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 VirtualEarth 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 Virtual Earth uses Direct 3D API as the three-dimensional rendering API in the modeling stage, this embodiment is based on Direct 3D 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, face the true three-dimensional stereo display method of VirtualEarth, this method comprises the following steps:

[0061] Step (1) monitors and intercepts rendering data for the Direct 3D API used by Virtual Earth;

[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...

Embodiment 2

[0084] A true three-dimensional display method for VirtualEarth, 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 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 th...

Abstract

The invention discloses an actual three-dimensional display method oriented to VirtualEarth, comprising: adopting implanted rendering data interception technology between calling of 3D API adopted by 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 current Virtual Earth 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 a true three-dimensional display method for Virtual Earth. 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 earth software has attracted extensive attention for its rich data and friendly user experience, and virtual earth 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...
