  2. Texture synthesis - Wikipedia

    en.wikipedia.org/wiki/Texture_synthesis

    Texture synthesis is the process of algorithmically constructing a large digital image from a small digital sample image by taking advantage of its structural content. It is an object of research in computer graphics and is used in many fields, amongst others digital image editing, 3D computer graphics and post-production of films.

  3. Image texture - Wikipedia

    en.wikipedia.org/wiki/Image_texture

    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]

  4. Alpha compositing - Wikipedia

    en.wikipedia.org/wiki/Alpha_compositing

    In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. [1] It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite.

  5. Procedural texture - Wikipedia

    en.wikipedia.org/wiki/Procedural_texture

    In computer graphics, a procedural texture [1] is a texture created using a mathematical description (i.e. an algorithm) rather than directly stored data. The advantage of this approach is low storage cost, unlimited texture resolution and easy texture mapping . [ 2 ]

  6. Mipmap - Wikipedia

    en.wikipedia.org/wiki/Mipmap

    A high-resolution mipmap image is used for high-density samples, such as for objects close to the camera; lower-resolution images are used as the object appears farther away. This is a more efficient way of downscaling a texture than sampling all texels in the original texture that would contribute to a screen pixel ; it is faster to take a ...

  7. Texel (graphics) - Wikipedia

    en.wikipedia.org/wiki/Texel_(graphics)

    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 ...

  8. Texture filtering - Wikipedia

    en.wikipedia.org/wiki/Texture_filtering

    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 ...

  9. Anisotropic filtering - Wikipedia

    en.wikipedia.org/wiki/Anisotropic_filtering

    With mipmap anisotropic filtering, a texture of resolution 256px × 256px would not only be downsampled to 128px × 128px, but also to other non-square resolutions, such as 256px × 128px and 32px × 128px. These anisotropically downsampled images can be probed when the texture-mapped image frequency is different for each texture axis. Then ...
