Abstract [en]

Augmented Reality (AR), the combination of real and virtual worlds, is a growing area in computer graphics. Until now, most of the focus has been on placing synthetic objects in the right position with regards to the real world, and to explor the possibilities of human interaction within the two worlds. This thesis presents the fact that virtual objects must not only be placed correctly but also lit truthfully in order to achieve a good degree of immersion. Conventional rendering techniques such as ray-tracing and radiosity requires intensive calculations and preparations for satisfying results. Hence, they are less usable for AR that demands calculations to perform in real time. We present a framework for rendering the synthetic objects using captured lighting conditions in real time. We use improved standard techniques for shadowing and lighting that we adapt for the use in a dynamic AR system as well as recent techniques of image based lighting.
