What are Mipmaps? Texture Filtering in GLSL [Shaders Monthly #6]

In Episode #6 of Shaders Monthly, we talk about mipmaps and how they are used for texture filtering in computer graphics. Furthermore, we will demonstrate the implementation in GLSL. 1) Magnification Filter GSN Composer: https://www.gsn-lib.org/index.html#pr... C++: https://www.mathematik.uni-marburg.de...
