n the information given on the DigiCULT
online consultation platform, this theme was
stated to concentrate on the creation and re-
creation of digital historic heritage objects and
characters (e.g. avatars), architectural structures, and
archaeological or historic sites for interactive use in
augmented and virtual reality environments.
This includes:
tools for data capture and modelling in three
dimensions (including 3D GIS for cultural and
natural sites) with high accuracy in shape and
texture, tools for element extraction, virtual
reconstruction from fragments, etc.;
concepts and tools for expressive scene design
and scripting, and dynamic rendering and
seamless integration of animated 3D components
in augmented/virtual reality environments, allow-
ing multimodal interaction;
collections of, and non-textual, metadata for
reusable 3D components, VR building blocks,
avatars, etc.; definition of declarative exchange
formats and requirements for component-based
application development.

ctually all our tangible heritage is three-dimen-
sional (including material objects such as his-
toric records and manuscripts). Therefore, interactive
3D objects and environments are regarded as a key
area of research and development towards informa-
tion-rich representations of heritage objects, build-
ings, sites, etc., and new forms of mediating cultural
and historic knowledge. 3D objects and environments
may form part of virtual reality (VR) or augment-
ed reality (AR) simulations. What distinguishes such
simulations is that VR delivers an entirely computer-
generated `world', while AR, also often called mixed
reality, combines real with virtual elements to create
an environment to interact with.
On the question `What do you envision could
be achieved in this RTD area over the next 10-
15 years?', Martin Doerr (ICS-FORTH, Greece)
answered, `everything'. However, he pointed to lim-
itations and gaps in standardisation of VR formats
with enough flexibility, and the stability of such for-
mats. Furthermore, he saw a `missing connection of
