Abstract

U ovom radu opisan je cjelokupni proces proceduralnog generiranja krajolika kroz faze
generiranja i teksturiranja terena te postavljanja pokrova. Predstavljeni su algoritmi razina
detalja za teren te je detaljno objašnjena Lindstrom-Koller metoda simplifikacije. Ukratko
su opisani postupci teksturiranja terena te je detaljnije objašnjena metoda miješanja
tekstura detalja s obzirom na parametre tla. U nastavku su predstavljene različite metode
prikaza trave i stabala te su predložene optimizacijske metode za njihovo efikasno
iscrtavanje. Opisani su različiti algoritmi nasumičnog razmještanja koji su potom korišteni
za vizualno uvjerljivo postavljanje pokrova. Konačno, predstavljena je implementacija
generatora krajolika postupcima prezentiranima u ovom radu te je napravljena usporedba
između stvarnih krajolika i njihovih proceduralnih inačica.

Abstract (english)

This thesis describes an overall process for procedural generation of environments through
terrain generation, texturing and placement of terrain cover. Algorithms for terrain level of
details were presented with detailed description of Lindstrom-Koller simplification
method. Different approaches to terrain texturing were given with emphasis on a texture
splatting technique based on ground parameters. Furthermore, various methods for
modeling grass and trees were presented and algorithms were proposed for their efficient
rendering. Scattering algorithms were described and used for achieving visually attractive
yet random placement of terrain cover. Finally, an implementation of given techniques is
presented and comparison given between real landscapes and their procedurally generated
representations.
