Octreemizer: A Hierarchical Approach for Interactive Roaming Through Very Large Volumes [article]

John Plate, Michael Tirtasana, Rhadamés Carmona, Bernd Fröhlich
2002 EUROVIS 2005: Eurographics / IEEE VGTC Symposium on Visualization  
We have developed a hierarchical paging scheme for handling very large volumetric data sets at interactive frame rates.  ...  Our approach makes it feasible to deal with these volumes on desktop machines.  ...  We thank the members of the consortium for their valuable feedback during our meetings.  ...

Occlusion Culling for Sub-Surface Models in Geo-Scientific Applications [article]

John Plate, Anselm Grundhoefer, Benjamin Schmidt, Und Bernd Froehlich
2004 EUROVIS 2005: Eurographics / IEEE VGTC Symposium on Visualization  
For each tile and for the polygonal objects, the first rendering pass computes a z-buffer image using the low resolution tiles, the polygonal objects and the non-transparent volume objects.  ...  Our non-conservative approach does not require front to back sorting and it works for dynamic scenes.  ...  Octreemizer allows roaming through very large volumes using a hierarchical two-level paging approach, which pages volume bricks from the hard disk into main memory and from main memory into texture memory  ...

A Flexible Multi-Volume Shader Framework for Arbitrarily Intersecting Multi-Resolution Datasets

J. Plate, T. Holtkaemper, B. Froehlich
2007 IEEE Transactions on Visualization and Computer Graphics  
Our current implementation uses slice-based volume rendering and allows interactive roaming through multiple intersecting multi-gigabyte volumes.  ...  Each volume is represented by a multi-resolution octree-based structure and we use out-of-core techniques to support extremely large volumes.  ...  Our work is based on Octreemizer [7] , a 3D-texture-based approach for interactive visualization of very large volumetric datasets.  ...
