Left/right-eye three-dimensional picture drawing method for three-dimensional (3D) virtual scene containing fuzzy reflection effect

Abstract

The invention discloses a left / right-eye three-dimensional picture drawing method for a three-dimensional (3D) virtual scene containing a fuzzy reflection effect, and belongs to the technical field of drawing of 3D virtual scenes with sense of reality. The traditional left / right-eye three-dimensional picture drawing method for the 3D virtual scene adopts a mode of respectively and independently drawing image pictures of a left-eye virtual camera and a right-eye virtual camera to draw a three-dimensional picture. According to the method, drawing programs for the image pictures of the left-eye virtual camera and the right-eye virtual camera are respectively and simultaneously executed on a dual-core central processing unit (CPU), the image picture of the left-eye virtual camera is drawn from a first-row pixel, and the image picture of the right-eye virtual camera is drawn from a last-low pixel, so the reusability of calculation results of incidence radiant brightness during drawing of the image pictures of the left-eye virtual camera and the right-eye virtual camera are ensured. By an interpolation method based on gradient, the calculation results of the incidence radiant brightnessare reused during drawing. Compared with the traditional method, the invention has the advantages that: the speed of drawing the 3D virtual scene is increased by 20 to 35 percent.

Description

technical field [0001] The invention belongs to the technical field of realistic 3D virtual scene rendering, and relates to a method for rendering a left and right eye stereoscopic image of a 3D virtual scene with blurred reflection effects. Background technique [0002] As an emerging computer art in recent years, 3D animation film has a very rapid development momentum and has been widely used in many industries. In order to produce a stronger visual impact, many 3D animated films currently have stereoscopic visual effects. The basic principle of the stereoscopic visual effect is that when the audience is watching an animated movie, the left and right eyes can see the images taken by the virtual camera of the left and right eyes without interfering with each other, and then through the synthesis of the human brain, the screen will finally be generated. Effect. [0003] In order to improve the realism of the 3D animation movie screen, it is often required to add the global...

Problems solved by technology

Therefore, the same point on the surface of the object in the 3D virtual scene usually has not exactly the same illumination value in the pixels of the image frame of the left-eye virtual camera, which makes the blurred reflection lighting calculation of the image frame of the left-eye virtual camera The result is difficult to multiplex directly in the image frame of the right-eye virtual camera
