However, the browser on the portable device can only process and present a limited amount of data to the user at a time, which is generally much smaller than the amount available from the personal computer web page, so there is a need to improve the method of accessing and loading the BIM web page

[0021] The method for displaying a BIM model on a webpage of the present invention includes a method and a system for filtering a BIM model display area of ​​a webpage to present to users. According to a first embodiment, the web browser retrieves the web pages containing the BIM model to be viewed and filters them to provide a customized viewing experience to the user. That is, a web page containing markup language describing various elements such as text, images, and graphics is received, analyzed to identify segments, and redrawed to enhance at least one segment. The layout of the object.

[0022] refer to figure 1 , first, the web page is downloaded and preferably cached in the device. More generally, browser 102 retrieves computer files that may contain both text and graphics or images. Preferably, said file is an HTML or other markup language file, eg accessible via a network as a web page. For illustration purposes, the markup language code will be described as HTML...

Abstract

The invention relates to a method for controlling BIM models to be displayed in webpages. In prior art, a synchronous transmission technology is used for displaying BIM models in webpages. According to the method, an asynchronous transmission technology is adopted, so that the technical problem that the user response speed is low as bandwidth and local temporary storage spaces of users are greatly occupied when BIM is displayed in webpages, and browsers are limited by the bandwidth and local memory storage speeds is solved. The method for controlling BIM models to be displayed in webpages comprises the following steps of: downloading a webpage and preferentially caching the webpage in equipment at a high speed; preferentially taking a browser as a complete webpage to storage the webpage for further processing; translating or rendering an html code corresponding to the complete page by the browser so as to generate an image of the webpage; analyzing the webpage and identifying related areas of the webpage; preferentially identifying boundaries of the areas to generate a proper control signal which is used for indicating the browser to refresh one or more of the identified areas, so that the loading time is shortened and the access efficiency is improved when a BIM model is displayed in the webpage.

Description

Technical field: [0001] The invention relates to a method for displaying a BIM model on a web page. Background technique: [0002] The existing web page shows that the BIM model uses synchronous transmission technology, and the bit grouping of synchronous transmission is relatively large. It does not send each character independently, each character has its own start bit and stop bit, but combines them together send. We refer to these combinations as data frames, or simply frames. [0003] The first part of the data frame contains a set of synchronization characters, which is a unique combination of bits, similar to the aforementioned start bit, used to inform the receiver that a frame has arrived, but it can also ensure the sampling speed of the receiver It is consistent with the arrival speed of bits, so that the sending and receiving parties enter into synchronization. [0004] The last part of the frame is an end-of-frame marker. Like the sync character, it is also a...
