Problems solved by technology

However, due to the need for professional equipment, the high cost also limits the application of stereoscopic display technology, so the application of stereoscopic display cannot be promoted, and a large number of 3D programs are still displayed using single-channel technology, which lacks stereoscopic effect and loses the three-dimensional program. Stereoscopic display characteristics
At the same time, because stereoscopic display requires special hardware and special programming skills, a large number of programs have not considered the characteristics of stereoscopic display during development, and have not implemented the function of supporting stereoscopic display in the program. Stereoscopic display is not possible on the hardware
These programs account for the vast majority of current 3D display programs. Google Earth and Sketch Up have not broken through the above limitations. During the modeling process, users can only see a single-channel perspective 3D display and cannot achieve true 3D stereoscopic display. , can not achieve the best application effect

Abstract

The invention relates to a true 3D display method oriented to Google Earth and Sketch Up. The method comprises the following steps: an implanted rendering data interception technology is adopted between invoking of a 3D API of software and display by a 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-adaptingmanner, 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 software such as Google Earth and SketchUp 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 rendering method for Google Earth and Sketch Up software. Background technique [0002] With the development of computer technology, stereoscopic display has become a commonly used technical means in the fields of environment simulation, simulation training, planning and design, etc., and even began to combine with movies and computer games to produce stereoscopic movies and true 3D games to integrate into people's daily life. As an important three-dimensional application system, the virtual earth software has attracted extensive attention for its rich data and friendly user experience. Google Earth software is one of them. Google Sketch Up is a 3D rapid modeling software launched in conjunction with Google Earth. , to provide ground object modeling tools for Google Earth. [0003] It is a trend to realize stereoscopi...
