Problems & solutions
Jaroslav Křivánek · 2008
This part of the course summarizes the common problems encountered when implementing irradiance caching. For each of the problems we describe one or more possible solutions to alleviate it. It should be stressed that this part describes the solutions used in my own implementation but slightly different solutions may be used in other implementations. Various tricks used at PDI/Dreamworks are described by Eric Tabellion.
