U ovom diplomskom radu je opisan i programski ostvaren algoritam za toon shading nacin sjen canja 3D modela, kao i popratna korisnicka aplikacija koja krajnjem korisniku omogu cava izvr savanje shader korisnickoga programa na grafi ckoj kartici ra cunala. Prikazan je na cin rada algoritma, kao i nacin implementacije kori stenjem JavaScript programskog jezika i JavaScript biblioteke.Neke od prednosti ovakvoga pristupa su mogucnost izvr savanja programskoga koda neovisno o platformi i operativnom sustavu, te jednostavnost implementacije. Uoceni nedostaci algoritma su nemogucnost implmentacije u jednoj iteraciji, sto u kona cni negativno utje ce na performanse aplikacije

This thesis describes and implements algorithm for toon shading of 3D models, as well as a supportingapplication which enables end user to execute shader program on computers graphic card.It also demonstrates how underlying algorithm works, as well as implementation of it using JavaScriptprogramming language and JavaScript library. Some of the advantages of this approach arecross platform and operating system independent execution of application, as well as ease of implementation.Observed disadvantage of this approach is forced use of multipass rendering, whichhas negative impact on applications performance.
