Problems solved by technology
[0003] At present, geological model sectioning is widely used in the fields of geology and civil engineering. Generally, geotechnical construction software or GIS software is used for modeling and sectioning, but there are many shortcomings: 1. The software is generally relatively large in size. Large, requires a certain hardware foundation, and cannot be used anytime and anywhere; 2. The operation is difficult, and it cannot be used by grassroots personnel; 3. There is no unified 3D geological modeling standard, and data interoperability between software is difficult; 4. Cost Higher, modeling and maintenance, as well as the training of grassroots personnel, etc., are not a small expenditure

Embodiment Construction
[0019] The implementation of the present invention will be further described below in conjunction with the accompanying drawings.
[0020] A 3D geological model sectioning method based on the web-side 3D drawing protocol, which mainly includes: the generation of virtual borehole data, the determination of the section plane, the retrieval of legends, the drawing of strata, and the preservation of results. The specific steps are as follows:
[0021] (1) Click any point on the surface of the geological model on the web page, draw a ray along the y direction on this point, generate a virtual borehole, calculate the intersection of this ray and all planes of the model and return the coordinates of each point, and obtain the borehole after deduplication Coordinates, sequence and height data of each layer, and return in the form of JSON array;
[0022] (2) According to the selected three or more drilling coordinates, use the built-in function of the drawing frame to generate a sectio...

And a model file in a text format can be downloaded in a Web page and can be viewed in other 3D modeling software.
Description
Technical field: [0001] The invention belongs to the interdisciplinary field of computer information technology and geology, and in particular relates to a 3D geological model cutting method based on a webpage-side 3D drawing protocol, which is suitable for assisting in the generation of 3D geological model sections in various geological modeling systems based on network platforms picture. Background technique: [0002] Three-dimensional geological modeling is to use computer technology to combine tools such as spatial information management, geological interpretation, spatial analysis and prediction, geo-statistics, entity content analysis, and graphic visualization in a three-dimensional environment for geological research. new technology. Through the 3D geological model, engineers can more intuitively understand the stratum structure and adverse geological information in the area, and assist them in making more accurate judgments and engineering designs. Geological mode...
