ABSTRACT
In this paper, we propose an interactive rendering method for taking into account global illumination using light path precomputation and a hierarchical data structure for fast final gathering. Our method can render static scenes interactively allowing the user to move the viewpoint and the positions of local light sources. More-over, our method can change the materials (including the textures, diffuse and low-frequency glossy BRDFs) of objects at run-time. In recent years, many methods have been proposed to achieve interactive rendering by precomputing light transfer, for example, [Hasan et al. 2006]. These methods, however, do not allow the user to modify the materials of objects interactively.

Real-time global illumination using precomputed light field probes
I3D '17: Proceedings of the 21st ACM SIGGRAPH Symposium on Interactive 3D Graphics and GamesWe introduce a new data structure and algorithms that employ it to compute real-time global illumination from static environments. Light field probes encode a scene's full light field and internal visibility. They extend current radiance and irradiance ...
Precomputed illuminance composition for real-time global illumination
I3D '16: Proceedings of the 20th ACM SIGGRAPH Symposium on Interactive 3D Graphics and GamesIn this paper we present a new real-time approach for indirect global illumination under dynamic lighting conditions. We use surfels to gather a sampling of the local illumination and propagate the light through the scene using a hierarchy and a set of ...
