Embodiment Construction

[0030] figure 1 It shows that different views of left and right eyes are generated due to binocular parallax, and the views of left and right eyes are called left and right view frames (view frames) respectively. The objects in the left and right view frames are related to the depth of field, which is called depth (Depth).

[0031] figure 2 A system architecture diagram of the 3D browser of the present invention is shown, which is composed of three modules: a 3D web page parser 200 , a 3D rendering engine 210 and a 3D transmission format processor 220 . The 3D web page parser 200 includes an HTML parser 201 and a CSS parser 202 .

[0032] image 3 It is a flow chart of the present invention, wherein the left half of the figure is the process of creating a 3D web page, and the right half is the process of parsing, rendering and processing the 3D transmission format by the 3D browser.

Abstract

The invention relates to a method for realizing 3D (three dimensional) browser based on binocular parallax principle. By using the method, a 3D webpage and a 3D video shown on a 3D television both have stereoscopic perception and depth perception. The method is characterized in that a 2D (two dimensional) positioning attribute in a cascading style sheet (CSS) used for controlling appearance of browser is expanded into a 3D positioning attribute for controlling the appearance of the 3D webpage having depth perception, wherein the 3D positioning attribute comprises the 2D positioning attribute and a 3D special positioning attribute, and the 3D special positioning attribute can be defaulted. The method comprises the following steps: 1) drawing 3D left and right viewing frames; 2) acquiring the 3D positioning information; 3) establishing the 3D webpage; 4) analyzing the 3D webpage; 5) rendering the 3D left and right viewing frames; and 6) processing a 3D transmission format. The method has the advantages that the 3D webpage can be formed by modifying the existing 2D webpage, the 3D browser is compatible with the 2D browser, the seamless support for the 2D webpage and the 3D browser isachieved, and the like.

Description

technical field [0001] The present invention relates to the field of computer science and technology, in particular to a 3D browser (3D Browser), which is based on the principle of binocular parallax and can display 3D webpages ( Including 3D graphical user interface in the form of web pages), presenting a three-dimensional world with depth of field and layering just like 3D video. The 3D web page may be placed on a certain website of the World Wide Web (WWW), or may be a local resident file. Background technique [0002] When human eyes observe a three-dimensional object, since the eyes are horizontally separated in two different positions, the images of the object seen are different. The images seen by the left and right eyes are called left view and right view respectively, and there is a parallax between them. Due to the existence of parallax, through the human brain, you can feel a 3D world with depth and layering, which is the principle of binocular parallax. Accord...
