CC0 Introduction to 3D technologies and open digitised collections Jonathan Beck Founder and manager, Scan the World
- 2. Largest online platform for 3D printable objects of cultural significance. Contributed by either a community of enthusiasts or an internal team working on an official capacity with institutions. Everything is uploaded with appropriate metadata and backlinks to institution’s online databases. Free to download with licensing varying on the institution. Non-profit, community built initiative archiving cultural artefacts Scan the World
- 3. 3D Imaging Virgin and Child Fitzwilliam Museum, Cambridge CC-BY-NC 2.5 How do you scan?
- 4. Cheap Accessible Open-Source technology Exports photographic texture Calculating dimension not intrinsic to process Slow processing Learning curve Photogrammetry Series of overlapping photographs to produce a 3D representation of an object or environment Experimented with as early as 1860 by artist François Willème Can use a single digital camera (or smartphone) to produce a nice quality scan
- 5. Photogrammetry Software: - Agisoft Photoscan - RealityCapture - Autodesk ReCap - Meshlab (free)
- 6. Structured Light Comprised of two cameras and a projector, either handheld or placed on a tripod Familiar pattern projected onto surface, distortion to the pattern is recorded by the camera’s sensors 100 micron point accuracy with more guaranteed quality Less learning curve Immediacy of data capture Discrepancies in texture capture Expensive Size limitations
- 7. Structured Light Hardware: - Artec Eva (30cm+) - $$ - Artec Spider (-30cm) - $$ - Artec Leo - $$$ - HP DAVID 3D - $$ - Shining3D Einscan Pro - $ - Creaform Go - $$$
- 8. Lidar Infrared laser scanning Tripod fires points out from the rangefinder, differences in laser return times and wavelengths produce a ‘point cloud’ of three dimensional data Can scan most materials, ranging from translucent materials to chemical compounds and singular molecules
- 9. Additive Manufacturing Kneeling Angel Fitzwilliam Museum, Cambridge CC-BY-NC 2.5 3D Printing
- 11. FDM - Fused Deposition Modelling Rapid prototyping, modelling, maquettes Cost-effective means of production Filament is generally a plastic composite
- 12. SLA - Stereolithography Resin based additive manufacturing High precision, small, intricate shapes Used in jewellery and modelmaking as is easy to cast post production
- 13. SLS - Selective laser sintering Powder based printer, fused layer by layer with lasers Doesn’t produce support material (as seen in FDM and SLA printing) Prints polymers such as nylon and polystyrene, steel, titanium and alloy mixtures.
- 14. OpenGLAM + Open Digitised Collections Antinous as Dionysus Statens Museum for Kunst CC0 Releasing digitised museum collections with an open license (CC0) Inspiring new knowledge, creativity, access and interpretations Breaking the collection beyond the museum’s walls to bring a global audience back to them Just 1% of many museum collections are on display, the digital is the only place to present this If a museum’s collection isn’t online, it doesn’t exist
- 15. What does a museum’s collection mean to those who are partially sighted or blind? Traditionally enforced museum rule of ‘do not touch’ makes accessing culture close to impossible for people who have visual impairments. 3D printing allows for the cheap production of high quality facsimiles which in tern, provides someone with the incredible experience of engaging with artefacts. Use cases - Accessibility Torso of a soldier Musée de Mougins, France CC-BY-NC 2.5
- 16. Use cases - Education Uses for students, drawing classes can use 3D reference rather than 2D images Object based learning Scanathons - learn about the art and the technology!
- 17. Use cases - Reinterpretation Niv Shafran 2017 Open data means a continued conversation outside of the museum’s walls Remixing and reinterpretations of collections allows for a new voice to be added to the museum’s ecosystem
