Pixel Art kot oblika digitalne umetnosti

Kous, Tajda (author), Urbas, Raša (mentor)

Pixel Art je oblika digitalne umetnosti, ki temelji na upodabljanju razpoznavnih elementov z omejeno barvno paleto ter uporabo mreže, sestavljene iz polj v velikosti enega piksla. Je ena od začetnih oblik 2D računalniške grafike in deluje po principu upoštevanja omejitev zmogljivosti starejših procesorjev in katodnih zaslonov (CRT; angl. cathode ray tube). Danes Pixel Art pridobiva na priljubljenosti zaradi popularnosti retro estetike in dejavnika nostalgije, prav tako pa je grafično nezahteven način razvijanja videoiger. Laiki ga pogosto enačijo s pikseliziranimi slikami, kar pa se zgodi zaradi zniževanja ločljivosti zaradi spreminjanja velikosti. To prepričanje je zmotno, saj je Pixel Art samostojna oblika digitalne umetnosti, ki zahteva precejšnjo količino vloženega časa in truda ter pri kateri se je treba ravnati po določenih smernicah. Diplomsko delo se ukvarja s tehniko Pixel Art ilustracije, pikselizacijo bitne oziroma rastrske grafike in razlikovanjem med pojmoma. V teoretičnem delu so razloženi principi računalniške grafike, digitalne umetnosti in sloga Pixel Art. Predstavljen je tudi pregled zgodovinskega razvoja računalniške grafike, saj je ta neposredno povezan s Pixel Art ilustracijo sodobnega časa. V eksperimentalnem delu so bile ustvarjene ilustracije v Pixel Art slogu in izdelane imitacije Pixel Art sloga, ki so bile analizirane in primerjane. V raziskavi diplomskega dela je bilo ugotovljeno, da se ilustracije od imitacij Pixel Art sloga vsekakor razlikujejo, a je opaznost razlike odvisna od upodobljene podobe. Izkazalo se je tudi, da najboljše približke Pixel Art slogu daje interpolacija najbližjega soseda.

• Title: Pixel Art as a form of digital art

Abstract

Pixel Art is a form of digital art based on the representation of recognisable elements with a limited colour palette and the use of a grid consisting of pixel-sized fields. It is one of the earlier forms of 2D computer graphics and is based on the principle of working with the limitations of older computer units and CRT monitors. Today, Pixel Art is growing in popularity due to its retro aesthetic and nostalgia factor, as well as the fact that it is a graphically undemanding way of developing videogames. Pixel Art is often equated with the pixelation of images that results from low resolution due to downsizing. However, this is wrong – Pixel Art is an independent form of digital art that requires a considerable amount of time and work and for which certain criteria must be met. This thesis deals with Pixel Art, bit-graphic pixelation and the distinction between the terms. The theoretical part explains the basics of computer graphics, digital art and Pixel Art style. It also covers the historical development of computer graphics, as it is directly related to today’s Pixel Art illustration. In the experimental part, Pixel Art style illustrations and imitated Pixel Art graphics were created. The results were compared and evaluated. The thesis investigation revealed that there is indeed a noticeable difference between Pixel Art illustrations and Pixel Art imitations, however, the visibility of the dissimilarity varies depending on the image depicted. It was also found that the best approximation to the Pixel Art style was achieved by Nearest Neighbour interpolation.
