Texture filtering

In computer graphics, a mipmap (mip being an acronym of the Latin phrase multum in parvo, meaning "much in little") is a pre-calculated, optimized sequence of images, each of which has an image resolution which is a factor of two smaller than the previous. Their use is known as mipmapping.
