Example Embodiment
[0022] The accompanying drawings are only for illustrative purposes and cannot be understood as a limitation of the patent; in order to better illustrate this embodiment, some parts of the accompanying drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product;
[0023] For those skilled in the art, it is understandable that some well-known structures in the drawings and their descriptions may be omitted.
[0024] Such as figure 1 As shown, the fast rendering method of a large area network 3D noise map proposed by the present invention mainly includes three parts: storing the basic data of the large area in the form of map tiles, and loading the basic data of the corresponding area according to the current map browsing range , Use the interpolation method to fill the color inside the rectangular grid according to the noise value of the noise receiving point. The rendering process of the entire network 3D noise map is as follows:
