Abstract

The invention relates to a method for rendering a spherical light field in all viewing directions, which includes: a preliminary step, that is, to perform preliminary input and loading of related files; pre-calculate the depth map of the reference camera position densely distributed on the sphere in grid form; move the rendering camera, Its movement range is the surface of the sphere, and calculating and identifying the reference cameras surrounding it around the rendering camera; back-projecting the pixels of the rendering camera, and performing a depth test with the four reference cameras; interpolating the reference cameras that pass the depth test, The result is the final rendered pixel value. The invention can quickly and real-time see the rendering result; objects can be observed from any angle on the spherical surface, and a more realistic sense of immersion 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...
