Ben Kacyra: Ancient wonders captured in 3D

Prevoditelj: Davorin Jelačić Recezent: Tilen Pigac - EFZG

I'd like to start with a short story.

Volio bih početi s kratkom pričom.

It's about a little boy

Priča je o malom dječaku

whose father was a history buff

čiji je otac bio zaljubljenik u povijest

and who used to take him by the hand

koji bi uzeo sina za ruku i poveo ga

to visit the ruins of an ancient metropolis

u posjet ruševinama drevnog metropolisa

on the outskirts of their camp.

na rubovima njihovog logora.

They would always stop by to visit

Uvijek bi se zaustavili da posjete

these huge winged bulls that used to guard

velike krilate bikove koji su čuvali

the gates of that ancient metropolis,

kapiju te drevne metropole,

and the boy used to be scared

i dječak se plašio

of these winged bulls,

tih krilatih bikova,

but at the same time they excited him.

ali su ga istodobno i uzbuđivali.

And the dad used to use those bulls

Otac je koristio te bikove

to tell the boy stories about

da ispriča dječaku priče

that civilization and their work.

o toj civilizaciji i njihovim djelima.

Let's fast-forward to the

Premotajmo brzo

San Francisco Bay Area many decades later,

u zaljev San Francisca mnogo desetljeća kasnije,

where I started a technology company

gdje sam osnovao tehnološku kompaniju

that brought the world its first

koja je svijetu dala prvi

3D laser scanning system.

sustav za 3D lasersko skeniranje.

Let me show you how it works.

Pokazat ću vam kako to radi.

Female Voice: Long range laser scanning

Ženski glas: Lasersko skeniranje dalekog dometa

by sending out a pulse that's a laser beam of light.

slanjem pulsa koji je laserska zraka svjetlosti.

The system measures the beam's time of flight,

Sustav mjeri vrijeme putovanja zrake,

recording the time it takes for the light

bilježi vrijeme potrebno svjetlu

to hit a surface and make its return.

da pogodi površinu i vrati se.

With two mirrors, the scanner calculates

S dva zrcala, skener računa

the beam's horizontal and vertical angles,

vodoravne i okomite kutove zrake,

giving accurate x, y, and z coordinates.

i daje točne koordinate x, y i z.

The point is then recorded

Točka se zatim bilježi

into a 3D visualization program.

u programu za 3D vizualizaciju.

All of this happens in seconds.

Sve se ovo događa u sekundama.

Ben Kacyra: You can see here,

Ben Kacyra: Ovdje možete vidjeti,

these systems are extremely fast.

ovaj sustav je vrlo brz.

They collect millions of points at a time

Istovremeno bilježi milijune točaka

with very high accuracy

s vrlo visokom preciznošću

and very high resolution.

i vrlo visokom rezolucijom.

A surveyor with traditional survey tools

Tragač s tradicionalnim alatima za pretragu

would be hard-pressed to produce

bi vrlo teško zabilježio

maybe 500 points in a whole day.

500 točaka za cijeli dan.

These babies would be producing

Ove bebice proizvode

something like ten thousand points a second.

nešto kao deset tisuća točaka u sekundi.

So, as you can imagine,

Kao što možete zamisliti,

this was a paradigm shift

ovo je bio pomak paradigme

in the survey and construction

u traganju i graditeljstvu,

as well as in reality capture industry.

kao i u industriji bilježenja stvarnosti.

Approximately ten years ago,

Prije približno 10 godina,

my wife and I started a foundation to do good,

supruga i ja smo osnovali humanitarnu fondaciju,

and right about that time,

i, nekako u to vrijeme,

the magnificent Bamiyan Buddhas,

veličanstvene bamijske spomenike Buddhe,

hundred and eighty foot tall in Afghanistan,

visoke 60 metara,

were blown up by the Taliban.

Talibani su digli u zrak u Afganistanu.

They were gone in an instant.

Nestali su u trenu.

And unfortunately, there was

Nažalost, nije postojala

no detailed documentation of these Buddhas.

detaljna dokumentacija tih Buddha.

