Investigation of light pipe simulation algorithms

Anders Schou

AbstractThe subject of this thesis is to test whether progressive photon mapping and/or stochastic progressive photon mapping can be used in daylight simulations of interior of a room with a light pipe introducing natural lighting into the room. The algorithms tested (progressive photon mapping and stochastic progressive photon mapping), are both multi-pass algorithms that solves global illumination in a robust way with bounded memory consumption, while converging to the correct solution. To simulate the sky the CIE [DK02] standard sky patterns have been used which returns the luminance of an arbitrary sky element. In the tests a model of the VELUX TRM 010 Sun tunnel was used. The results obtained from progressive photon mapping and stochastic progressive photon mapping have been tested against the analytical solution HOLIGILM [KDK08], and an implementation of path tracing.
