Photorealistic Rendering of Mixed Reality Scenes
(The Eurographics Association and John Wiley & Sons Ltd., 2015) Kronander, Joel; Banterle, Francesco; Gardner, Andrew; Miandji, Ehsan; Unger, Jonas; K. Hormann and O. Staadt
Photo-realistic rendering of virtual objects into real scenes is one of the most important research prob- lems in computer graphics. Methods for capture and rendering of mixed reality scenes are driven by a large number of applications, ranging from augmented reality to visual e ects and product visualization. Recent developments in computer graphics, computer vision, and imaging technology have enabled a wide range of new mixed reality techniques including methods for advanced image based lighting, cap- turing spatially varying lighting conditions, and algorithms for seamlessly rendering virtual objects directly into photographs without explicit measurements of the scene lighting. This report gives an overview of the state-of-the-art in this eld, and presents a categorization and comparison of current methods. Our in-depth survey provides a tool for understanding the advantages and disadvantages of each method, and gives an overview of which technique is best suited to a speci c problem.
