Abstract

U ovom radu, prikazane su metode prikaza i simulacije ljudske kose. Implementacija je pisana u OpenGL-u. Opisane su metode prikaza, modeli osvjetljavanja, anti-aliasing, razina detalja, simulacija kovrčave kose te nasumična varijacija. Prikazane su dvije vrste interpolacije dlaka kose. Osim prikaza kose, objašnjena je i fizikalna simulacija kose. Korištena je Verlet integracija za izračun pozicija i brzine. Opisana su fizikalna ograničenja na model koja održavaju oblik kose. Vjetar je simuliran kako bi uveo nasumičnu promjenu pozicije dlaka kose. Priloženi su programski kodovi sjenčara geometrije, sjenčara teselacije te sjenčara fragmenata.

Abstract (english)

In this thesis, human hair rendering and simulations methods are presented. The implementation was written in OpenGL. Rendering methods, shading methods, anti-aliasing, level of detail, curly hair simulation and random variation are described. Two types of hair interpolation are presented. Apart from rendering, physically based simulation is explained. To calculate speed and position, Verlet integration is used. Physical constraints which preserve the shape of the hair are described. Wind is simulated to bring random change to the position of the hair. Geometry shader code, Tessellation shader code and fragment shader code are shown.
