This paper describes displacement mapping technique that is used in 3D graphics to add detail on the object’s surface. There are various approaches for implementing it that suit different usages. Most common approaches are explained and shortcomings for each are listed. An adaptive view dependant tessellation algorithm is looked at more closely and some hardware related issues are also discusse...

2014 By means of optical microscopy, Kossel diagrams of chiral smectic phases are observed for the first time. Due to Bragg reflection, these diagrams occur in the focal plane of the microscope lens if the sample is illuminated with convergent monochromatic light. The Kossel diagram for the SmC* phase 2014 observed for the chiral compound CE3 (BDH) 2014 consists of a central ring corresponding ...

We investigate a connection between a renormalon ambiguity of heavy quark mass and the gluon condensate contribution into the quark dispersion law related with a virtuality, being a displacement of heavy quark from the perturbative mass-shell, which happens inside a hadron. Operator Product Expansion is among the most powerful tools in the heavy quark physics. In this respect it is usually appl...
