Real-time light shaft generation for indoor rendering

Realistic natural phenomena such as light shaft for indoor and outdoor environments are used in various applications. The main issue with the existing light shaft algorithms is not sufficient quality in real-time rendering. In this paper, we address this issue by proposing a hybrid technique based o...
