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 Microstation 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 on the Windows platform, starting from the V8XM version, Microstation has begun to support the Direct3D API as a three-dimensional rendering API, so the following embodiments are based on the Microstation V8 XM version under Windows XP.

[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 As shown, the implantable true three-dimensional display method for Microstation, the method comprises the following steps:

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

[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 an...

Embodiment 2

[0084] A Microstation-oriented implantable true three-dimensional stereoscopic display method, 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....

Abstract

The invention relates an embedded truly three-dimensional stereoscopic rendering method facing Microstation, 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 currentMicrostationwithout changing programs and operation modes.

Description

technical field [0001] The invention relates to the technical field of three-dimensional visualization, in particular to a Microstation-oriented implantable 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. As an important 3D application system, 3D modeling software has become the key software in many industries. The computer-aided design software Microstation launched by Bentley is widely used in construction, machinery manufacturing, spatial data processing and other fields. [0003] It is a trend to realize stereoscopic vision in 3D applications. To observe a stereoscopic scene on a single display device, it is neces...
