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 ...
The increase in storage space required for all of these mipmaps is a third of the original texture, because the sum of the areas 1/4 + 1/16 + 1/64 + 1/256 + ⋯ converges to 1/3. In the case of an RGB image with three channels stored as separate planes, the total mipmap can be visualized as fitting neatly into a square area twice as large as ...
Pixel shaders may also be applied in intermediate stages to any two-dimensional images—sprites or textures—in the pipeline, whereas vertex shaders always require a 3D scene. For instance, a pixel shader is the only kind of shader that can act as a postprocessor or filter for a video stream after it has been rasterized.

A multi-pack also known as multipack is packaging that combines or holds multiple items or smaller packages. Functions. Multi-packs can be used to:
The home page consists of a million pixels arranged in a 1000 × 1000 pixel grid; the image-based links on it were sold for $1 per pixel in 10 × 10 blocks. The purchasers of these pixel blocks provided tiny images to be displayed on them, a URL to which the images were linked, and a slogan to be displayed when hovering a cursor over the link ...
In solid-state electronics, silicon photomultipliers (SiPMs) are single-photon-sensitive devices based on pixels of single-photon avalanche diodes (SPADs) implemented on common silicon substrate. [1] The dimension of each single avalanche diode can vary from 10 to 100 micrometres , with a typical density of up to 1,000 pixels/mm 2 .
