The texture minifying function is used whenever the level-of-detail function
used when sampling from the texture determines that the texture should be minified.
There are six defined minifying functions.
Two of them use either the nearest texture elements or a weighted average of multiple texture elements
to compute the texture value.
The other four use mipmaps.

As more texture elements are sampled in the minification process,
fewer aliasing artifacts will be apparent.
While the <code class="constant">GL_NEAREST</code> and <code class="constant">GL_LINEAR</code> minification functions can be
faster than the other four,
they sample only one or multiple texture elements to determine the texture value
of the pixel being rendered and can produce moire patterns
