This paper considers how out-of-core visualization applies to terrain datasets, which are among the largest now presented for interactive visualization and can range to sizes of 20 GB and more. It is found that a combination of out-of-core visualization, which tends to focus on 3D data, and visual simulation, which places an emphasis on visual perception and real-time display of multiresolution data, results in interactive terrain visualization with significantly improved data access and quality of presentation. Further, the visual simulation approach provides qualities that are useful for general data, not just terrain. I. Introduction Interactive visualization of big data presents a significant challenge, but also offers the possibility of major rewards. Visualization is often the first step towards analysis and understanding. We must first "look at" the data before we can even know what to do next. Conversely, if we cannot even visualize the data, we cannot effectively explore and...
