Abstract

U ovom radu su predstavljene neke od poboljšanih varijanti algoritma mape sjene. Obrađeni algoritmi se mogu podijeliti na filtrirane mape sjena i kaskadne mape sjena koji su predstavnik skupine particijskih algoritama. U skupini filtriranih mapa sjena se razlikuju algoritmi bez predfiltriranja s fiksnom i s varijabilnom veličinom filtra te algoritmi s predfiltriranjem. Opisana je teorijska pozadina te nedostatci i moguća rješenja svakog algoritma. Napravljena je implementacija koja omogućuje usporedbu svih obrađenih algoritama i analizu utjecaja raznih parametara na kvalitetu sjene.

Abstract (english)

In this paper, some of the improved variants of the shadow map algorithm are presented. Those algorithms can be divided into filtered shadow maps and cascaded shadow maps which is representative of z-partition algorithms. In the group of filtered shadow maps, algorithms without prefiltering with a fixed and with a variable filter size and algorithms with prefiltering are distinguished. The theoretical background is described, as well as the shortcomings and possible solutions of each algorithm. An implementation has been made that allows comparison of all processed algorithms and the analysis of the influence of various parameters on the shadow quality.
