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 Skyline 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] like figure 2 and image 3 As shown, since Skyline uses Direct3D API as the three-dimensional rendering API in the modeling stage, this embodiment is based on 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] like figure 1 Shown, the real three-dimensional display method for Skyline, the method includes the following steps:

[0061] Step (1) monitor and intercept rendering data for the Direct3D API used by Skyline;

[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 two diffe...

Embodiment 2

[0084] A true 3D stereoscopic display method for Skyline, 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 frame buf...

Abstract

The invention discloses a real three-dimension display method facing to Skyline which includes steps as follows: using an embedded romance data holding up technique between 3D API transferring and display card displaying used by the software; capturing original single chunnel color signal and deep signal, three-dimension scene transformation matrix and projecting transformation matrix; analyzing the information and reconstructing rasterized three-dimension data; self adaptive transforming the scene to two various visual point positions renewedly for forming a dual-eye visual three-dimension image pair for three-dimension displaying, and a driving display card processing three-dimension outputting to the dual-eye three-dimension image pair; processing real three-dimension scene display and observation by using polarization, red-green and fast close type glasses. The method can realize real three-dimension scene display in condition of no changing the program and the operation mode of the present Skyline software.

Description

technical field [0001] The invention relates to the technical field of three-dimensional visualization, in particular to a Skyline-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. Virtual Earth software, as an important three-dimensional application system, has attracted extensive attention for its rich data and friendly user experience, and Skyline 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 speci...
