Non-Periodic Corner Tilingsin Computer Graphics
(Schlömer, 2012-11-16)Rendering computer-generated images is both memory and runtime intensive.This is particularly true in realtime computer graphics where large amounts ofcontent have to be produced very quickly and from limited data. ... -
Non-Uniform Deformable Volumetric Objects for Medical Organ Segmentation and Registration
(Erdt, 2012-06-13)In medical imaging, large amounts of data are created during each patient examination, especially using 3-dimensional image acquisition techniques such as Computed Tomography. This data becomes more and more difficult to ... -
Numerical and variational aspects of mesh parameterization and editing
(Zayer, Rhaleb, 2007-09-17)A surface parameterization is a smooth one-to-one mapping between the surface and a parametric domain. Typically, surfaces with disk topology are mapped onto the plane and genus-zero surfaces onto the sphere. As any ... -
NURBS und Unterteilungsflächen: Adaptive Visualisierung von Unterteilungsflächen und ihre Erweiterung auf nicht-uniforme Flächen
