Adaptive scalable texture compression (ASTC) is a lossy block-based texture compression algorithm developed by Jørn Nystad et al. of ARM Ltd. and AMD. [1]Full details of ASTC were first presented publicly at the High Performance Graphics 2012 conference, in a paper by Olson et al. entitled "Adaptive Scalable Texture Compression".
All convert a 4×4 block of pixels to a 64-bit or 128-bit quantity, resulting in compression ratios of 6:1 with 24-bit RGB input data or 4:1 with 32-bit RGBA input data. S3TC is a lossy compression algorithm, resulting in image quality degradation, an effect which is minimized by the ability to increase texture resolutions while maintaining the ...
Given the above, most texture compression algorithms involve some form of fixed-rate lossy vector quantization of small fixed-size blocks of pixels into small fixed-size blocks of coding bits, sometimes with additional extra pre-processing and post-processing steps. Block Truncation Coding is a very simple example of this family of algorithms.
The popularity of Minecraft mods has been credited for helping Minecraft become one of the best-selling video games of all time. The first Minecraft mods worked by decompiling and modifying the Java source code of the game. The original version of the game, now called Minecraft: Java Edition, is still modded this way, but with more advanced tools.
A cloth with a nap. Primarily, nap is the raised (fuzzy) surface on certain kinds of cloth, such as velvet or moleskin.Nap can refer additionally to other surfaces that look like the surface of a napped cloth, such as the surface of a felt or beaver hat.
Felt is used extensively in pianos; for example, piano hammers are made of wool felt around a wooden core. The density and springiness of the felt is a major part of what creates a piano's tone. [ 41 ] [ 42 ] As the felt becomes grooved and "packed" with use and age, the tone suffers. [ 43 ]
Lustrous silk yarns. In textiles, lustre or luster is a physical property that makes them appear bright, glossy, and shiny. The amount of light reflected from the surface of a fiber is referred to as its luster.
Worsted is a yarn and cloth usually made from wool. The yarn is well twisted and spun of long staple wool (though nowadays also medium and short fibers are used). The wool is combed so that the fibers lie parallel. woven fabric A woven fabric is a cloth formed by weaving. It only stretches in the bias directions (between the warp and weft ...
