Search and retrieval of three-dimensional media will rapidly become a key issue in the upcoming panorama of multimedia content: 3D models are indeed expected to represent a huge amount of traffic and data stored in the Internet. This article proposes a nov...
 
Sharpen&Bend: Recovering Curved Sharp Edges in Triangle Meshes Produced by Feature-Insensitive Sampling
Found in: IEEE Transactions on Visualization and Computer Graphics
By Marco Attene, Bianca Falcidieno, Jarek Rossignac, Michela Spagnuolo
Issue Date:March 2005
pp. 181-192
Various acquisition, analysis, visualization, and compression approaches sample surfaces of 3D shapes in a uniform fashion without any attempt to align the samples with sharp edges or to adapt the sampling density to the surface curvature. Consequently, tr...
 
Analyzing Fuzzy Surface Modeling Using Load-Balanced Computation
Found in: Computing in Science and Engineering
By Andrea Clematis, Michela Spagnuolo
Issue Date:November 2001
pp. 74-81
There is a wide range of applications dealing with surfaces reconstructed from samples, which might benefit of tools for an explicit visualization of the model accuracy and data imprecision. Coupling fuzzy arithmetic with traditional geometric models is an...
 
Re-Meshing Techniques for Topological Analysis
