We introduce <i>hybrid billboard clouds</i>, a part-mesh, part-billboard representation used to simplify 3D models in the context of real-time rendering. Our hybrid generation method produces simplified models with improved appearance when compared to models generated by either image-based or mesh simplification alone.
In recent years the relative speed difference between CPUs and main-memory has become so great that many applications , including database management systems, spend much of their time waiting for data to be delivered from main-memory. In particular, B +-trees have been shown to utilize cache memory poorly, triggering the development of many cache-conscious(More)
