The electronic device may Call a Web graphics library interface, such as a Draw Call command, for each VBO to render and display the objects in the target engineering drawing, that is, the electronic device may render and display a plurality of objects by calling the Draw Call command once. Therefore, the Call times to the Draw Call can be reduced, the rendering efficiency is improved, and the display performance is improved.
The application scenario of the engineering drawing display method in the embodiment of the application is described below.
As shown in fig. 3, the application scenario may include a server 310 and an electronic device 320, where the electronic device 320 may include a smart Phone (such as an Android Phone, an iOS Phone, a Windows Phone, etc.), a tablet computer, a palmtop computer, a notebook computer, a video matrix, a monitoring platform, a mobile internet device (MID, mobile Internet Devices), or a wearable device, etc., which are merely examples, but not limited to the above-mentioned apparatus. The electronic device 320 may access the server 310 through the internet or a local area network, a drawing display client may be built in the electronic device 320, and the electronic device 320 may perform data interaction with the server 310 through the drawing display client.
In some embodiments, server 310 may be a host of a personal computer PC and electronic device 320 may be a display device connected to the personal computer PC.
Specifically, the server 310 may obtain the class and coordinate point data of the object in the target engineering drawing, combine the coordinate point data of the object in the same class in the target engineering drawing to obtain the target object data, store the target object data in a vertex buffer object VBO, and when the target engineering drawing needs to be displayed, the electronic device 320 may obtain the target object data stored in the vertex buffer object VBO from the server 310, then render the coordinate point data, and display the object in the target engineering drawing. That is, the server may classify the objects in the target engineering drawing in advance, each class of objects is merged and then stored in a VBO correspondingly, and then the electronic device may Call a Web graphics library interface, such as a Draw Call command, for each VBO to perform rendering, so that the number of times of Call to Draw Call is reduced, rendering efficiency is improved, and display performance is improved.
The Web graphics library (Web Graphics Library, webGL) is a JavaScript API that can render high-performance interactive 3D and 2D graphics in any compatible Web browser without the use of plug-ins. WebGL does this by introducing an API that is very consistent with OpenGL ES 2.0, which can be used in the HTML5< canvas > element. This consistency allows the API to take advantage of the hardware graphics provided by the user device.
An engineering drawing display method provided in an embodiment of the present application is described below with reference to fig. 4.
Fig. 4 is a schematic flow chart of an engineering drawing display method provided in an embodiment of the present application, and is developed below:
stage one (S401-S408): original object display
S401, the server acquires category and coordinate point data of a first object and a second object in a target engineering drawing.
The first object and the second object in the target engineering drawing may be graphics in the target engineering drawing. Each object has a corresponding category, which may include points, lines, faces, text, etc. The coordinate point data may include vertex data, which may be used to represent objects in the target engineering drawing.
The target engineering drawing at least comprises a first object and a second object. The first object and the second object may be objects of the same class.
And S402, when the categories of the first object and the second object are the same, the server merges the coordinate point data of the first object and the coordinate point data of the second object into first target object data.
Specifically, when the categories of the first object and the second object are the same, the server may obtain N vertex coordinates of the first object and the second object, where N is a positive integer, then combine the N vertex coordinates into an object coordinate set, establish an index relationship between the N vertex coordinates and the first object and the second object, and finally store the object coordinate set and the index relationship as the first target object data.
Illustratively, the first object and the second object may both be line objects. The vertex coordinates of the first object may be (0, 1) and (1, 2), and the vertex coordinates of the second object may be (1, 3) and (3, 4). The server may obtain 4 vertex coordinates: (0, 1), (1, 2), (1, 3), (3, 4). The 4 vertex coordinates may then be combined into one object coordinate set { (0, 1), (1, 2), (1, 3), (3, 4) }. Establishing index relation between 4 vertex coordinates and the first object and the second object: a.fwdarw.0, 1, A.fwdarw.1, 2, B.fwdarw.1, 3, B.fwdarw.3, 4, wherein A represents a first object and B represents a second object. Finally, the server may store the 4 vertex coordinates and index relationships as first target object data for the electronic device to render and display the first object and the second object in the target engineering drawing.
S403, the server stores the first target object data into the first vertex buffer object VBO.
