Hierarchical Data Structures for Interactive Volume Visualization
نویسندگان
چکیده
In order to interactively investigate large scale D data sets we propose an improved hierarchical data structure for structured grids and an original hierarchical data struc ture for unstructured grids These multi tiered implementations allow the user to interactively control both the local and global density of the mesh Therefore the user can interactively re ne areas of interest and decimate peripheral regions By controlling the density of the mesh throughout the volume the user controls where computational cycles are spent and gains a deeper insight into the geometric structure of the mesh

Hierarchical Volume Visualization of Brain Anatomy
Scientific data-sets often come with an inherent hierarchical structure such as functional substructures within organs. In this work we propose a new visualization approach for volume data which is augmented by the explicit representation of hierarchically structured data. The volumetric structures are organized in an interactive hierarchy view. Seamless zooming between data visualization, with...
متن کاملInteractive illustrative visualization of hierarchical volume data
In scientific visualization the underlying data often has an inherent abstract and hierarchical structure. Therefore, the same dataset can simultaneously be studied with respect to its characteristics in the three-dimensional space and in the hierarchy space. Often both characteristics are equally important to convey. For such scenarios we explore the combination of hierarchy visualization and ...
متن کاملA fast hierarchical traversal strategy for multimodal visualization
In the last years there is a growing demand of multimodal medical rendering systems able to visualize simultaneously data coming from different sources. This paper addresses the Direct Volume Rendering (DVR) of aligned multimodal data in medical applications. Specifically, it proposes a hierarchical representation of the multimodal data set based on the construction of a Fusion Decision Tree (F...
متن کاملHierarchical Splatting of Scattered Data
Numerical particle simulations and astronomical observations create huge data sets containing uncorrelated 3D points of varying size. These data sets cannot be visualized interactively by simply rendering millions of colored points for each frame. Therefore, in many visualization applications a scalar density corresponding to the point distribution is resampled on a regular grid for direct volu...
متن کاملFeature-based Volume Rendering of Simulation Data
In this paper we present a framework for interactive volume rendering of high-dimensional flow simulation data. Our approach combines information visualization, flow visualization, as well as volume visualization techniques for volumetric flow visualization. Interactive feature specification by use of multiple linked views and composite non-binary brushes enables selection and multiple definiti...