This clearly devastated me,

To me je, naravno, potreslo,

and I couldn't help but wonder about

i nisam mogao a da ne razmišljam

the fate of my old friends, the winged bulls,

o sudbini mojih starih drugova, krilatih bikova,

and the fate of the many, many

i o sudbini mnogih

heritage sites all over the world.

područja s kulturnom baštinom po svijetu.

Both my wife and I

I supruga i ja

were so touched by this

smo bili toliko dirnuti ovime

that we decided to

da smo odlučili proširiti

expand the mission of our foundation

zadaću naše fondacije

to include digital heritage preservation

i uključiti digitalno očuvanje baštine

of world sites.

takvih područja u svijetu.

We called the project CyArk,

Projekt smo nazvali CyArk,

which stands for Cyber Archive.

što znači kibernetski arhiv.

To date, with the help of

Do danas, uz pomoć

a global network of partners,

globalne mreže suradnika,

we've completed close to fifty projects.

završili smo blizu pedeset projekata.

Let me show you some of them:

Pokazat ću vam neke od njih:

Chichen Itza,

Chichen Itza,

Rapa Nui --

Rapa Nui --

and what you're seeing here

a ovo što tu vidite

are the cloud of points --

ovaj oblak točaka --

Babylon,

Babylon,

Rosslyn Chapel,

kapela Rosslyn,

Pompeii,

Pompeii,

and our latest project, Mt. Rushmore,

i naš posljednji projekt, Mt. Rushmore,

which happened to be one of

koji se pokazao kao jedan od

our most challenging projects.

najzahtjevnijih projekata.

As you see here, we had to develop

Kao što vidite, morali smo razviti

a special rig to bring the scanner

specijalni nosač kako bismo skener

up close and personal.

primaknuli blizu.

The results of our work in the field

Rezultati našeg terenskog rada

are used to produce

koriste se u proizvodnji

media and deliverables to be used

medija i objekata koje rabe

by conservators and researchers.

konzervatori i istraživači.

We also produce media for

Proizvodimo i medije za

dissemination to the public --

distribuciju u javnosti --

free through the CyArk website.

besplatni su putem CyArk stranica.

These would be used for education,

Oni su korisni za obrazovanje,

cultural tourism, etc.

kulturni turizam, itd.

What you're looking at in here

Ono što ovdje gledate

is a 3D viewer that we developed

je 3D preglednik koji smo razvili

that would allow the display

a koji omogućava prikaz

and manipulation of [the] cloud of points

i manipulaciju oblaka točaka

in real time, cutting sections through them

u stvarnom vremenu, koji izvlači sekcije

and extracting dimensions.

i izračunava dimenzije.

This happens to be the cloud of points

Ovo je oblak točaka

for Tikal.

za Tikal.

In here you see a traditional 2D

Ovdje vidite tradicionalni 2D

architectural engineering drawing

arhitektonsko inženjerski nacrt

that's used for preservation, and of course

koji se koristi za očuvanje, i, naravno,

we tell the stories through fly-throughs.

pričamo priče pomoću preleta.

And here, this is a fly-through

Ovdje imamo prelet

the cloud of points of Tikal,

kroz oblak točaka Tikala,

and here you see it rendered

a ovdje je to renderirano

and photo-textured with the photography

i foto-teksturirano pomoću fotografija

that we take of the site.

koje smo snimili na licu mjesta.

And so this is not a video.

Znači, ovo nije video.

This is actual 3D points with

Ovo je prikaz 3D točaka

two to three millimeter accuracy.

s točnošću od dva do tri milimetra.

And of course the data can be used

Naravno, podaci se mogu koristiti

to develop 3D models that are

za razvijanje 3D modela koji su

very accurate and very detailed.

vrlo točni i vrlo detaljni.

And here you're looking at a model

Ovdje gledate u model

that's extracted from the cloud of points

koji je konstruiran iz oblaka točaka

for Stirling Castle.

za dvorac Stirling.

It's used for studies, for visualization,

Koristi se za proučavanje, za vizualizaciju,

as well as for education.

kao i za obrazovanje.

