2b2t ( 2builders2tools) is a Minecraft server founded in December 2010. 2b2t has essentially no rules and players are not permanently banned, known within Minecraft as an " anarchy server". [2] As a result, players commonly engage in the destruction of other players' and groups creations, colloquially called "griefing", as well as hacking using ...
A diamond plate texture rendered close-up using physically based rendering principles. Microfacet abrasions cover the material, giving it a rough, realistic look even though the material is a metal. Specular highlights are high and realistically modeled at the appropriate edge of the tread using a normal map.
X-ray optics. X-ray optics is the branch of optics that manipulates X-rays instead of visible light. It deals with focusing and other ways of manipulating the X-ray beams for research techniques such as X-ray diffraction, X-ray crystallography, X-ray fluorescence, small-angle X-ray scattering, X-ray microscopy, X-ray phase-contrast imaging, and ...
X-ray lithography is a process used in semiconductor device fabrication industry to selectively remove parts of a thin film of photoresist. It uses X-rays to transfer a geometric pattern from a mask to a light-sensitive chemical photoresist , or simply "resist," on the substrate to reach extremely small topological size of a feature.
In radiography, X-ray microtomography uses X-rays to create cross-sections of a physical object that can be used to recreate a virtual model ( 3D model) without destroying the original object. It is similar to tomography and X-ray computed tomography. The prefix micro- (symbol: μ) is used to indicate that the pixel sizes of the cross-sections ...
X-rays (or rarely, X-radiation) are a form of high-energy electromagnetic radiation. In many languages, it is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it in 1895 [1] and named it X-radiation to signify an unknown type of radiation.
The observed X-ray background is thought to result from, at the "soft" end (below 0.3 keV), galactic X-ray emission, the "galactic" X-ray background, and, at the "hard" end (above 0.3keV), from a combination of many unresolved X-ray sources outside of the Milky Way, the "cosmic" X-ray background (CXB). The galactic X-ray background is produced ...
X-ray specs. X-ray specs or X-ray glasses are an American novelty item, purported to allow users to see through or into solid objects. In reality, the spectacles merely create an optical illusion; no X-rays are involved. The current paper version is sold under the name "X-Ray Spex"; a similar product is sold under the name "X-Ray Gogs".
