Detailed Description

Razred Renderer predstavlja apstrakciju sustava za iscrtavanje. Sama implementacija parsiranja grafa scene, primjene odgovarajuæih transformacija te konaènog prijenosa podataka za iscrtavanje je ostvarena ugraðenom OSG-ovom funkcionalnošæu.

Meðutim, postupak je proširen vlastitim shader programima. Na taj naèin, omoguæeno je kvalitetno per-pixel osvjetljenje (klasiènim Blinn-Phong modelom), te dodatni efekti poput prozirnosti i highlight-a objekata.

Takoðer, za implementaciju nightvision mode-a, potreban je dodatan postprocessing prolaz, koji obraðuje veæ iscrtanu sliku, primjenjujuæi odgovarajuæi filtar. Ovo je ostvareno proširivanjem poèetnog grafa scene dvijema dodatnim kamerama. Prva kamera iscrtava poèetni graf scene, i to u teksturu jednakih dimenzija kao prozor za iscrtavanje. Druga kamera iscrtava teksturirani pravokutnik preko cijelog ekrana. Naravno, tekstura tog pravokutnika je dobivena obradom teksture koju generira prva kamera, a što je sve implementirano shader programima.

Opisana proširenja su implementirana pomoænim razredima ForwardPass i PostEffectPass, koji enkapsuliraju detalje kao što su generiranje i prijenos tekstura izmeðu prolaza, itd.
