Pretvorba 3D modela v Pixel art grafiko

Pecl, Primož (author), Iskra, Andrej (mentor)

V tej nalogi se primerjata Pixel Art in 3D grafika, namen pa je bila izvedba pretvorbe 3D modela v Pixel Art grafiko z uporabo dveh metod. Prva metoda poteka v programu za 3D modeliranje, druga pa s pomočjo zunanjega programa, imenovanega kar Pixel Art Shader. Najprej smo raziskali samo zgodovino in lastnosti Pixel Arta. Zatem smo pojasnili še razvoj 3D grafike, njeno delovanje ter našteli še nekaj načinov njene izdelave. Ker je bil za potrebe naloge izbran 3D modelirni program Blender, je nekaj besed namenjenih tudi njemu. Oblikovati je bilo potrebno dva testna modela za pretvorbo, to sta bila fantazijski čajnik ter skodelica. Sam postopek oblikovanja smo, bolj na splošno seveda, tudi predstavili. Oba modela smo oblikovali s pomočjo poligonskega modeliranja, za osnovo pa je služil primitivni objekt, imenovan valj. Nato je sledila pretvorba s pomočjo obeh metod, kar je seveda dalo različne rezultate. Pričakovano je bilo, da se bo druga metoda odrezala dosti bolje, v primerjavi s prvo, čeprav je bila dosti bolj težavna. Druga metoda je ponudila vrsto različnih prednosti. A kljub temu smo na koncu prišli do zaključka, da bi se moral sam Pixel Art Shader še poenostaviti, da bi lahko bil uporabnejši v širšem smislu. Zgled bi mu lahko bil shader, ki se uporablja pri programu Unity.

• Title: Converting 3D model into Pixel Art graphic

Abstract

This thesis presents a comparison between Pixel Art and 3D graphics. Its goal is conversion of 3D model into Pixel Art graphics, with the use of two methods. The first method is achieved in 3D modelling program, while the second one uses an external program, called simply Pixel Art Shader. At first we delved into history and characteristics of Pixel Art. Afterwards we explained the development of 3D graphics, its characteristics and presented the methods of its creation. We also dedicated some words to 3D modelling program, called Blender, because it was used to achieve the goal of this thesis. We created two models for its purpose. Those were fantasy styled mug and a cup. We also described the creation of those models, albeit in a more simplified fashion. Both models were created with polygon modelling method and were based on cylinder object. The next step became conversion with the help of before mentioned methods, which gave us different results. That being said, it was expected for the second method to perform much better than the first, despite being harder to achieve. It offered many advantages, compared to the first one. Despite that however, we concluded that Pixel Art Shader will still have to be immensely improved in order to be more useful on a larger scale. A good example for it could be shader that is currently being used in Unity.
