Abstract

Virtualna stvarnost (engl. Virtual Reality, VR) je skup tehnologija koje korisnika

„uranjaju“ u virtualno okruženje. Pritom korisnikova čula osjećaju samo virtualne

podražaje proizvedene računalom, a uz to je ostvaren izravan unos korisnikovih pokreta u

računalo. Virtualno okruženje predstavlja skup virtualnih predmeta koji se mogu

prikazivati. Sadržaj samog okruženja ovisi o primjeni, a budući da u virtualnom okruženju

nema fizičkih ograničenja poput gravitacije, sadržaj je u principu ograničen jedino maštom

kreatora. [1]

U radu je obrađena povijest virtualne stvarnosti i njene primjene danas te najbitniji faktori

koji ovu tehnologiju sprječavaju u postanku vodećeg nositelja svih društvenih mreža i

najkvalitetnije metode igranja virtualnih igara.

Eksperimentalni dio rada obuhvaća izradu virtualne scene, to jest virtualnog modela

grada, čiji su postupci objašnjeni i prikazani u programu Cinema 4D. Pomoću primjera

opisano je oblikovanje virtualnog predmeta iz jednostavnih geometrijskih tijela te su

obrazložene vrste selekcija. Manipulacijom reflektivnosti i refleksije dobiveni su virtualni

materijali koji podsjećaju na staklo i aluminij, a materijal kućne fasade postupkom izrade

teksture pomoću fotografije (mapiranje). Predstavljen je alat za povezivanje predmeta s

krivuljom, način upravljanja brzinom i vremenom gibanja pomoću Bézierove krivulje te

postupak animiranja pokreta. Detaljno je predočeno postavljanje zvuka u prostoru pomoću

virtualnih zvučnika te snimanje 3D zvuka uz pomoć virtualnog stereo mikrofona.

Prikazano je postizanje slike prostora u obliku virtualne stvarnosti skeniranjem refleksije s

površine materijala postavljenog na dvije sfere koje predstavljaju ljudski vid te prijenos

projekta u Adobe After Effects u svrhu dobivanja stereoskopske slike uz alat Adobe Media

Encoder.

Abstract (english)

Virtual Reality (VR) is a set of technologies where the user or player is completely

immersed in a virtual enviroment. While playing, the user's senses feel only the virtual

stimuli produced by a computer which is accomplished by a direct intake of the user's

movements into the computer. Virtual enviroment represents a set of virtual objects that

can be displayed. The content of the enviroment itself depends on the application, and since

there are no physical limitations such as gravity, the content is in principle limited by the

creator's imagination. [1]

This thesis discusses the history of virtual reality and its use today, along with the most

important factors which prevent this technology from becoming the leading provider of all

social networks and the best method for playing virtual games.

The experimental part of the project involves creating a virtual scene, a virtual city

model, whose actions are explained and displayed in Cinema 4D. The whole process of

designing a virtual object is described from the very beginning starting with Primitives and

using different tools and selections. It also contains an explanation of creating materials

such as glass and Aluminium, by manipulating the amounts of reflectance and reflection,

and the so called 'Mapping' technique or applying a picture on an object as its texture

material. There's an introduction to methods used to control speed, motion time and sound

by using the Bézier curve, which leads to a detailed presentation on how to record 3D

sounds in VR with a virtual stereo microphone. It's shown how to achieve a real VR effect

by scanning reflection from a material placed on two spheres representing the human

vision, importing the project in Adobe After Effects for the purpose of obtaining a

stereoscopic image and finally rendering it in Adobe Media Encoder.
