“…The first image (im1) for each scene has no global illumination whereas the second image (im2) has a global illumination generated from the sun and ambient occlusion. The lighting model within Second Life is generated using a Gaussian Bi-directional Reflectance Distribution Function (BRDF) [15]. The Fig.…”

“…Yet, in practice, the complexity can often be reduced for many materials, for example by observing that the spatial variations only affect certain components of the reflectance. A comprehensive overview of appearance modeling can be found in many excellent books [52,54] and surveys [124,223].…”

Description of the cover imageRendering of virtual furniture illuminated with spatially varying real world illumination captured in a physical environment at IKEA Communications AB.The virtual scene was modeled by Sören and Per Larsson. Physically based rendering of synthetic objects in real environmentsCopyright © 2015 Joel Kronander (unless otherwise noted) Division of Media and Information TechnologyDepartment of Science and Technology Campus Norrköping, Printed in Sweden by LiU-Tryck, Linköping, 2015 AbstractThis thesis presents methods for photorealistic rendering of virtual objects so that they can be seamlessly composited into images of the real world. To generate predictable and consistent results, we study physically based methods, which simulate how light propagates in a mathematical model of the augmented scene. This computationally challenging problem demands both efficient and accurate simulation of the light transport in the scene, as well as detailed modeling of the geometries, illumination conditions, and material properties. In this thesis, we discuss and formulate the challenges inherent in these steps and present several methods to make the process more efficient.In particular, the material contained in this thesis addresses four closely related areas: HDR imaging, IBL, reflectance modeling, and efficient rendering. The thesis presents a new, statistically motivated algorithm for HDR reconstruction from raw camera data combining demosaicing, denoising, and HDR fusion in a single processing operation. The thesis also presents practical and robust methods for rendering with spatially and temporally varying illumination conditions captured using omnidirectional HDR video. Furthermore, two new parametric BRDF models are proposed for surfaces exhibiting wide angle gloss. Finally, the thesis also presents a physically based light transport algorithm based on Markov Chain Monte Carlo methods that allows approximations to be used in place of exact quantities, while still converging to the exact result. As illustrated in the thesis, the proposed algorithm enables efficient rendering of scenes with glossy transfer and heterogenous participating media.v Populärvetenskaplig SammanfattningEn av de största utmaningarna inom datorgrafik är att syntetisera, eller rendera, fotorealistiska bilder. Fotorealistisk rendering används idag inom många tillämpningsområden såsom specialeffekter i film, datorspel, produktvisualisering och virtuell verklighet. I många praktiska tillämpningar av fotorealistisk rendering är det viktigt att kunna placera in virtuella objekt i fotografier, så att de virtuella objekten ser verkliga ut. IKEA-katalogen, till exempel, produceras i många olika versioner för att passa olika länder och regioner. Grunden till de flesta bilderna i katalogen är oftast densamma, men symboler och standardmått på möbler varierar ofta för olika versioner av katalogen. Istället för att fotografera varje version separat kan man använda ett grundfotografi och lägga in olika virtuella objekt såsom möbler...
