This paper proposes a new group-based accelerating structure called hybrid structure for the ray tracing of dynamic scenes, whose main advantage is that we can choose a suitable local accelerating structure for each object in the scene. In the hybrid structure, the objects in the scene are organized into a hierarchical bounding volume structure by surface area heuristic (SAH) cost model with each...
At present, multiple scattering problems in participating media is still very challenging for real time rendering. Some methods have proposed to describe multiple scattering phenomena, however, there are some restriction conditions such as requiring the medium is static, etc., and rendering speed is not satisfied real-time requirement. In order to speed up the multiple scattering rendering, we propose...
