In realtime computer graphics, a texture atlas is a large image containing a collection, or "atlas", of sub-images, each of which is a texture for some part of a 2D or 3D object. The sub-textures can be rendered by modifying the texture coordinates of the object's uvmap on the atlas, essentially telling it which part of the image its texture is in. In an application where many small textures are used frequently, it is often more efficient to store the textures in a texture atlas which is treated as a single unit by the graphics hardware. In particular, because there are less rendering state changes...

M-DISC (Millennial Disc) is a write once optical disc technology introduced in 2009 and available as DVD and Blu-ray discs. == Overview == M-DISC's design is intended to provide greater archival media longevity. Millenniata claims that properly stored M-DISC DVD recordings will last 1000 years. While the exact properties of M-DISC are a trade secret, the patents protecting the M-DISC technology assert that the data layer is a "glassy carbon" and that the material is substantially inert to oxidation and has a melting point between 200° and 1000 °C. A stress test of the media was performed by the...
