3D Digitisation of Icons of European Architectural and Archaeological

Heritage (3D Icons) project is a pilot project funded under the European

Commission’s ICT Policy Support Programme, built on the results of

CARARE and 3D-COFORM.

3D-ICONS proposes to digitize a series of architectural and

archaeological masterpieces of world and European cultural significance

and provide 3D models and related digital content to Europeana, with

the aim of contributing to the critical mass of highly engaging content

available to users.

The project will exploit existing tools and methods, to integrate them in a

complete supply chain of 3D digitization to contribute a significant mass

of 3D content to Europeana.

The project will focus on UNESCO World Heritage monuments and other

monuments of outstanding value at European level, to illustrate a

particular strand of Europe’s history.

The digital content will include overall 3D models and reconstructions, enlarged

models of important details, images, texts, videos. It will also include and re-

contextualize in 3D, objects belonging to a monument but presently located

elsewhere, for example in a museum.

Technology

• 3D model generation via

- image-based modeling, requiring mainly a digital camera;

- 3D scanning, a medium- or long-range 3D scanner required;

- procedural modeling and 3D sketching, using free or inexpensive specific software

• 3D model and digital information storage management: requires standard

computer resources and an open source repository management system

• 3D visualization tools: open source or free software

The softwares used in the project are based mainly on open-source

technologies or on technologies that have a low acquisition costs.

Besides the 3D content that the project intends to make available to the

general public, another important task is to make publicly available the

production pipeline to other cultural institutions or owners of 3D cultural

content.

Photogrammetry offers accurate results, being a method suited for personnel

from cultural heritage domain, with a limited technical background, but as

well it is able to deliver measurable, accurate and detailed 3D information.

Web visualisation

• Possibility to visualize different level of information

• Segmented information may lead to historical interpretation by analyzing models

which are located in different places, but belong to the same culture

• Visualisation for the public

• Visualization and usage by cultural heritage experts , which us still considered as a

medium to reach the public, rather than a basic instrument for research and

conservation

Web-based vizualisation offers the possibility for documentation of heritage sites

and artefacts at different scales and resolutions for applications such as

conservation, restoration or education

3D replicas communicate in an effective way

Characteristics such as metrics, accuracy and photorealism should be taken

into consideration when it comes to study and research
