Presentation at the Digital Museum Expo in Amsterdam, about the publication of 3D assets (in the context of the European 3D-ICONS project) on Europeana

1. Europeana
goes
3D

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

2. Publica1on
of
3D
for
Europeana
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)

3. q 3DPDF
– More
Technical
development
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,
…)

4. q Unity3D/UnReal
– Sector
standard
– Available
Technical
development
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

5. q WebGL
– Support
Technical
development
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,
…)

7. 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

8. q Type
1:
objects
and
simple
objects
– Explore
objects
from
all
sides
– Zoom
in
on
details
– Show
specific
views
(front,
side,
top,
…)
User
experience

9. q Type
2:
complex
buildings
– Many
interiors
or
complex
scenes
– Inside
view
and
outside/birds
eye
view
– Nearly
all
>
5
mio
polygons
User
experience

10. q Type
3:
sites
– Terrain,
User
experience
vegeta1on,
complex
buildings
or
structures
– Birds
eye
view
– Ground
level
explora1on
if
sufficient
3D
detail

11. User
experience
q Proper
thumbnail
q Download
link
where
appropriate
(e.g.
3DPDF)
q Landing
page
– Most
op1mal
viewing
experience
– Mul1ple
audiences
and
uses

12. Example:
Ename
q Exis1ng
3D
models
for
3D-­‐ICONS
q Historical
landscape
reconstruc1on
(1020
–
1730
in
9
periods)
q Very
complex
scenes
(30
–
60
billion
polygons)
q 3D
and
