Adaptive three-dimensional rendering method based on mechanism of human-eye stereoscopic vision

Abstract

The invention relates to an adaptive three-dimensional rendering method based on a mechanism of human-eye stereoscopic vision, aiming at adaptively achieving three-dimensional rendering output on account of the three-dimensional visual program of single viewpoint perspective projection. The method comprises the following steps: setting adaptive three-dimensional rendering control parameters containing a rendering state control parameter for controlling adaptive three-dimensional rendering, a single viewpoint transformation parameter, a visual model parameter and a left and right-viewpoint adjusting parameter; selecting adaptive three-dimensional parameter generation algorithm: generating a pair of left and right-viewpoint transformation parameters required by three-dimensional rendering by synthesizing the single viewpoint transformation parameter and the visual model parameter; and setting an adaptive 3D rendering streamline model: dividing three-dimensional sense data after viewpoint transformation into two subrendering flows, and forming a left channel image by left viewpoint transformation and projection transformation, forming a right channel image by right viewpoint transformation and projection transformation, and forming a pair of three-dimensional output images by the left and right channels.

Description

technical field [0001] The invention relates to three-dimensional visualization technology in computer graphics, provides an adaptive binocular stereo vision rendering method, establishes an adaptive binocular stereo rendering pipeline model based on the method, and supports traditional non-stereoscopic three-dimensional display The three-dimensional display of the application program without any change can also simplify the existing three-dimensional rendering model, speed up the efficiency of the three-dimensional application program in the three-dimensional rendering, and reduce the difficulty of development. Background technique [0002] The human eye has a natural three-dimensional observation ability. With the help of the difference in the imaging of the same object in the left and right eyes, the brain can obtain the three-dimensional vision of the object. The classic computer real-time 3D rendering pipeline adopts a rendering model based on triangular patches. The in...

Problems solved by technology

However, this method requires the 3D application program to call the rendering process twice independently, and set the parameters of the left view point and the right view point respectively. The same data needs to be rendered twice independently to generate a stereo pair.

For programs that only use single-viewpoint rendering, they can only produce perspective projection effects, but cannot produce true 3D stereoscopic display effects, and most 3D applications are based on single-viewpoint perspective projection technology, so when these 3D applications are required When the program realizes true 3D stereoscopic output, the source code of the program must be changed to display and call the 3D stereoscopic rendering process
