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 ENVI / IDL does not break through the above limitations. During the modeling process, users can only see a single-channel perspective 3D, and cannot achieve true 3D stereoscopic display. achieve the best application effect

Embodiment 1

[0058] Such as figure 2 with image 3 As shown, since both ENVI / IDL use 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 rendering method for ENVI / IDL, the method includes the following steps:

[0061] Step (1) monitoring and rendering data interception for the OpenGL API used by ENVI / IDL;

[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 d...

Embodiment 2

[0084] An implantable true 3D stereoscopic rendering method for ENVI / IDL, 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 the 3DOpenGL 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 outp...

Abstract

The invention relates an embedded truly three-dimensional stereoscopic rendering method facing ENVI/IDL, comprising steps of using an embedded rendering data intercepting technology between ENVI/IDL adopted 3D API invocation and graphic card display to capture initial color signals and depth signals of single channel, 3D scene transformation matrix, and projection transformation matrix; analyzing the information, and reconstructing the rasterized 3Ddata; adaptively transform the scene into to two different visual points based on the principle of stereoscopic vision to form double-eye visual image pairs for stereoscopic display and drive the graphic card to stereoscopically output the double-eye visual image pairs; making use of polarization, red-green and blinking type glasses for truly three-dimensional stereoscopic display and observation. The invention is capable of displaying truly three-dimensional stereoscopic scene for current ENVI/IDL 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 ENVI / IDL 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. ENVI is a remote sensing processing software launched by ITT Company. As an important spatial data, satellite images can be superimposed with DEM to produce realistic 3D effects. IDL is a scripting language for 3D visualization and scientific computing launched by ITT Company. ENVI is developed based on this language. [0003] It is a trend to realize stereoscopic vision in 3D applications. To observe a stereosco...
