We present a pipeline for creating photo-realism of three-dimensional augmented objects, as well as a perceptual evaluating of the virtual scenes. Most of the content is rendered in real-time, while the augmented reality solution performs constant tracking of a marker. A setup utilizing different lighting conditions is created and artefacts of the video-feed are simulated. Different parameters affecting the realism are evaluated. These are screen space artefacts, shadows, lights, highlights and geometry. The results show that silhouettes of the shadows and the geometry and highlights on specular objects are important, as well as the simulation of noise, for creating a photorealistic augmentation. Furthermore, a side by side comparison is conducted to verify that it is possible to render a virtual object in realtime that is indistinguishable from a real object. The results showed that the virtual object is perceived as real under the best conditions. The design of the pipeline is important, to be able to virtualise the objects and the lights correctly.
