During the texture mapping process for any arbitrary 3D surface, a texture lookup takes place to find out where on the texture each pixel center falls. For texture-mapped polygonal surfaces composed of triangles typical of most surfaces in 3D games and movies, every pixel (or subordinate pixel sample) of that surface will be associated with some triangle(s) and a set of barycentric coordinates ...
Like all types of glass, it is a state of matter intermediate between the closely packed, highly ordered array of a crystal and the highly disordered array of liquid. [1] Volcanic glass may refer to the interstitial material, or matrix , in an aphanitic (fine-grained) volcanic rock , or to any of several types of vitreous igneous rocks .
A glass building facade. Glass is an amorphous (non-crystalline) solid.Because it is often transparent and chemically inert, glass has found widespread practical, technological, and decorative use in window panes, tableware, and optics.
"Beach glass" comes from fresh water and is often less frosted in appearance than sea glass. Sea glass takes 20–40 years, and sometimes as much as 100–200 years, to acquire its characteristic texture and shape. [2] It is also colloquially referred to as drift glass from the longshore drift process that forms the smooth edges.
K9 glass, sometimes referred to as K9 crystal, is a variety of optical borosilicate crown glass. The letter "K" is a reference to the German word for "crown" (Krone) and the number 9 refers to the lead oxide content of the glass (9%). K9 glass has high optical clarity, and is used in many contexts requiring this characteristic.
A glasspack is a type of automobile muffler in which the exhaust gas passes straight through the center of the muffler. The basic design consists of one smaller tube centered inside a larger outer tube that is enlarged or swollen in the middle.
