ABSTRACT
Rendering efficiently a massive amount of local light sources had already been solved by methods such as tiled deferred shading [Andersson 09], tiled forward shading [Billeter et al. 13], and clustered deferred and forward shading [Olsson et al. 12]. However, generating appropriate shadows for a large number of light sources in real time is still an ongoing topic. Since accurate shadows from direct lights significantly improve the final image and give the viewer additional information about the scene arrangement, their generation is an important part of real-time rendering.
