Problems solved by technology

However, due to the high cost of professional equipment and programming technology, the application of stereoscopic display technology is limited, so the application of stereoscopic display cannot be promoted. A large number of 3D modeling or visualization software systems use perspective transformation technology to process scenes to form monocular images. Visual single-channel rendering of images and display output, this kind of 3D display loses the stereoscopic display characteristics and immersion that 3D programs should have

Embodiment 1

[0060] Currently, the commonly used 3D APIs include DirectX, OpenGL, Glide, Heidi, etc. Such as figure 2 with image 3 As shown, this embodiment adopts OpenGL 3D API as the implementation object, and the operating system platform is Windows XP. The implantable true 3D stereo drive method for computer graphics cards is based on the principle of the manual, and the interception and monitoring of OpenGL API is developed based on Micorsoft Detours SDK. Detours is a set of development kits provided by Microsoft to intercept API calls under the Windows platform and supports all Win32 applications.

[0061] Such as figure 1 As shown, an implantable true 3D stereo driving method for a computer graphics card includes the following steps:

[0062] Step (1) Monitor the OpenGL API used by the 3D application software, intercept key functions of the OpenGL API, and obtain scene rendering data;

[0063] Step (2) Use the scene transformation matrix and the projection transformation matrix to reco...

Abstract

The invention relates to a true 3D display driving method aimed at a display card of a computer. The method comprises the following steps: an implanted rendering data interception technology is adopted between a 3D visualization program and the display card to capture an original single channel color signal, a depth signal, a 3D scene transformation matrix and a projection transformation matrix; rasterized 3D data is reconstructed by parsing the information; on the basis of the stereo vision principle, the scene is re-transformed to two different viewpoint positions in a self-adapting manner,so that a binocular vision stereopair to be displayed in a 3D form is formed, and the display card is driven to output the binocular vision stereopair in a 3D form; and polarization, a pair of red and green or blinking glasses, and the like are adopted for true 3D display and observation. The invention can realize true 3D scene display of the prior 3D visualization software without changing programs and operation modes.

Description

Technical field [0001] The invention relates to the technical field of three-dimensional visualization, in particular to an implantable true three-dimensional stereo driving method for a computer graphics card. Background technique [0002] With the development of computer technology, true three-dimensional display and observation have become common technical methods in the fields of environmental simulation, simulation training, planning and design, and gradually combined with movies, television, computer games, etc. to produce three-dimensional movies and televisions and true three-dimensional games. People's daily life. [0003] Stereo vision is due to the angular deviation of the same object seen by the left and right eyes of a person, and parallax is formed in the brain, thereby forming a true three-dimensional feeling. Therefore, in stereo vision, it is necessary to separate the images seen by the left and right eyes independently, and then use a specific external device to ...
