Embodiment

[0026] Such as figure 1 As shown, a three-dimensional web page multi-scene fast switching method, the method includes the following steps:

[0027] 1) According to the position of the camera, obtain all the target and area panoramas that need to be displayed;

[0028] 2) Determine whether the required scene data is in the local resources, if so, then directly perform step 3), if not, then download the required scene data from the resource server, and then perform step 3);

[0029] 3) Load the required scene data into memory;

[0030] 4) According to the data information of the current scene, all the model data of the scene are loaded into the scene, and the parameters of the rendering queue are added to render all the models in groups;

[0031] 5) According to the current camera angle of view, transfer all model data in the angle of view to the video memory for rendering without releasing memory resources;

[0032] 6) When switching to other scenes, reset the parameters of ...

Abstract

The invention relates to a three-dimensional webpage multi-scenario fast switching method, which comprises the following steps of 1, obtaining all target and region panorama to be displayed according to the position of a camera; 2, judging whether the required scenario is in local resources or not, if so, directly executing the third step, and if not, downloading the required scenario data from a resource server and executing the third step; 3, loading the required scenario data into a memory; 4, completely loading model data of different scenarios into the scenario according to the data information of the scenario, and adding parameters of render arrays; 5, transmitting all model data in the group into a video memory for rendering according to the current position of the camera; and 6, resetting the parameters of render arrays of corresponding models when the scenario is switched to other scenarios. Compared with the prior art, the three-dimensional webpage multi-scenario fast switching method has the advantages that the frame clamping and frame falling phenomena are few, the scenario switching smoothness is high, and the like.

Description

technical field [0001] The invention relates to a method for loading and displaying a webpage, in particular to a method for fast switching between three-dimensional webpages and multiple scenes. Background technique [0002] With the rapid development of Internet technology, the traditional web technology and forms of expression have also undergone drastic changes. In the past two years, more and more 3D web games and virtual display technologies have been applied to online platforms on the Internet. Inevitably, unlike the traditional client-side 3D technology, web 3D will face greater technical challenges. One of them is that webpage 3D will face more user groups, and the hardware configuration of users' computers and the support of browsers for 3D technology are various and uneven. Therefore, it is very important to optimize and rationally use the rendering efficiency of the 3D engine. [0003] The basic steps of engine rendering of traditional webpage 3D technology ma...
