Technical Field

Background
mipmap is a computer graphics imaging technique for achieving in two-dimensional replacements of three-dimensional imagesStereoscopic impressionAnd (4) effect. The mipmap technique is combined with the texture mapping technique, and a single texture map is represented in the form of multiple images at different resolutions according to the distance from a viewer, wherein the image with the largest size is placed in a prominent position in the front, and the relatively smaller image is backed to the background area. Each of the different size levels is defined as a mipmap level. The mipmap technique helps to avoid unwanted jagged edges (called jagged patterns) from appearing in the image, which may result from using a bit map image at different resolutions.
The mipmap function of the multiple detail layers of the texture is complex, and the related interfaces are numerous, so that the mipmap function is one of the important functions of the texture mapping. The processing of the mipmap of the multiple detail layers of the texture is related to the overall function of the texture map, and a complete set of verification method for the mipmap of the multiple detail layers is not available in the currently disclosed research.
