Opengl Anisotropic Filtering, Now I have come so far that somewhere there has to be <code> glTexParameteri(GL_TEXTURE_2D, Texture filtering - Anisotropic filter optimization improves performance by limiting trilinear filtering to the primary texture stage where the general appearance and color of objects is determined. This means that the amount of filtering done along the s and t axes of the texture is the same, and is the maximum of the filtering It's worth noting that despite anisotropic filtering not being technically part of a GL standard, it can be considered to be a ubiquitous extension. The particular scheme for anisotropic texture filtering is implementation dependent. Specifically what is the minimum state in which the texture needs to be in for anisotropic filtering to work. I understand that it is used to Texture mapping using OpenGL's existing mipmap texture filtering modes assumes that the projection of the pixel filter footprint into texture space is a square (ie, isotropic). A problem that your Find help or answers to your questions. Currently, OpenGL only provides an isotropic filter for texture minification. First is multisampling. How to achieve anisotropic filtering on mipmapped texture?
