3D World Heritage at your fingertips: what to expect? Daniel Pletinckx Visual Dimension Belgium

This project has been funded with support from the European Commission‘s CIP ICT PSP programme

Online delivery Serve a wide variety of users Accessibility Easy of use Engagement

Europeana requirements Visualisation on ALL major platforms Avoid installation of additional software Intuitive and easy Resource exploration Open and standard file formats

Online 3D = Quickly changing technology

Online delivery of 3D data in CH

Linked Heritage

Current providers of 3D in Europeana

CARARE

3D-COFORM

Natural Europe Project

Evolution of online 3D visualisation – Rise of mobile browsing (15 %) – More browsers => Chrome, mobile browsers – More operating systems: iOS, Android, Windows Mobile, Firefox OS

Technologies – 3D PDF – HTML5/WebGL – Serious Games (Unity3D, UnReal) – Game solutions in social media – Pseudo3D (HTML5) – Remote rendering – Flash

Key Technologies

Pro – More functionality (animation, …) – Uptake by the CH community

Con – Security issues (PDF in browser) – Superseded by simple PDF readers in browsers – Limited availability on mobile platforms (iOS)

3D PDF

Pro – Available on all platforms (except iOS) – No software to be installed – Maximum use of GPU power – Platform independent

Con – Is new, so missing functionality

Technologies – Nexus (streaming) – Point cloud – Object viewers – Scene viewers

WebGL/HTLM5

Pro – Good visualisation within seconds of complex objects – Available as web-service for publication on own server – Can visualise objects without simplification/optimisation

Con – Limited to colour per vertex objects – Is new

Nexus (WebGL)

Pro – Quick visualisation of complex objects – Can visualise objects without meshing/optimisation/simplification

Con – Low interactivity – Limited to colour per vertex data

Point Cloud visualisation (WebGL)

Pro – Large number of formats supported – webservice

Con – Limited to objects – Resides on foreign server – IPR

Object visualisation (WebGL)

Pro – Deals with complex and vast spaces, inside and outside – Motion along a path (guided tour)

Con – Path to be designed manually

Scene visualisation (WebGL)

Pro – Better interaction with complex space (collision detection, terrain) – Tools for publishing to different media – Highly optimised web-viewers

Con – Manual design of functionality – No standard or open format

Serious games (Unity3D, UnReal)

Pro – Deals with complex and vast data, independent of PC power – Combination of panoramas, rendered animations, ObjectVR – Highest quality of images – Deals with special cases (glass, reflection, vegetation, …) – Allows to visualise 4D

Con – Interactivity to be designed

manually

Pseudo3D (HTML5)

Example: Ename

Ename 1065 – pseudo3D

Example: Ename
