This paper presented a novel hybrid rendering system for forest scene that solved the classic problem of degraded quality of image-based representations at close distances by building an impostor rendering system on top of a full,geometry-based,forest rendering system.This enabled almost imperceptible switching between the two representations.By using a novel texture atlas based impostor algorithm,achieved a considerable performance gain.This system was embedded in an real world natural scene simulation application for testing purpose.The results demonstrate this system capable of rendering dense forest with the visual realism of a high-resolution geometry rendering system,but only at a fraction of the rendering cost.
