Remeshing

Remeshing is another application of volumetric representation. Given a polygonal mesh (figure (c)), we first convert it into a volume representation by sampling its distance field and normals on a fine uniform grid. Applying CMS algorithm to this volume gives a remeshed version of the original mesh (Figure (d)), which has a better tessellation than the input. For a better comparison, Figure (a,b) show the close-up views of (c,d). Figure (e,f) show the remeshing results for different values of threshold. This value affects the quality of remeshing.
