Problems solved by technology

In addition, in the case of continuous improvement of computer digital image processing capabilities, if the screen is still divided into 6 sub-screens to process images, it is obvious that the resources of the computer are not fully utilized, and the operation and management are cumbersome.

Embodiment Construction

[0041] First, a brief description of some of the concepts involved in this article:

[0042] "Rendering camera" refers to a virtual camera in 3D animation production software;

[0043] "Rendering" refers to the process of using the rendering lens to perform virtual shooting in a computer's three-dimensional scene to generate a corresponding digital image. The effect is similar to the process of shooting with a real camera to generate a photo or film;

[0044] "Visual axis" is the direction of the rendering lens, which is equivalent to the optical axis direction of the real camera optical lens;

[0045] "Rendering surface" refers to the imaging surface when rendering with the rendering lens, which is similar to the film of a real camera. In 3D software, the rendering surface and the viewing axis are always perpendicular to each other, similar to the relationship between the film of a real camera and the optical axis of the lens;

[0046] The "effective view frustum" is the e...

Abstract

The invention relates to a method for making a three-dimensional movie image with a ring screen. In order to solve the problem that the best viewing point cannot deviate from the center of the ring screen when the existing three-dimensional animation software is making a three-dimensional movie with a ring screen, the present invention is in the three-dimensional software. The inscribed prism surface of N rectangular surfaces is used to approximately replace the cylindrical surface, and the base point 10 representing the best viewing point is deviated from the center 12 and axis 13 of the cylindrical surface; respectively, using N rectangular surfaces as reference surfaces, create and set N pairs Render the lens so that the two viewing axes of each pair of rendering lenses are perpendicular to the corresponding reference plane, and make each pair of left and right effective viewing cones take the corresponding reference plane as the common section; use these 2×N lenses to simultaneously render each of the three-dimensional scenes One frame; then, the images rendered by N left rendering lenses and the images rendered by N right rendering lenses are spliced ​​sequentially to form a cylindrical stereoscopic image with parallax effect and corresponding to the left and right eyes respectively, and finally a continuous Ring-screen three-dimensional movie screen with dynamic effects.

Description

technical field [0001] The invention relates to digital movie technology, in particular to a method for making ring-screen three-dimensional movie images by using computer three-dimensional animation software. Background technique [0002] Three-dimensional (3D) animation, as an emerging computer art in recent years, has been widely used in many industries. Three-dimensional animation is a virtual three-dimensional space given by the computer with special animation software. By building an object model, placing the model on the stage of this three-dimensional space, illuminating it with lights from different angles, and then endowing each part with dynamic and Intense texture gets the effect. When making 3D animation, you first need to create 3D models such as objects and backgrounds, and then let these models move in 3D space, and then use the virtual "camera" in the 3D animation software to "shoot" the movement process of the model, and finally create a lifelike animation...