And finally, we produce mobile apps

I konačno, proizvodimo i mobilne aplikacije

that include narrated virtual tools.

koje uključuju virtualne vodiče s naracijom.

The more I got involved

Što sam se više uključivao

in the heritage field,

u problematiku kulturne baštine,

the more it became clear to me

to mi je postajalo jasnije

that we are losing the sites

da gubimo lokalitete

and the stories faster than we can

i priče brže nego što ih

physically preserve them.

fizički možemo zaštititi.

Of course, earthquakes

Naravno, potresi

and all the natural phenomena --

i svi prirodni fenomeni --

floods, tornadoes, etc. --

poplave, tornadi, itd. --

take their toll.

uzimaju danak.

However, what occurred to me was

Ipak, ono što mi je palo na pamet

human-caused destruction, which was

je uništavanje od strane ljudi na koje

not only causing a significant portion

ne samo da otpada značajan udio

of the destruction, but actually

već se ono

it was accelerating.

i ubrzava.

This includes arson,

To uključuje paljevinu,

urban sprawl,

širenje gradova,

acid rain, not to mention

kisele kiše, da i ne spomenem

terrorism and wars.

terorizam i ratove.

It was getting more and more apparent

Bilo je sve vidljivije

that we're fighting a losing battle.

da se borimo u bici koju gubimo.

We're losing our sites

Gubimo naše lokalitete

and the stories,

i priče,

and basically we're losing

i zapravo gubimo

a piece -- and a significant piece --

dio -- značajan dio --

of our collective memory.

našeg kolektivnog pamćenja.

Imagine us as a human race

Zamislite da mi kao ljudska vrsta

not knowing where we came from.

ne znamo odakle smo potekli.

Luckily, in the last two or three decades,

Na sreću, u posljednja dva ili tri desetljeća,

digital technologies have been developing

razvijaju se digitalne tehnologije

that have helped us to develop tools

koje su pomogle da razvijemo alate

that we've brought to bear

koje smo donijeli

in the digital preservation,

u digitalno očuvanje,

in our digital preservation war.

u naš rat za digitalno očuvanje.

This includes, for example,

Ti su alati, na primjer,

the 3D laser scanning systems,

sustav za 3D lasersko skeniranje,

ever more powerful personal computers,

još moćnija osobna računala,

3D graphics,

3D grafika,

high-definition digital photography,

digitalna fotografija visoke definicije,

not to mention the Internet.

da i ne spomenem Internet.

Because of this accelerated

Zbog tog ubrzanog

pace of destruction,

tempa uništavanja,

it became clear to us that we needed

postalo nam je jasno da trebamo

to challenge ourselves and our partners

izazvati sebe i svoje suradnike

to accelerate our work.

na ubrzanje našeg rada.

And we created a project

I stvorili smo projekt

we call the CyArk 500 Challenge --

kojeg zovemo CyArk 500 Challenge --

and that is to digitally preserve

čiji je cilj digitalno očuvati

500 World Heritage Sites

500 lokaliteta svjetske kulturne baštine

in five years.

u narednih pet godina.

We do have the technology

Imamo tehnologiju

that's scaleable,

koja se može prilagoditi veličinom,

and our network of global partners

i naša mreža globalnih suradnika

has been expanding and can be expanded

se širi i može se širiti

at a rapid rate,

brzim tempom,

so we're comfortable

pa smo uvjereni

that this task can be accomplished.

da možemo izvršiti ovaj zadatak.

However, to me, the 500 is

Ipak, za mene je tih 500

really just the first 500.

zapravo samo prvih 500.

In order to sustain our work into the future,

Kako bismo nastavili naš rad u budućnosti,

we use technology centers

koristimo tehno-centre

where we partner with

u kojima smo partneri

local universities and colleges

lokalnim sveučilištima i fakultetima

to take the technology to them,

kako bismo im donijeli tehnologiju,

whereby they then can help us

a oni tada nama mogu pomoći

with digital preservation of their heritage sites,

u digitalnom očuvanju njihove baštine,

and at the same time, it gives them

a istovremeno dobivaju tehnologiju

the technology to benefit from in the future.

koja će im koristiti u budućnosti.

