Abstract
Namen diplomske naloge je vgraditi osnovne funkcionalnosti aplikacije NeckVeins v spletno aplikacijo in pri tem dokazati, da je možno vgraditi enakovredne funkcionalnosti na spletu. V diplomskem delu je opisan postopek izdelave spletne aplikacije za vizualizacijo volumetričnih podatkov žil, pridobljenih iz naprave CT. Sprva so predstavljene vse uporabljene tehnologije, nato je predstavljeno predelovanje urejevalnika Three.js za potrebe diplomske naloge. Opisan je postopek vgrajevanja funkcionalnosti prikazovanja in upravljanja objektov. Prav tako je predstavljen glavni del diplomskega dela, ki predstavlja odpiranje in prikazovanje parov datotek Mhd in Raw s pomočjo Marching cubes algoritma s poskusno spletno tehnologijo WebCL. Nazadnje so predstavljeni rezultati meritve hitrosti obdelave podatkov v spletni aplikaciji in namizni aplikaciji NeckVeins ter meritve hitrosti izrisovanja v spletni in namizni aplikaciji. Pri tem je ugotovljeno, da ni bistvene razlike v hitrosti obdelovanja podatkov. Pri samem izrisovanju predmeta, ko miruje in ko ga rotiramo, pa se izkaže, da je spletna aplikacija počasnejša.

Title:Visualization of 3D medical images on the web using WebCL
Abstract:
The main goal of this thesis is to implement the basic functionalities of the NeckVeins application in to a web application and by that proving that it's possible to implement the same functionalities on the web. This thesis describes the process of developing a web application for visualization of volumetric data of veins from a CT machine. In the beginning of this thesis all the used technologies are described. The description of editing the Three.js editor for the purpose of this thesis follows. In it we describe the functionalities of displaying and controlling the objects. Then we describe the biggest part of this thesis which is the support for opening and displaying pairs of Mhd and Raw data with the algorithm Marching cubes implemented with the experimental WebCL technology. Lastly we describe our speed measurements of the web and the desktop NeckVeins application in which we conclude that there is no major difference in speed of processing data, but there is a big speed gap between the speed of drawing frames. It's concluded that the desktop application is much faster when it comes to drawing single frames.
