The invention provides a method, a system, equipment and a medium for realizing online viewing of an original style of an Excel file, and belongs to the technical field of online file processing, the method comprises the following steps: a front-end Web page receives the Excel file uploaded by a user, stores the Excel file in a rear-end server and records stored file information; the Excel file is read, an xlsx.js library and an excel.js library are used for analysis, and analysis results are integrated; missing cell filling and style information conversion are carried out on the analyzed Excel file, cells with merging attributes in the Excel file are marked, and a format capable of being recognized by a data grid editor is obtained; and rendering a table consistent with the style of the original Excel file on a front-end Web page based on a format which can be identified by the data grid editor. The problem that a traditional online Excel viewing tool cannot completely reserve original file style information is solved, and the user experience is improved.

The invention provides an intelligent graph loading and rendering method and system for a mobile device application program, and the method comprises the steps: S1, initializing an SDK parameter of an intelligent graph development unit, and returning the SDK parameter to a mobile device; s2, the intelligent graph development unit collects sensor data and system performance data of the mobile device and user interaction behavior data of an application program, and uploads the data to a server; a prediction model is embedded in the server; s3, the server trains the prediction model through the sensor data and the system performance data of the mobile device and the user interaction behavior data of the application program, and predicts the user behavior trend and the device performance; s4, the intelligent graph development unit analyzes the predicted user behavior trend and equipment performance, and generates an intelligent graph loading and rendering strategy; the mobile device calls and executes the intelligent graph loading and rendering strategy, and intelligent graph loading and rendering are conducted on the application program of the mobile device. The running efficiency of the application program and the performance of the mobile equipment are improved.

The application provides a three-dimensional rendering engine for multi-source design model integration of ocean petroleum engineering, relates to the field of computer graphics and three-dimensional visualization technology, and comprises four layers of technical architecture: a cloud rendering layer realizes high-performance graphics processing based on a Vulkan API; a cloud transmission layer is responsible for pixel stream transmission and instruction interaction; an integrated SDK layer encapsulates common interfaces; and an application docking layer realizes business development. A service-side rendering plus pixel stream pushing technical route is adopted, low-delay video transmission is realized through WebRTC, instruction interaction is realized in combination with an MQTT protocol, rendering calculation is concentrated on the service side, and the client only needs to process video stream decoding. The model browsing frame rate of the application is not lower than 20 frames per second, the first preloading time is less than 1 minute, and the system response time after preloading is less than 3 seconds, so that the smooth display problem of large-scale three-dimensional models on ordinary terminal devices is effectively solved, and high-fidelity three-dimensional visualization support is provided for the whole business process of ocean engineering.

The invention relates to a view display method based on a virtual list, which comprises the following steps of: when a sliding event is triggered, starting an anti-jitter timer, and initiating a rendering request for DOM (Document Object Model) elements after timing is finished; the skeleton screen information is presented as a temporary interface in the rendering loading process; sequentially loading all DOM elements involved in the rendering request into a virtual storage list according to the positions of the DOM elements in the interactive interface; writing the data in the current screen and the data of the upper screen and the lower screen into a virtual list; and rendering the DOM elements in the virtual list. According to the method, by means of reducing DOM operation, controlling the number of elements, using an anti-shake technology and data caching and the like, the sliding performance and the user experience of the applet are effectively improved, the lagging and waiting time is shortened, meanwhile, system resource utilization is optimized, network pressure is reduced, the maintainability and the expansibility of codes are enhanced, and the user experience is improved. And finally, user retention and activeness are promoted, and powerful support is provided for business development.

According to the point cloud data display method and device, the storage medium and the computer equipment provided by the invention, when the point cloud data is displayed, the request LOD value and the loaded LOD value corresponding to the point cloud voxel in the current viewport can be determined firstly, and then the point cloud block loading task is generated according to the request LOD value and the loaded LOD value corresponding to the point cloud voxel, so that the point cloud block loading efficiency is improved. According to the method, a point cloud block loading task is added to a request pool, and the point cloud block loading task in the request pool is executed through multiple threads, so that the operation of a user on a main program is prevented from being blocked, and finally, when a triggering opportunity is reached, the loaded point cloud blocks can be merged to corresponding point cloud voxels in a memory to be displayed and updated, and the user experience is improved. Therefore, the user can quickly and smoothly browse the required content when observing the point cloud data. The process not only improves the stability and response speed of the large-volume point cloud browsing operation, but also avoids invalid data loading and redundant memory occupation, thereby improving the user experience.
