Rendering realistic outdoor scenes in realtimeapplications is a difficult task to accomplishsince the geometric complexity of the objects, andmost notably of trees, is too high for currenthardware to handle efficiently in large amounts.Our method generates trees with self-similarity, andlater exploits this property by heavily sharing prerenderedtextures of similar parts of the tree. Theintrinsic tree hierarchy of the trees, combined withtheir self-similarity, allows generation of multiplelevels of detail. Here we present the flow of theprocessing stage, from the collection of the requiredinput data until the export of the models in all theirlevels of detail as well as related and additionaldata.
