Video-based 3D graph real-time rendering method and video-based 3D graph real-time rendering system

Abstract

The invention provides a video-based 3D (three-dimensional) graph real-time rendering method. According to the method, rendering is achieved through a 3D graph pre-rendering link and a playing link, in the 3D graph pre-rendering link, picture content is subjected to pre-rendering operation, and then the change process of a 3D picture is recorded into a video. Then in a playing link, interaction operation identification is carried out on a user, so that playing progress control of the video is realized, and an equivalent graphic rendering effect is realized. The method is high in portability and reusability.

Description

technical field [0001] The invention relates to the technical field of 3D graphics rendering, in particular to a video-based 3D graphics real-time rendering method and system thereof. Background technique [0002] 3D rendering is to present the model from the 3D model grid to a 2D image with high realism through computer calculation. The calculation process includes comprehensive variables such as light and auxiliary light, material material and texture, and camera related settings. 3D rendering can be rendered on the local computer, but the efficiency is low and the rendering time is long. For anxious projects and scene projects, you can try cloud rendering, which can be rendered in batches, and the results can be produced in batches, saving rendering time, improving work efficiency, and getting twice the result with half the effort. [0003] The existing 3D graphics rendering technology has the following disadvantages: 1. The existing solutions in the industry generally u...

Problems solved by technology

3D rendering can be rendered on the local computer, but the efficiency is low and the rendering time is long

[0003] The existing 3D graphics rendering technology has the following disadvantages: 1. The existing solutions in the industry generally use the same engine for rendering and playback

For the player, the picture effect is limited by the rendering capability of the engine

If the rendering capability of the engine is not good enough, it will not be able to provide ideal picture effects;

[0004] 2. It is difficult to transplant, and the used resources / source codes are difficult to transplant from a project using one engine to a project using a different engine;

[0006] 4. The size of the package is too large, the more detailed and gorgeous the picture effect, generally speaking, the more resources are needed, and the final package size of the client is also larger;

[0007] 5. The reusability is low. For the images that have been rendered, they still need to be rendered again in the subsequent real-time rendering process.

It is difficult to reuse the results that the hardware has already calculated
