This presentation by Daniel Pletinckx of Visual Dimension and 3D ICONS describes the requirements for publishing 3D media in Europeana. It discusses the developments in 3D PDF, Pseudo3D (panoramas), Unity3d/Unreal, Remote rendering, Web GL and Web GL based streaming, and 3DHOP (the 3D Heritage Online Presenter) developed by ISTI CNR. It then discusses the user experience of the various technical solutions and presents examples.

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

programme

2. 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

3. 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,
…)
Technical
development

4. 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

5. 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
