Abstract
Generiranje i iscrtavanje terena Voxel prostora zahtjeva rastavljanje prostora na manje isječke za lakše ažuriranje i manipuliranje prostorom. Kako su algoritmi za generiranje terena Voxel prostora i modela isječaka velike složenosti i računski zahtjevni, potrebno je strukturirati aplikaciju na način da se rastereti glavna nit koja iscrtava prostor prebacujući zadatak generiranja terena prostora i modela isječaka na druge niti kako bi se osigurale dobre performanse aplikacije. Pri tome je važno osmisliti model komunikacije niti koji osigurava sigurni i sinkroni pristup podacima o isječcima. Generiranje realističnog terena Voxel prostora je moguće koristeći generatore 2D i 3D šumova te preslikavajući njihove izlazne vrijednosti koristeći dodatne uvijete ili linearne interpolatore za dodatno oblikovanje terena. Koristeći generatore šuma moguće je generirati špilje unutar terena te ukrasiti isječke postavljajući dekoracije čiji položaj ovisi o izlazu generatora šuma. Zbog proceduralno generiranog terena koji se razlikuje za svaki isječak, potrebno je optimizirati modele isječaka koji se iscrtavaju na zaslon na način da se uklanjaju stranice kocaka koje nisu vidljive virtualnoj kameri unutar prostora čime se smanjuje vrijeme potrebno za iscrtavanje cijelog prostora na zaslon te omogućuje učitavanje većeg broja isječaka u memoriju i iscrtavanje istih. Za prilagođavanje izgleda vodenih površina u prostoru koriste se prilagođeni programi za sjenčanje verteksa i fragmenata koji omogućuje dodavanje efekata valova i efekta refleksije izvora svjetlosti na površini.
Abstract (english)
Generating and rendering Voxel terrain requires splitting the Voxel space into smaller chunks which allows for easier terrain updating and manipulating. The algorithms used for generating Voxel space terrain and its model are complex and require lots of computing power. Structuring the application in a proper way is key to good performance of the application and is achieved by separating rendering from terrain and model generation into separate thread which require a good thread-communication model to ensure chunk data safety and synchronization. Genereating realistic Voxel terrain is posibble by using 2D and 3D noise generator and mapping their output using linear interpolators and additional conditions which can additionaly shape the terrain. Nosie generators are also used for generating caves inside the terrain and are also used to determine the placement of decorations. Because the terrain is procedurally generated, it is important to optimize chunk models by removing faces that are invisbile to the virtual camera inside the Voxel space. This ensures lower frame drawing time and allows for more chunks to be loaded into the memory and rendered. For modifying the appearance of water bodies across the Voxel terrain, custom Vertex and Fragment Shaders are used to create the effect of waves and light source reflection on the surface of the water.
