Embodiment Construction

[0057] The present invention will be described in detail below in combination with specific embodiments.

[0058] Such as Figure 1-3 As shown, a method for converting a 3D model to a stereoscopic dual-viewpoint view, specifically includes the following steps:

[0059] Step 1: Select a pooled observation model

[0060] Observation models mainly include convergent observation models and parallel observation models. The present invention selects the convergent observation model.

[0061] attached figure 1 A schematic diagram of convergent projection, attached figure 2 A truncated pyramid for convergent projection. Among them, top, bottom, Left, and Right are the distances from the upper, lower, left, and right sides of the front clipping surface of the pyramid shared by the left and right eyes to the center, Near is the distance from the front clipping surface to the viewpoint, and Far is the distance from the rear clipping surface to the viewpoint.

[0062] Step 2: Calcu...

Abstract

The invention discloses a method for converting a 3D model into a three-dimensional double-viewpoint view. The method comprises the steps of 1), selecting a to-be-converted 3D model, calculating frustum shift and left and right eye frustum parameters of the 3D model according to input parameters, and establishing a projection matrix and a view matrix of a left eye and the projection matrix and the view matrix of a right eye; 2), obtaining left and right eye MVPs according to the projection matrixes, view matrixes and model matrixes of the left eye and the right eye and introducing the left and right eye MVPs into a shader; 3), carrying out premultiplication on a vertex coordinate of the 3D model and the left eye MVP, introducing a result into the shader, carrying out the premultiplication on the vertex coordinate of the 3D model and the right eye MVP, and introducing the result into the shader, thereby obtaining new vertex coordinates, after each vertex of the 3D model is converted, obtaining left and right eye images of the 3D model; and 4), mapping and splicing the obtained left and right eye images on a screen, thereby obtaining a double-viewpoint disparity map of the 3D model. The method is fast in operation speed, is approximate to visual habits of human eyes and satisfies double-eye convergence simulation.

Description

technical field [0001] The invention relates to 3D display technology, in particular to a conversion method for converting an OpenGL-based 3D model into a stereoscopic dual-viewpoint view, in particular to a method for converting a 3D model into a stereoscopic dual-viewpoint view. Background technique [0002] Humans live in a three-dimensional world and use stereo vision to perceive the world. With the rapid development of computer technology, computers describe the real world in more and more ways: from sound to images to video, the world that computers can represent is becoming more and more more complicated. At present, most display devices are still capable of 2D display, ignoring the depth information. In the era of digitalization and modernization, 2D display can no longer meet the needs of human beings, so 3D models have entered people's lives as a new media form. , study and work, and will soon be accepted by the general public. It has been more and more widely us...
