This is the second of two reports describing my work with the proposed method, called Geometrically Derived Image Based Lighting (GDIBL). The method introduce a technique to reconstruct spatially variant lighting conditions for rendering synthetic objects in computer graphics. This is achieved by referencing multiple light probes through a rough geometric representation of the sampled scene. The GDIBL method was successfully validated through the implementation and demonstration of it's effect on a synthetically rendered scene.

Dette er den anden af to rapporter der beskriver arbejdet med metoden Geometrisk Afledt Billed-baseret Lyssætning (eng. GDIBL). Metoden introducerer en teknik til at rekonstruere rumligt varierende lys til brug for rendering af syntetiske objekter i computer grafik. Dette opnåes ved at aflede lysinformation fra multible lys-optagelser gennem reference af en grov geometrisk representation af den givne scene. GDIBL metoden blev valideret gennem implementering og demonstration af dens effekt på en syntetisk scene.
