In the webgis system of the smart city business, some Chinese character descriptions are marked based on geographic coordinates, such as main building roofs, important facilities and the like. Most of the existing schemes in the industry are picture or flat style character labels, which can display Chinese character information but lack three-dimensional aesthetic feeling, and particularly under the condition that the webgis system has increasing requirements and use of three-dimensional objects, the pure three-dimensional Chinese character labels are required to be expanded to enhance the difference between the display of key areas, buildings, facilities and general two-dimensional flat style Chinese character labels. In the prior art, three-dimensional fonts cannot be displayed basically when the Chinese characters are displayed, so that the display effect is poor.
In order to solve the problems in the prior art, the present embodiment provides a three-dimensional chinese character construction method, as shown in fig. 1, the method includes the following steps:
and S100, acquiring a target Chinese character and determining vector information corresponding to the target Chinese character.
In specific implementation, the embodiment first selects mapbox. Both mapbox xgl. Js is an open source engine for maps in the webgis domain, used as a geographic information system. Js is a web-side general engine, and has rich community development components and accumulation, and a highly abstract graph drawing and rich interface expansion. By adopting the open source technology, the webgis system can be built in the shortest time, and the web server has considerable maturity and expansibility. The map is characterized in that the mapbacklog.js can independently render the threejs as a map layer in the map, the rich interfaces of the threejs support the development of a graphics bottom interface webgl, and the parallel rendering power of a GPU (graphics accelerator) can be called by using the pipeline programming of the webgl to calculate and simulate a vivid water simulation special effect, so that the webgis system built by the mapbacklog.js has the capability of directly communicating with the bottom layer, and the GPU (graphics accelerator) is used for rendering the efficient and stable special effect.
Then, the embodiment obtains the target Chinese character and records a Chinese character font library according to the target Chinese character; and then determining vector information corresponding to the target Chinese character according to the Chinese character font library. For example, when the target chinese character is "one", the vector information of "one" is obtained in the chinese character font library, including the initial coordinates and offset coordinates of "one", that is, the offset of all point locations on the description chinese character "one" with respect to the initial coordinates). The stored vector information is (0,0), (0.5,0) and (1,0) coordinates in the case of the Chinese character 'one', and the vector information describes three coordinate points forming the Chinese character 'one' because the vector information is simple and easy to see. The first coordinate (0,0) is shifted by 0 relative to the initial coordinate (the initial coordinate, i.e., the coordinate in which the Chinese character 'one' is placed in the webgis system, and possibly any spatial coordinate), i.e., the first coordinate is the initial coordinate, the second coordinate (0.5,0) is shifted by 0.5 units on the x-axis relative to the initial coordinate, and similarly the third coordinate is shifted by 1 unit on the x-axis.
And S200, generating a three-dimensional geometric body corresponding to the target Chinese character according to the vector information.
In specific implementation, the Chinese character font library is used as a vector information source, vector information corresponding to the target Chinese character is found out according to the input target Chinese character, and the vector information is transmitted to a three.js engine to prepare for next step of analysis and visualization of the vector information. Specifically, in this embodiment, the vector information is input into a three-dimensional engine, and the three-dimensional engine analyzes the vector information to obtain font information. And then generating a geometric body by using a graphical method according to the font information, and setting height information for the geometric body to obtain the three-dimensional geometric body. The font information includes: font size information, font thickness information, and coordinate information. Taking the chinese character "one" as an example, the present embodiment transmits the vector information of the chinese character "one" to the thread.js engine, so that the engine can analyze and generate a geometric body (Geometry) by using a graphical method, and then the geometric body is set to a certain height (thickness of the three-dimensional character) to obtain the three-dimensional chinese character entity character. The specific analysis process comprises the following steps of preparing necessary basic information such as initial coordinates, vector information of a target Chinese character, font size and font thickness information. And calculating the actual position coordinate of the target Chinese character 'one' in the space coordinate according to the vector information, the font size, the font thickness and the initial coordinate of the target Chinese character 'one'. Taking the specific vector information of the target Chinese character "one" as an example, the embodiment first solves the spatial coordinates corresponding to the initial coordinates, and then adds the three offset coordinates to the spatial coordinates corresponding to the initial coordinates to obtain the actual three vertex positions of the geometric solid of the Chinese character "one" in the spatial coordinates. According to the positions of the three vertexes, the vertex sequence of the Geometry is set to be 0-1-2, namely the sequence numbers of the vertexes in the vector information are set according to the sequence, and no matter complex Chinese characters or simple Chinese characters are set according to the rule. The specific algorithm is to clone one part of each vertex, add the Z component (initially 0) of the cloned vertex to the font thickness to obtain a new Z value, store the new coordinates, and obtain a new Geometry with two planes (one high and one low). In this embodiment, the new Geometry with two planes (one high and one low) is calculated from the vector information, font size, font thickness, and initial coordinates of the target Chinese character "one", and is the skeleton of the three-dimensional Chinese character label, so as to prepare for visualization.
And S300, carrying out visualization processing on the three-dimensional geometric solid to obtain the three-dimensional Chinese character so as to complete the construction of the three-dimensional Chinese character.
In specific implementation, taking a target Chinese character "one" as an example, the Geometry obtained at this time is a skeleton of the Chinese character "one", but cannot be seen, a thread. In addition, this embodiment preferably needs to ensure that the font label of the three-dimensional chinese character is perpendicular to the viewing angle of the camera, i.e. the front of the three-dimensional chinese character label always faces the screen no matter how the viewing angle rotates in webgis. Therefore, the present embodiment first monitors a camera rotation event, and determines a camera rotation angle according to the camera rotation event; and then setting the rotation angle of the three-dimensional Chinese character according to the rotation angle of the camera. And finally, controlling the font label of the three-dimensional Chinese character to rotate according to the rotation angle so as to enable the font label to face a screen. In particular, the present embodiment can take a real-time camera rotation angle using a map. The font label of the three-dimensional Chinese character is also a three-dimensional body, so that the three-dimensional Chinese character has a rotating function. The embodiment directly uses the mesh (rotatey) method to rotate the ground at a certain angle relative to the vertical direction of the ground. And only when the rotation angle of the webgis map camera is changed, the characters need to rotate, so that a rotation event from the camera is monitored by using map.on ('rotate', () { }), when the rotation event is monitored, the real-time camera rotation angle is taken by using a map.getleakage () method, and then the rotation angle is set for the three-dimensional Chinese character label by using a mesh.rotay () method, so that the three-dimensional Chinese character label can synchronously rotate along with the rotation angle of the webgis camera, and the font label of the three-dimensional Chinese character can be ensured to face the screen all the time. In the embodiment, the effect that the three-dimensional Chinese character tag follows the rotation angle of the camera is realized by monitoring the rotation event of the webgis system camera, monitoring the rotation of the camera, calculating the rotation angle of the text and realizing the rotation of the text, and the effect is shown in fig. 2.
