Embodiment 1

[0051] Such as figure 1 As shown, the method for realizing webpage loading of a three-dimensional model provided in the first embodiment includes the following steps:

[0052] Step 101: Decompose the three-dimensional model according to its assembly structure to form at least one first sub-model block, and obtain the storage space of the first sub-model block;

[0053] Wherein, the storage format of the first sub-model block is the first storage format.

[0054] Specifically, when the client needs to load a 3D model on a web page, in order to avoid web page crashes and crashes caused by loading the entire model, it is necessary to decompose the 3D model to form at least one first sub-model block , It is convenient for subsequent loading, thereby reducing the computing and rendering pressure of the graphics card and browser, and ensuring the loading speed of the model and the fluency of operation.

[0055] Step 102: sequentially compare the storage space of the first sub-model block wi...

Embodiment 2

[0070] Such as figure 2 As shown, the method for realizing webpage loading of a three-dimensional model provided by the second embodiment includes the following steps:

[0071] Step 201: Decompose the three-dimensional model according to its assembly structure to form at least one first sub-model block, and obtain the storage space of the first sub-model block;

[0072] Wherein, the storage format of the first sub-model block is the first storage format.

[0073] Specifically, when the client needs to load a three-dimensional model on a web page, in order to avoid web page crashes and crashes caused by loading the entire model, it is necessary to decompose the three-dimensional model to form at least one first sub The model block is easy to load successively in the later stage, thereby reducing the computing and rendering pressure of the graphics card and browser, and ensuring the loading speed of the model and the fluency of operation.

[0074] Optionally, this embodiment can use Bl...

Embodiment 3

[0100] Such as image 3 As shown, the device for realizing web page loading of a three-dimensional model provided by the third embodiment includes: a three-dimensional model decomposition unit 301, a first sub-model block comparison unit 302, a first sub-model block format conversion unit 303, and a first sub-model The block decomposition unit 304, the second sub-model block comparison unit 305, the second sub-model block decomposition unit 306, the second sub-model block format conversion unit 307, and the loading unit 308, wherein:

[0101] The three-dimensional model decomposition unit 301 is connected to the first sub-model block comparison unit 302, and is used for decomposing the three-dimensional model according to its assembly structure to form at least one first sub-model block, which is convenient for subsequent loading, Therefore, the calculation and rendering pressure of the graphics card and the browser is reduced, the loading speed of the model and the smooth operati...

Abstract

The invention discloses a webpage loading method and device for achieving a three-dimensional model. The method includes the steps that the three-dimensional model is decomposed according to the assembly structure to form at least one first submodel block, and storage space of the first submodel blocks is obtained; the storage space of the first submodel blocks is sequentially compared with a pre-defined threshold value of the storage space; when the storage space of the first submodel blocks is smaller than or equal to pre-defined threshold value of the storage space, format conversion is carried out on the first submodel blocks, and the storage space of the first submodel blocks is that of second storage format modules of the first storage format; the second storage format modules obtained after conversion are sequentially loaded into a three-dimensional scene of a page. The problems that in the prior art, a browser is caused to break down when the whole three-dimension model is loaded, and the three-dimensional model cannot be operated smoothly are avoided.

Description

Technical field [0001] The invention relates to the technical field of three-dimensional model loading, and more specifically, to a method and device for realizing webpage loading of a three-dimensional model. Background technique [0002] With the development of computer technology and GIS technology, 3D technology has been continuously promoted in many fields. Among them, the use of objective image 3D scenes to simulate the real environment and give people a vivid and intuitive display is a part that users are very concerned about. Based on the limitations of the browser itself, how to smoothly display and operate large-scale three-dimensional models on web pages has become a core issue of concern to those skilled in the field. [0003] The existing 3D model loading technology has many problems in actual operation. Due to the limitations of browsers and graphics cards, currently only small 3D models and scenes can be loaded and rendered normally on the web side; if you use the ex...
