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, and C Tech 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. The best application effect

Embodiment 1

[0058] Such as figure 2 and image 3 As shown, since C Tech uses the 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 display method for C Tech software, the method may include the following steps:

[0061] Step (1) Monitor and intercept rendering data for the OpenGL API used by C Tech;

[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...

Embodiment 2

[0084] An implantable true three-dimensional display method for C Tech 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.

[0087] d. The function of...

Abstract

The invention discloses an implanted actual three-dimensional display method oriented to C Tech software, comprising: adopting implanted rendering data interception technology between calling of 3D API adopted by the C Tech software and display of a display card to capture an original single-channel color signal, a depth signal, a three-dimensional scene transformation matrix and a projection transformation matrix; analyzing the information to reconstruct grid three-dimensional data; based on the stereoscopic vision principle, self-adaptively retransforming the scene to two different view point positions so as to form a binocular vision stereopair for stereoscopic display, and driving the display card to carry out stereoscopic output on the binocular vision stereopair; and utilizing polarization, red-green and blinking type glasses and the like to carry out actual three-dimensional display and observation. The method can realize the actual three-dimensional scene display for the prior C Tech software under the condition of not 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 display method for C Tech 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. Geological 3D software, as a professional 3D application software, has important applications in urban engineering and groundwater exploitation. C Tech software is a 3D geological visualization software running in the PC environment, including EVS, EVS-PRO, MVS and other modules, which can support the analysis and visualization of rich geological professional data. [0003] It is a trend to realize stereoscopic visio...
