Efficient Out-of-Core Terrain RenderingPerformance- Limited by triangle throughput- Achieves ~20fps on Intel 4000- Recent NVIDIA GPUs 200+ fps- Degrades “graceful”- Coarse levels fetched first- Due to compression, can streamacross “narrow” bandwidths- e.g., 30MB/sec USB drivesVector data overlay (Utah data set)King Abdullah University of Science and Technology28
