| titleOfInvention | Global illumination rendering method based on virtual point light source and sparse matrix regression |
| abstract | The invention discloses a global illumination rendering method based on a virtual point light source and sparse matrix regression. According to the global illumination rendering method, a large quantity of virtual point light source models are adopted to build a light tree of a geometry scene to be rendered, visual sampling points are classified through a clustering method, the various visual sampling points are processed in a classification mode, and for processing of each class of visual sampling points, a light transmission matrix of the corresponding class of visual sampling points is built. The global illumination rendering method combines the advantages of a large quantity of point light sources and sparse matrix regression, the light transmission matrix is divided into sub-matrixes in the rendering process, the problem of a large number of point light sources is divided into sub-blocks to be processed, sparse matrix regression is carried out on the sub-matrixes, and therefore the effect and speed of global illumination rendering are improved. |
