Surface Reconstruction with Constrained Sculpting Surface Reconstruction with Constrained Sculpting Surface Reconstruction with Constrained Sculpting

The problem of three-dimensional surface reconstruction from a set of unorganized set of points sampled from the surface of an object is important in many applications, such as computer vision, computer-aided design and solid modeling. In recent years several algorithms have been presented for surface reconstruction with provable guarantee on the closeness of the approximation. This thesis pres...

Surface Reconstruction with a Fractional Hole : 5 p 5 p R 26 : 6 LaAlO 3 ( 001 )

The structure of the 5 p 5 p R26:6 reconstruction of LaAlO3 (001) has been determined using transmission electron diffraction combined with direct methods. It has a lanthanum oxide termination with one lanthanum vacancy per surface unit cell. Density functional calculations indicate that charge compensation occurs by a fractional number of highly delocalized holes, and that the surface contains...

Surface Reconstruction

We describe the problem of surface reconstruction from the point clouds which is applied in many scientific and engineering applications. Our aim is to obtain a visualization of data from 3D scanning and document the real objects digitally. Digital documentation brings the possibility to manipulate with surfaces in mathematical and modelling computer software. It can help with reconstruction an...
