Abstract

The invention relates to an all-around spherical light field rendering method which comprises the following steps: a preparation step, namely preparing to input and load related files; pre-computing a latticed depth map of positions of reference cameras which are densely covered with a sphere; moving a rendering camera, enabling the moving range of the rendering camera to be the surface of the sphere, and calculating and identifying the reference cameras surrounding the rendering camera around the rendering camera; performing back projection on pixels of the rendering camera, and performing depth test with the four reference cameras; interpolating the reference cameras passing through the depth test, thereby obtaining the finally rendered pixel value. According to the method disclosed by the invention, the rendering results can be rapidly seen in real time; an object can be observed from any angle on the spherical surface, and a real immersion feeling can be felt.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a full-view spherical light field rendering method that can realize real-time rendering of real objects using multi-viewpoint images. Background technique [0002] Currently, known 3D model rendering engines use a combination of models and texture maps to render images using rasterization rendering pipelines. Most of the characters and scenes in the current game field are rendered using this method. However, with the development of virtual reality technology, such artificial rendering results are no longer in line with people's expectations because of the lack of realism. [0003] The current rendering engine mainly has the following two problems: [0004] First, it takes a lot of human resources to create rendering data. Specifically, it means that modelers need to spend a lot of time building a model similar to a real object, and debugging the material and texture o...
