Edge-Sharpener: Recovering Sharp Features in Triangulations of non-adaptively re-meshed surfaces

13 years 9 months ago

Download www.ima.ge.cnr.it

3D scanners, iso-surface extraction procedures, and several recent geometric compression schemes sample surfaces of 3D shapes in a regular fashion, without any attempt to align th...

Incremental reconstruction of sharp edges on mesh surfaces

13 years 7 months ago

Download www2.acae.cuhk.edu.hk

Limited by the regular grids in computing, many modelling approaches (e.g., field-based methods) sample 3D shape insensitive to sharp features therefore exhibit aliasing errors, b...
