Circuit board model file generation method, visualization method, module, device and medium

According to the model file generation method of the circuit board three-dimensional model provided by the invention, graphic data is converted into grid data, so that a drawing function of a system graphics card GPU can be directly called by virtue of graphic APIs such as openGL and webGL, a circuit board three-dimensional image is displayed on a display, and the visualization of the circuit board is realized. The circuit board three-dimensional model comprises a plurality of circuit board layers, and the model file generation method comprises the following steps: S1, obtaining a Gerber file, and analyzing the Gerber file according to a grammar rule of the Gerber file to obtain graphic data; wherein the graphic data comprises vertex coordinates, line segments and curves; s2, performing triangulation processing on the graphic data through a triangulation algorithm to obtain grid data of the plurality of circuit board layers; and S3, generating a model file of the circuit board three-dimensional model accordin
