| Abstract(in English) | This paper presents one part of our work on "hierarchical visualization". Here, we propose an efficient hierarchical structure for visualization of 3D volumetric data, where for instance, data compression techniques are embedded into the hierarchical structure. To implement the hierarchical structure we propose a partitioning algorithm for 3D volumetric data based on principal component analysis. With principal component analysis, the original 3D volumetric space can be divided into a number of 3D volumetric blocks such that each block contains similar data. Analyzing these specific blocks and taking advantage of the octree hierarchy, from the whole 3D volumetric data we can easily access only the part which is required to be displayed. The proposed partitioning algorithm is very useful to reduce the amount of rendering, which means that we need only to precisely render the block which is required to be displayed, and not the whole 3D volumetric dataset. |
