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 most of the current 3D display programs, and GeoGlobe has not broken through the above limitations. During the modeling process, users can only see a single-channel perspective 3D, and cannot achieve true 3D stereoscopic display. good application effect

Embodiment 1

[0058] Such as figure 2 and image 3 As shown, since the GeoGlobe uses the Direct3D API as the 3D rendering API in the modeling stage, this embodiment is based on the Direct3D API as the implementation object, and the operating system platform is Windows XP for implementation.

[0059] The interception and monitoring of Direct3D 9 is developed based on Micorsoft Detours SDK. Detours is a set of development kits provided by Microsoft for API call interception under the Windows platform, which supports all Win32 platforms.

[0060] Such as figure 1 Shown, the true three-dimensional display method for GeoGlobe, this method comprises the following steps:

[0061] Step (1) monitor and render data interception for the Direct3D API used by GeoGlobe;

[0062] Step (2) using the scene transformation matrix and the projection transformation matrix to reconstruct the rasterized three-dimensional data;

[0063] Step (3) Adaptive screen resolution and human eye base distance to set t...

Embodiment 2

[0084] A method for true 3D stereoscopic display of GeoGlobes, including interception of the following functions:

[0085] a. Create the function of the 3D display environment, monitor the function, add the system detection function calling Direct3D API to the monitoring function, obtain the stereoscopic display characteristics of the system, and change the stereoscopic in the originally set display environment according to the corresponding stereoscopic display characteristics Display mode, enable true 3D stereoscopic display support on hardware that supports stereoscopic display, and set flags for red-green stereoscopic display on hardware that does not support stereoscopic display.

[0086] b. Start a frame drawing function, monitor the function, add code to the monitoring function to obtain the viewport size of the current drawing frame, and create a temporary buffer for the stereo pair according to the rendered pixel format.

[0087] d. The function of outputting the fram...

Abstract

The invention discloses a GeoGlobe-oriented true three-dimensional stereoscopic display method: adopting implanted render data intercepting technique between 3D API invocation and display card display used by the software, capturing original single channel color signal and depth signal, three-dimensional scene transformation matrix and projection transformation matrix; analyzing those information, refactoring rasterized three-dimensional data; adaptively transforming the scene into two different viewpoint positions to form binocular vision stereopair for providing stereoscopic display based on stereoscopic vision principle, driving the display card to carry out stereoscopic output on the binocular stereopair; carrying out true three-dimensional stereoscopic display and observation by polarization, red and green and flash-closed spectacles, etc. The invention can realize true three-dimensional stereoscopic scene display under the condition of not changing the program and operation mode of the existing GeoGlobe software.

Description

technical field [0001] The invention relates to the technical field of three-dimensional visualization, in particular to a GeoGlobe-oriented true three-dimensional display method. 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, virtual globe software has attracted extensive attention for its rich data and friendly user experience, and GeoGlobe software is one of them. [0003] It is a trend to realize stereoscopic vision in 3D applications. To observe a stereoscopic scene on a single display device, it is necessary to separate the images seen by the left and right eyes independently, and then use a spec...
