Animating Volumetric Models

Nikhil Gagvani, Deborah Silver
2001 Graphical Models  
The animated skeleton is used for reconstruction, which essentially recreates a deformed volume around the deformed skeleton.  ...  The technique gives the animator the ability to treat volumes as if they were standard polygonal models and to use all of the standard animation/motion capture tools on volumetric data.  ...  The skeleton-tree can also be used as a general data structure for accessing the volume, for example, to speed up rendering.  ...

The Fractal Geometry of Bronchial Trees Differ by Strain in Mice

Robb William Glenny, Melissa A. Krueger, Christian Bauer, Reinhard R. Beichel
2020 Journal of applied physiology  
Fractal biological structures are pervasive throughout the plant and animal kingdoms with the mammalian lung being a quintessential example.  ...  While the blood flow pattern generated by these fractal trees has been shown to be genetically determined, the geometry of the trees has not.  ...  We elected to use the skeletonized representation of the bronchial tree to focus primarily on the network topology rather than the volumes occupied by the tree.  ...

Interactive 3D Analysis of Blood Vessel Trees and Collateral Vessel Volumes in Magnetic Resonance Angiograms in the Mouse Ischemic Hindlimb Model

Peter C. Marks
2013 Open Medical Imaging Journal  
Using MRAs of the mouse hindlimb ischemia model, we demonstrate quick and reproducible blood vessel volume calculations with 95 -98% accuracy.  ...  The quantitative analysis of blood vessel volumes from magnetic resonance angiograms (MRA) or µCT images is difficult and time-consuming.  ...  ACKNOWLEDGEMENTS This work was supported in part by the Mouse Transgenic and In Vivo Imaging Core and the Administrative Core of Facility NIH grant P30GM103392 (R.E.  ...

Shape-based volumetric collision detection

Nikhil Gagvani, Deborah Silver
2000 Proceedings of the 2000 IEEE symposium on Volume visualization - VVS '00  
Since our method is based on the shape of the object, the hierarchical spheres are determined for the first frame and can then animate along with the volumetric object.  ...  Because of the tighter fit, we are able to use fewer spheres for collision testing at each level, thus decreasing computation time.  ...  Acknowledgments We gratefully acknowledge the support of Sarnoff Corporation for part of this work. Kundan Sen at the Rutgers Visualization Lab produced the animations of the Visible Man.  ...

3D skeletonization using an enhanced voxel tree

Xing-Dong Yang, Irene Cheng
2006 ACM SIGGRAPH 2006 Research posters on - SIGGRAPH '06  
These techniques either focus on a volume, e.g. medical DICOM data, or mesh data. Our skeletonization method using voxels is stable and can be used for both mesh and volume data.  ...  INTRODUCTION Although mesh mapped with texture is observed by viewers, skeleton is often used as a compact and simplified form to represent a complex 3D object for backend processing, e.g. animation, similarity  ...
