The invention discloses a vector data processing method and device based on a virtual engine and a medium, and the method comprises the steps: compiling a GDAL library in the virtual engine, and calling the GDAL library to read coordinate data of vector data; drawing the coordinate data into a contour line in real time by using the compiled virtual engine; selecting coordinate points to be edited in the contour line; obtaining target data, and editing the to-be-edited coordinate point according to the target data; and generating a graph of the edited coordinate data in real time by using the compiled virtual engine. The GDAL library is compiled in the virtual engine, reading of quantity data is completed, the contour line is drawn in real time through the compiled virtual engine, the contour line is edited, and processing such as reading and editing of vector data can be efficiently and flexibly completed in the vector data running process. After a spline curve is generated through a spline component, vector data editing can be rapidly and efficiently achieved in an editing mode through a level editor.
Description
technical field [0001] The present invention relates to the technical field of computer graphics, in particular to a virtual engine-based vector data processing method, device and medium. Background technique [0002] Vector data is an important geographic information data. It is based on the spatial information and attribute information of geographic entities. It expresses map graphics in the form of spatial discrete points. By recording coordinates, it accurately expresses point, line, and area geographic entities. The spatial expression and spatial analysis of entities mostly rely on vector data. [0003] Unreal Engine (Unreal Engine) is one of the current mainstream game engines. Thanks to the powerful 3D creation capabilities of Unreal Engine, building a digital twin platform with Unreal Engine has become an important research direction. [0004] With the continuous advancement of the application of Unreal Engine in the digital twin platform, directly loading and editi...
