Slicing is a very useful dimension reduction tool that removes or reduces occlusion problems in visualizing 3D/4D volumetric data sets and that enables fast visual exploration of such data sets. We show that the data layouts based on typical space-filling curves are not optimal for the out-of-core slicing queries and present a novel component-based data layout scheme for a specialized problem domain, in which it is only required to provide fast slicing at every k-th value, for any k gt; 1. Our component-based data layout scheme provides much faster processing time for any axis-aligned slicing direction at every k-th value, k gt; 1, requiring less cache memory size and without any replication of data. In addition, the data layout can be generalized to any high dimension.}, keywords = {axis-aligned, cache, curves;very, data, data;data, databases;, handling;query, large, layout;data, memory, multidimensional, processing;very, queries;space-filling, size;component-based, slicing, slicing;out-of-core, volumetric}, doi = {10.1109/SSDBM.2007.7}, author = {Kim,Jusub and JaJa, Joseph F.} }
