Web AR object continuous loading method, apparatus and device

Abstract

The invention provides a Web AR object continuous loading method, apparatus and device. The method comprises the steps of sending a request of downloading an AR model to a remote server when a Web browser loads a page; receiving AR model data returned according to the request of downloading the AR model by the remote server; according to static model data in the AR model data, generating a staticmodel, and binding model animation data in the AR model data to the static model; and based on the static model bound with the model animation data, rendering a 3D animation model in the Web browser according to a specific triggering event or at a time node preconfigured by an animation configuration file. The problem of poor timeliness caused by serious delay generated by rendering a series of actions after downloading, building and loading the 3D model during 3D model rendering is avoided; and the workload of the Web browser is balanced.

Description

technical field [0001] The present invention relates to the technical field of virtual reality, and more specifically, to a method, device and equipment for continuously loading Web AR objects. Background technique [0002] With the rise and promotion of virtual reality technology VR (Virtual Reality) and augmented reality AR technology (Augmented Realty), high requirements are placed on the interaction between 3D models and the virtual or real world. Especially with the improvement of the performance of web browsers and the improvement of WebGL specifications, it is possible to realize VR and AR interaction on web browsers, so the real-time loading and rendering of 3D models, especially models with animation effects, on web browsers appears to be particularly important. [0003] WebGL (Web Graphics Library) is a 3D drawing protocol. The drawing technology standard of WebGL allows JavaScript and OpenGL ES 2.0 to be combined. By adding a JavaScript binding of OpenGL ES 2.0, ...

Problems solved by technology

[0005] The advantage of this method is that you can choose to render a specified model in the browser at a specific moment according to your needs, and you can use it anytime you want; but there are also obvious disadvantages: 1. When the details of the external model are exquisitely made, the external model is too large, It can even be as high as hundreds of megabytes. If the model needs to be loaded when a specific interaction event is generated, the model will be downloaded and rendered in the web browser at one time, and the rendering speed will be very slow, and the real-time
