In computer graphics, mipmaps (also MIP maps) or pyramids [1] [2] [3] are pre-calculated, optimized sequences of images, each of which is a progressively lower resolution representation of the previous. The height and width of each image, or level, in the mipmap is a factor of two smaller than the previous level.
Geomipmapping or geometrical mipmapping is a real-time block-based terrain rendering algorithm developed by W.H. de Boer in 2000 that aims to reduce CPU processing time which is a common bottleneck in level of detail approaches to terrain rendering.
Since version 5, Unity has been offering its WebGL bundle compiled to JavaScript using a 2-stage language translator (C# to C++ and finally to JavaScript). [94] Unity was the default software development kit (SDK) used for Nintendo's Wii U video game console, with a free copy included by Nintendo with each Wii U developer license. Unity ...

Trilinear filtering is an extension of the bilinear texture filtering method, which also performs linear interpolation between mipmaps. [1] [2]Bilinear filtering has several weaknesses that make it an unattractive choice in many cases: using it on a full-detail texture when scaling to a very small size causes accuracy problems from missed texels, and compensating for this by using multiple ...

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 ...
