Method for editing three-dimensional graph and image in real time by using timeline

Abstract

The invention discloses a method for editing a three-dimensional graph and an image in real time by using a timeline, which comprises the following steps of: 1, establishing an editing scene, and editing a three-dimensional graph material; step 2, adding videos and audios and three-dimensional graphic materials from different sources into the editing scene, and appointing a track and in-out time of the added videos and audios or three-dimensional graphic materials; constructing a logic layer, and placing the added video / audio or three-dimensional graphic material in the logic layer; 3, a timeline is constructed, the timeline is constructed by a plurality of tracks, and the aliasing sequence of the video and audio and the three-dimensional graphic materials is determined; 4, performing aliasing rendering on the video, audio and three-dimensional graphic materials according to the aliasing sequence to generate a final video; by means of the method, fine adjustment and modification of the attributes of the three-dimensional graph materials in the nonlinear video and audio editing context environment are achieved, the effect is presented in real time, and the quality and working efficiency of products output by nonlinear video and audio editing software are greatly improved.

Description

technical field [0001] The invention relates to the field of computer graphics, text and image processing, in particular to a method for real-time editing of three-dimensional graphics and images using a timeline. The method can perform real-time editing of three-dimensional graphics and images based on the timeline in nonlinear video and audio editing software. render. Background technique [0002] Currently, when 3D graphics materials need to be used in nonlinear video and audio editing software, the usual technical means are to convert the 3D graphics materials into videos, pictures or picture sequences externally, and then convert these videos, pictures or picture sequences. Import non-linear video and audio editing software for video and audio synthesis output. [0003] However, the technical means and methods usually used above have the following disadvantages: [0004] First of all, the technology of processing 3D graphics materials in the current nonlinear video an...
