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 occupy the vast majority of the current 3D display programs, and the ESRI 3D GIS module does not break through the above limitations. During the modeling process, the user can only see the perspective 3D of a single channel, and cannot achieve true 3D stereoscopic display. Cannot achieve optimal application effect

Embodiment 1

[0058] Such as figure 2 and image 3 As shown, since the ESRI 3D GIS modules all use OpenGL API as the 3D rendering API in the modeling stage, this embodiment is based on the OpenGL API as the implementation object, and the operating system platform is Windows XP for implementation.

[0059] The interception and monitoring of OpenGL API 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 As shown, the implantable true three-dimensional rendering method for ESRI three-dimensional GIS module software, the method comprises the following steps:

[0061] Step (1) monitors and intercepts rendering data for the OpenGL API used by the ESRI 3D GIS module;

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

[0063] St...

Embodiment 2

[0084] An implantable true three-dimensional rendering method for ESRI three-dimensional GIS module software, including the interception of the following functions:

[0085] a. Create the function of the 3D display environment, monitor the function, add the system detection function calling the 3D 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....

Abstract

The invention discloses an implanted type true three-dimensional rendering method oriented to an ESRI three-dimensional GIS module, which comprises the following steps: capturing the original single-channel color signals and depth signals, and three-dimensional scene transformation matrixes and projection transformation matrixes by an implanted type rendering data interception technique between a 3D API call and graphics card display adopted by an ESRI three-dimensional GIS module software; parsing the information to reconstruct rasterize three-dimensional data; based on the principle of stereo vision, adaptively re-transforming the scene into two different view point locations to form binocular vision three-dimensional stereograph capable of being displayed three-dimensionally and drive the graphics card to perform three-dimensional output on the binocular three-dimensional stereograph; and performing true three-dimensional display and observation by making use of polarized, red and green, and blinking glasses, and the like. The implanted type true three-dimensional rendering method can achieve true three-dimensional scene display under the condition that the procedures and the operating modes of the prior ESRI three-dimensional GIS module software are not changed.

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 ESRI three-dimensional GIS module 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 form of GIS, 3D GIS is an important 3D application system. ESRI is the world's largest supplier of GIS software. Its 3D GIS modules include ArcScene, 3D Analysis extension module under ArcView and 3D virtual globe. Software ArcExplorer. [0003] It is a trend to realize stereoscopic vision in 3D applications. To observe a stereoscopic scene on a single display device, it i...
