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.
