Summary: Fast Visualization of Plane-Like Structures in Voxel Data

ABSTRACT
We present a robust, noise-resistant criterion characterizing plane-
like skeletons in binary voxel objects. It is based on a distance map
and the geodesic distance along the object's boundary. A parameter
allows to control the noise sensitivity.
If needed, homotopy with the original object might be recon-
structed in a second step, using an improved distance ordered thin-
ning algorithm.
The skeleton is analyzed to create a geometric representation
for rendering. Plane-like parts are transformed into an triangulated
surface not enclosing a volume by a suitable triangulation scheme.
The resulting surfaces have lower triangle count than those created
with standard methods and tend to maintain the original geometry,
even after simplification with a high decimation rate. Our algo-
rithm allows to interactively render expressive images of complex
3D structures, emphasizing independently plane-like and rod-like
structures.
