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] The currently widely used 3D APIs include DirectX, OpenGL, Glide, Heidi, etc. Such as figure 2 and image 3 As shown, the present embodiment adopts OpenGL3D API as the implementation object, and the operating system platform is Windows XP. The embedded true three-dimensional driving method for computer graphics card is based on the principle of the manual, and the interception and monitoring of OpenGL API are developed based on Micorsoft Detours SDK. Detours is a development kit provided by Microsoft for API call interception under the Windows platform, supporting all Win32 applications.

[0061] Such as figure 1 Shown, an implantable true three-dimensional stereo driving method of a computer graphics card, the method comprises the following steps:

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

[0063] Step (2) using the scene transformation matrix and th...

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 driving method for computer graphics cards. Background technique [0002] With the development of computer technology, true three-dimensional stereoscopic display and observation has become a commonly used technical means in the fields of environment simulation, simulation training, planning and design, etc. people's daily life. [0003] Stereoscopic vision is due to the angular deviation of the same objects seen by the left and right eyes of a person, and parallax is formed in the brain, thereby forming a true three-dimensional sense. Therefore, in stereoscopic vision, the images seen by the left and right eyes need to be separated independently, and then the left and right eyes can see different images through specific external equipment to form stereoscopic vision through the physiological effects of the brain. Tr...
