Europeana goes 3D
Daniel Ple1nckx Visual Dimension Belgium
This project has been funded with support from the European Commission‘s CIP ICT PSP programme

q Requirements of Europeana – All plaGorms – No soIware to install – User friendly – Support resource explora1on – Open and standard format
q Technical evolu1on – Jungle of OS/browser combina1ons – Breakthrough of HTML5/WebGL – Wide availability on desktop and mobile plaGorms (excl. Linux)
Publica1on of 3D for Europeana
![Page 3: 3D ICONS: Europeana goes 3D, Daniel Pletinckx, Visual Dimension Belgium](https://reader030.fdocuments.in/reader030/viewer/2022032420/55a4e1391a28ab9b0e8b478c/html5/thumbnails/3.jpg)
q 3DPDF – More features available in Acrobat (anima1on, …) – Security problem = > low end visualisa1on in browsers – Problem in Firefox, Chrome (altered behaviour) – OK in Safari, IE – mobile plaGoms: only limited support on iOS (Tech3D app)
q Pseudo3D – Panoramas and ObjectVR visualisa1on – Good plaGorms available (KrPano, Object2VR, Flashificator, …) – HTML5 output => all plaGorms – Excellent for interiors and sites – Solu1on for the difficult cases (glass objects, landscape, …)

q Unity3D/UnReal – Sector standard – Available on all desktop and mobile plaGorms – Self-‐installing free player – All required func1onality (complex interac1on with buildings) – Not standard format (HTML5 available)
q Remote rendering – WebGL interac1ve visualisa1on of low res 3D model – OK for objects, not for buildings and spaces – Good example (digitalsculpture.org) but not considered
Technical development

q WebGL – Support in Firefox, Chrome, Safari, IE (version 11), Opera – Support on all desktop & mobile plaGorms except iOS – Growing func1onality (point clouds, collision detec1on, …) – Most solu1ons are cloud based (central server, recurring cost)
q WebGL based streaming – Nexus format (CNR-‐ISTI) – Authoring by 3DHOP as web service (V-‐MusT) – Complex models with load 1mes of minutes visualise in seconds – Most flexible solu1on (server, func1onality, …)

q Applica1ons for object visualisa1on (mostly WebGL) – 3DHOP (vertex colours, all input formats in MeshLab) – SketchFab (conversion from 27 formats, large models) – 3DSOM (large meshes, streaming & compression)
q Applica1ons for walkthrough/guided tour – Coppercube (HTML5/WebGL + iOS)
q Applica1ons for point clouds – EcoSynth (TeraPoints) => MAP
WebGL solu1ons

q Type 1: objects and simple objects – Explore objects from all sides – Zoom in on details – Show specific views (front, side, top, …)
User experience
![Page 9: 3D ICONS: Europeana goes 3D, Daniel Pletinckx, Visual Dimension Belgium](https://reader030.fdocuments.in/reader030/viewer/2022032420/55a4e1391a28ab9b0e8b478c/html5/thumbnails/9.jpg)
q Type 2: complex buildings – Many interiors or complex scenes – Inside view and outside/birds eye view – Nearly all > 5 mio polygons
User experience
![Page 10: 3D ICONS: Europeana goes 3D, Daniel Pletinckx, Visual Dimension Belgium](https://reader030.fdocuments.in/reader030/viewer/2022032420/55a4e1391a28ab9b0e8b478c/html5/thumbnails/10.jpg)
q Type 3: sites – Terrain, vegeta1on, complex buildings or structures – Birds eye view – Ground level explora1on if sufficient 3D detail
User experience
![Page 11: 3D ICONS: Europeana goes 3D, Daniel Pletinckx, Visual Dimension Belgium](https://reader030.fdocuments.in/reader030/viewer/2022032420/55a4e1391a28ab9b0e8b478c/html5/thumbnails/11.jpg)
User experience
q Proper thumbnail q Download link where appropriate (e.g. 3DPDF) q Landing page
– Most op1mal viewing experience – Mul1ple audiences and uses
