Ericsson Texture Compression (ETC) is a lossy texture compression technique developed in collaboration with Ericsson Research in early 2005. It was originally developed under the name iPACKMAN [ 1 ] and based on an earlier compression scheme called i PACKMAN .
Paint texture on The Sower with Setting Sun by Vincent van Gogh. In the visual arts, texture refers to the perceived surface quality of a work of art.It is an element found in both two-dimensional and three-dimensional designs, and it is characterized by its visual and physical properties.
Artificial texture example. Natural texture example. An image texture is the small-scale structure perceived on an image, based on the spatial arrangement of color or intensities. [1] It can be quantified by a set of metrics calculated in image processing. Image texture metrics give us information about the whole image or selected regions. [1]
Quickly rendered animations can be saved directly as video files, but for high-quality rendering, individual frames (which may be rendered by different computers in a cluster or render farm and may take hours or even days to render) are output as separate files and combined later into a video clip. [25] [15]: 1.5, 3.11, 8.11
Texture compression is a specialized form of image compression designed for storing texture maps in 3D computer graphics rendering systems. Unlike conventional image compression algorithms, texture compression algorithms are optimized for random access. Texture compression can be applied to reduce memory usage at runtime.
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 ...

An illustration of texture filtering methods showing a texture with trilinear mipmapping (left) and anisotropic texture filtering. In 3D computer graphics, anisotropic filtering (abbreviated AF) [1] [2] is a method of enhancing the image quality of textures.
