Parallel coordinates and scatterplot matrices are widely used to visualize multidimensional data sets. But these visualization techniques are insufficient when the number of dimensions grows. To solve this problem, different approaches to preselect the best views or dimensions have been proposed in the last years. However, there are still several shortcomings to these methods. In this paper we present three new methods to explore multivariate data sets: a parallel coordinates matrix, in analogy to the wellknown scatterplot matrix, a classbased scatterplot matrix that aims at finding good projections for each class pair, and an importance aware algorithm to sort the dimensions of scatterplot and parallel coordinates matrices.
A variational approach is proposed for the unsupervised assessment of attribute variability of high-dimensional data given a differentiable similarity measure. The key question addressed is how much each data attribut...

The construction and processing of surface geometry can be done by connecting surface primitives to vertices, edges, and neighbors. The representation schemes of surface geometry are vertex-based, edge-based, and quad-edge-based. Catmull and Clark rule of subdivision includes three different rules to create new vertices in the refined control mesh, that are vertex, edge, and face subdivision rule. A new vertex can be created in the refined mesh as a convex combination of the vertices in the neighborhood of vertex, edge, and face in the control mesh. The first subdivision step has a quadrangle control mesh and number of vertices with valence unequal to four constant during refinement. The Charles Loop subdivision scheme is based on box spline and during a subdivision a triangle is divided into four triangles through vertex and edge subdivision rule.

Most laser scanners in engineering are extended versions of tactile measuring machines. These high precision devices are typically very expensive and hardware modifications are not possible without impairing the precision of the device. For these reasons we built our own laser-scanner system. It is based on a multi-camera reconstruction system developed for fast 3D face reconstructions. Based on this camera system, we developed a laser-scanner using GPU accelerated stereo-matching techniques and a hand-held line-laser probe. The resulting reconstruction is solely based on the known camera positions and parameters. Thus, it is not necessary to track the position and movement of the line-laser probe. This yields an inexpensive laser-scanner system where every hardware component can be modified individually for experiments and future extensions of the system.
