Embodiment

[0024] Such as figure 1 Shown, a browser-based 3D scene construction method, the method includes the following steps:

[0025] In step s101, an original 3D scene model is made, and the original 3D scene model is compressed into a required 3D scene file through a 3D compression algorithm, and saved to a server. The three-dimensional compression algorithm includes two steps of scene data compression and texture data compression.

[0026] Step 1: Compression of scene data

[0027] The scene data consists of a vertex (Vertex) to form a triangle (Triangle), a triangle to form a geometry (Mesh), and frame data to form a key frame animation (KeyFrame Animation) and a skeleton animation (SkeletonAnimation). The division algorithm finds a large number of identical or similar points, surfaces and geometric bodies, reanalyzes and organizes the spatial information, and finally compresses the scene data source from hundreds of megabytes to several megabytes.

[0028] Step 2: Compression...

Abstract

The invention relates to a three-dimensional scene construction method based on a browser. The method includes producing an original three-dimensional scene model, compressing the original three-dimensional scene model into a required three-dimensional scene file through a three-dimensional compression algorithm, and storing the file in a server; downloading the three-dimensional scene file on the server through the browser, setting a download thread count according to the size of the file, and setting the download priority of the three-dimensional scene file simultaneously; loading the downloaded three-dimensional scene file in a resource manager of a client; and rendering a three-dimensional scene in the resource manager to generate a final three-dimensional scene. Compared with the prior art, the construction method has the advantages of being rapid in scene download speed, high in rendering efficiency, capable of improving operating speed and the like.

Description

technical field [0001] The invention relates to a three-dimensional scene modeling method, in particular to a browser-based three-dimensional scene construction method. Background technique [0002] With the continuous advancement of Internet technology, the content on the Internet has become increasingly rich from simple text to pictures, from video to Flash. It's getting easier and faster. However, 3D technology has not been able to run directly on the network. The main reason is that the amount of 3D data is too large and requires a long waiting time for downloading. [0003] Although the hardware performance of computers is constantly improving, and the network speed is also increasing, 3D itself has a large amount of data and relatively high hardware requirements. The current mainstream hardware environment and network speed environment support it is still limited. . Therefore, in order to realize real three-dimensional interactive content that simulates the real wor...
