Abstract
Iscrtavanje 3D objekata je postupak koji ima veliku važnost u modernom svijetu. Mnogo tehnologija i grana znanosti se oslanja na iscrtavanja da bi bile korisne. Iscrtavanje se velikom većinom standardiziralo u vrlo jednostavan postupak. Sve započinje vertex shaderom čija je zadaća da preuzme podatke objekta koji se iscrtava te da ih određenim postupcima transformira u nešto korisno. Nakon vertex shadera se izvršava fragment shader koji uzme podatke proizvedene u vertex shaderu te ih iskoristi da bi se proizveli pikseli koji se iscrtaju i prikažu korisniku. Takav klasični pristup iscrtavanju je veoma jednostavan no ima nedostatke kada su u pitanju modeli s velikim brojem trokuta. Rješenje za razne probleme klasičnog iscrtavanja daju modeni mesh shaderi. Oni mijenjaju logički slijed iscrtavanja te daju drastično veće mogućnosti i sposobnosti korisniku. Moderno iscrtavanje započine s task shaderom koji uzme podatke objekta te odlučuje koji dijelovi objekta se trebaju iscrtavati, a koji ne. Task shader zatim pokreće jedan mesh shader za svaki dio objekta koji je vidljiv. Mesh shader zatim izvodi učitavanje i postavljanje podataka za iscrtavanje. Nakon mesh shadera se poziva fragment shader koji proizvodi piksele identično kao i u klasičnom slučaju. Budući da je struktura podataka drukčija u modernom slučaju napisan je algoritam koji pretvara obične mesheve objekata u oblik pogodan za moderne shadere. Rezultati modernih shadera su vizualno identični kao i klasični, ali postupak je višestruko učinkovitiji te ima mnogo bolje performanse. Performanse moderne metode su redovito više od 3 puta veće od klasičnog iscrtavanja.
Abstract (english)
Rendering 3D objects is a precedure of great value in the modern world. Many technologies and sciences rely on rendering in order to be useful. Rendering has largely standardized into a very simple procedure. It begins with a vertex shader whose job it is to take the object data and process them in some way in order to transform them into something useful. After it comes the fragment shader which takes the vertex shader data and uses it to produce individual pixels which are then rendered and displayed to the user. The classic way of rendering is very simple but has some downsides when it comes to models with a large number of triangles. The solution to the problems come in the form of modern mesh shaders. They completely change the logic of rendering and in doing so have far more features and capabilities. Modern rendering starts with the task shader which uses the object data to determine which parts are visible and which are not. It then starts executing a mesh shader for every part of the object that is visible. The mesh shader then loads and sets the data that needs to be rendered. After it comes the fragment shader which is virtually identical to the classic case. Considering that the data structure is different an algorithm was written which converts the usual object mesh into a form usable by the modern shaders. The resulta of the shaders are visually identical to the classic case, however the procedure is much more efficient and has better performance. The performance is regularly over 3 times greater than the classic case.
