Freeform Shape Representations for Efficient Geometry Processing
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
The most important concepts for the handling and storage of freeform shapes in geometry processing applications are parametric representations and volumetric representations. Both have their specific advantages and drawbacks. ...
Sub-Voxel Topology Control for Level-Set Surfaces
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
Active contour models are an efficient, accurate, and robust tool for the segmentation of 2D and 3D image data.In particular, geometric deformable models (GDM) that represent an active contour as the level set of an ...
Multiresolution Surface Representation Based on Displacement Volumes
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We propose a new representation for multiresolution models which uses volume elements enclosed between thedifferent resolution levels to encode the detail information. Keeping these displacement volumes locally constantduring ...
