We present a novel approach for obtaining a complete and consistent 3D model representation from incomplete surface scans, using a database of 3D shapes to provide geometric priors
for rendering drilling and a low number for physical sim- ulation. We decouple the drilling from the physical simu- lation by allowing the representation of the drilling at
F or the classes of smooth surfaces studied the representation is unique. That is, the surface σ can be reconstructed from its two representing planar regions. ALL surfaces can
The height-field geometry representation employed in our system is a well known concept that, besides its use in com- pression (see above), spectral analysis [PG01], simplifica-
In order to overcome these limitations, we in- troduce a volumetric primitive, that we call split-voxel, which replaces blocks of N 3 voxels by one single voxel that is split by
In all images the resolution of the simulation grid is the same, but the hexahedral finite-element representation from which the stiffness matrices are assembled and the surface
The first part of our visualization stage provides the SDO data on a 3D sphere representation (Section 4.1) and focuses on the investigation of the 3D magnetic field from GONG
Second approach — tube mesh tunnel animation The second representation is derived from the previous one, which uses a set of spheres.. This representation, which we call a tube