Let me close with another short story.

Završit ću s još jednom kratkom pričom.

Two years ago, we were approached

Prije dvije godine, suradnik

by a partner of ours to digitally preserve

nam je predložio da digitalno očuvamo

an important heritage site,

važan lokalitet kulturne baštine,

a UNESCO heritage site in Uganda,

područje UNESCO-a u Ugandi,

the Royal Kasubi Tombs.

kraljevske grobnice Kasubi.

The work was done successfully in the field,

Posao je uspješno završen na terenu,

and the data was archived

podaci su arhivirani

and publicly disseminated

i distribuirani javnosti

through the CyArk website.

putem CyArk stranica.

Last March,

Prošloga ožujka,

we received very sad news.

primili smo vrlo tužne vijesti.

The Royal Tombs had been destroyed

Kraljevske su grobnice uništene,

by suspected arson.

sumnja se na namjerno podmetnut požar.

A few days later, we received a call:

Nekoliko dana kasnije, primili smo poziv:

"Is the data available

"Jesu li podaci dostupni

and can it be used for reconstruction?"

i mogu li se koristiti za rekonstrukciju?"

Our answer, of course, was yes.

Naš je odgovor, naravno, bio: da.

Let me leave you with a final thought.

Napustit ću vas s jednom mišlju.

Our heritage is much more than

Naša baština je puno više od

our collective memory --

našeg zajedničkog pamćenja --

it's our collective treasure.

ono je naše zajedničko blago.

We owe it to our children,

Dugujemo svojoj djeci,

our grandchildren and the generations

unucima i naraštajima

we will never meet

koje nikada nećemo upoznati

to keep it safe

da je očuvamo

and to pass it along.

i proslijedimo dalje.

Thank you.

Hvala vam.

(Applause)

(Pljesak)

Thank you.

Hvala vam.

Thank you.

Hvala vam.

Thank you.

Hvala vam.

Well, I'm staying here because

No, ovdje sam jer smo vam

we wanted to demonstrate to you

željeli demonstrirati

the power of this technology

moć ove tehnologije

and so, while I've been speaking,

pa smo, dok sam govorio,

you have been scanned.

skenirali vas.

(Laughter)

(Smijeh)

The two wizards that I have

Dva čarobnjaka koja imam,

that are behind the curtain

koji su iza zastora,

will help me bring

pomoći će mi da prikažem

the results on the screen.

rezultate na ekranu.

(Applause)

(Pljesak)

This is all in 3D and of course

Ovo je sve u 3D i, naravno,

you can fly through the cloud of points.

možete letjeti kroz oblak točaka.

You can look at it from on top,

Možete ga promatrati s vrha,

from the ceiling.

s plafona.

You can look from different vantage points,

Možete gledati iz različitih kutova,

but I'm going to ask Doug to zoom in

ali ću zamoliti Douga da uveća

on an individual in the crowd,

na pojedinca u publici,

just to show the amount of detail

samo da vam pokažem količinu detalja

that we can create.

koje možemo stvoriti.

So you have been digitally preserved

I tako ste digitalno očuvani

in about four minutes.

u neke četiri minute.

(Laughter)

(Smijeh)

I'd like to thank the wizards here.

Volio bih zahvaliti našim čarobnjacima ovdje.

We were very lucky to have

Imali smo sreće da

two of our partners participate in this:

dva naša partnera sudjeluju ovdje:

the Historic Scotland,

Historic Scotland,

and the Glasgow School of Art.

i Glasgow School of Art.

I'd like to also thank personally

Također bih osobno htio zahvaliti

the efforts of David Mitchell,

Davidu Mitchellu na trudu,

who is the Director of Conservation

on je Direktor za očuvanje

at Historic Scotland.

pri Historic Scotland.

David.

David.

(Applause)

(Pljesak)

And Doug Pritchard, who's the Head of

I Doug Pritchard, koji je Direktor

Visualization at the Glasgow School of Art.

vizualizacije pri Glasgow School of Art.

Let's give them a hand.

Zaplješćimo im.

(Applause)

(Pljesak)

Thank you.

Hvala vam.
