In computer graphics, a texel, texture element, or texture pixel is the fundamental unit of a texture map. [1] Textures are represented by arrays of texels representing the texture space, just as other images are represented by arrays of pixels. Texels can also be described by image regions that are obtained through simple procedures such as ...
The resulting image may contain aliasing along the edges of transparent objects or edges within textures, although the image quality will be no worse than it would be without any anti-aliasing. [5] Translucent objects that are modelled using alpha-test textures will also be aliased due to alpha testing.
Alpha to coverage [1] [2] [3] is a multisampling computer graphics technique, that replaces alpha blending with a coverage mask.This achieves order-independent transparency for when anti-aliasing or semi-transparent textures are used.
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 ...
Example of texture splatting, except an additional alphamap is applied. In computer graphics, texture splatting is a method for combining different textures.It works by applying an alphamap (also called a "weightmap" or a "splat map") to the higher levels, thereby revealing the layers underneath where the alphamap is partially or completely transparent.
Intel's pixel synchronization [12] avoids the need to store all fragments, removing the unbounded memory requirement of many other OIT techniques. Weighted Blended Order-Independent Transparency replaced the over operator with a commutative approximation. Feeding depth information into the weight produces visually-acceptable occlusion.
Instead of each pixel either being transparent or not transparent, it can be set to 254 levels of partially transparent, allowing some of the background image to show through the foreground image. A major use of partial transparency is to produce "soft edges" in graphics so that they blend into their background. [1]
Alpha mapping is used when the given object's transparency is not consistent: when the transparency amount is not the same for the entire object and/or when the object is not entirely transparent. If the object has the same level of transparency everywhere, one can either use a solid-color alpha texture or an integer value.