Specifically, the vertex cache object (Vertex Buffer Object, VBO) permits vertex array data to be stored in the high performance graphics card memory at the server side and provides for efficient data transfer. VBO creates "cache objects" for vertex attributes in server-side high-performance memory and provides access functions referencing these arrays, which are identical to functions used in vertex arrays, such as glvertex pointer (), glNormalPointer (), glTexCoordPointer (), and the like.
Memory management in VBO places the cache object in the most appropriate memory location according to user cues ("target" and "use" modes). Therefore, the memory management can optimize the cache by balancing the three memories of the system, the AGP and the graphics card memory.
Unlike the display list, the data in the VBO can be read and updated by mapping the buffer into the client memory space.
Another important advantage of VBO is that cached data can be shared across multiple clients as well as display lists and textures. Because VBO is at the server side, multiple clients can access the same cache through corresponding identifiers.
S404, the electronic equipment sends a display instruction to the server.
When the electronic equipment needs to display the target engineering drawing, the electronic equipment can send a display instruction to the server. The display instructions may carry the target engineering drawing identification to display the target engineering drawing.
S405-S406, after receiving a display instruction sent by the electronic equipment, the server sends first target object data stored in the first VBO to the electronic equipment.
S407-S408, after the electronic equipment receives the first target object data sent by the server, rendering and displaying a first object and a second object in the target engineering drawing.
After receiving the first target object data sent by the server, the electronic device may Call a Web graphics library interface, such as a Draw Call command, to render the first target object data, and display the first object and the second object in the target engineering drawing.
Through the method, the objects in the target engineering drawing can be classified in advance on the server, each class of objects are combined and then are respectively and correspondingly stored in one VBO, and then a Draw Call command is respectively called for each VBO on the electronic equipment to render and display, so that the Call times of the Draw Call are reduced, the rendering efficiency is improved, and the display performance is improved.
Stage two (S409-S416): pointing object and marking information display thereof
S409-S410, after the electronic equipment finishes rendering and displays the first object and the second object in the target engineering drawing, the electronic equipment receives the click operation of the user, and determines the first object corresponding to the click operation based on the click coordinate position and the index relation of the click operation.
Specifically, after receiving the click operation of the user, the electronic device may determine the first object corresponding to the click operation based on the coordinate position of the click operation and the index relationship in the first target object data.
S411-S413, the electronic device sends a first instruction to the server, the server receives the first instruction sent by the electronic device, determines that the first instruction corresponds to the first object, and stores coordinate point data of the first object into the second VBO.
S414-S416, the server sends coordinate point data of the first object to the electronic equipment, the electronic equipment receives the coordinate point data of the first object sent by the server, renders and displays the first object, and displays marking information at the position of the first object.
The marking information may include a color mark, a highlighting mark, and other marking information, which is not limited herein.
The pointing object is exemplified by the first object, and the pointing object may be the second object, which is not limited herein.
Through the method, the electronic equipment can select the object in the target engineering drawing, such as the first object, by utilizing the default click function in the Web graphic library, obtain the corresponding index relation, and then map the corresponding index relation to the object before merging according to the index relation, so that the effect of independently picking and highlighting the object before merging can be realized.
Stage three (S417-S423): object display after modifying coordinate points
S417-S419, after the electronic device finishes rendering and displays the first object and the second object in the target engineering drawing, the electronic device sends a second instruction and coordinate point modification data to the server, and the server responds to the second instruction to replace the coordinate point data of the first object with the coordinate point modification data.
S420, the server merges the coordinate point modification data of the first object and the coordinate point data of the second object into second target object data, and stores the second target object data into a third VBO.
S421-S423, the server sends second target object data to the electronic equipment, the electronic equipment receives the second target object data sent by the server, and the first object and the second object after the coordinate point is modified in the target engineering drawing are rendered and displayed.
The object after modifying the coordinate point is exemplified by the first object, and the object after modifying the coordinate point may be the second object, which is not limited herein.
Through the method, the electronic equipment can render and display the object after the coordinate points are modified, namely, the effect of independently modifying and displaying the object before combination can be realized.
In some embodiments of the present application, the above-described stages two (including steps S409-S416) and three (including steps S417-S423) are optional. For example, in some embodiments, the method may perform only the steps in the second stage (including steps S409-S416) after performing the steps in the first stage (including steps S401-S408). In other embodiments, the method may perform only the steps in the third stage (including steps S417-S423) after performing the steps in the first stage (including steps S401-S408).
