Real-time rendering of realistic trees in mixed reality

Mixed reality applications put very high demands on both the visual realism and the rendering times of computer graphics elements that are to be perceived as part of the physical scene. This paper presents novel techniques to render photorealistic trees in real-time mixed reality. Animation of the tree branches leads to a realistic effect of the tree swaying in the wind. To enhance the effect of blending the tree into a video texture, we present three levels of real-time filtering of the tree and its shadow, which has a great impact on the perceived realism.
