Abstract
Properly accommodating virtual 3D objects into real world scenes is an essential challenge in creating immersive experiences in real-time mobile augmented reality (AR) applications. Realistic shading of virtual objects is important in fusing rendered 3D objects into real scenes. Image-based lighting (IBL) methods are widely used in real-time computer graphics applications to represent the surrounding lighting conditions and to utilize this information in rendering. IBL methods typically use pre-processed high dynamic range (HDR) environment maps as input. These HDR maps represent the high dynamic range of light surrounding the shaded virtual objects. Capturing HDR environment maps has been researched in real scenes, but the existing methods apply restrictions that are not acceptable for many mobile AR applications. Furhermore, no research exists that describes if and how a complete au
