A Survey of Ray Tracing Rendering of Large-Scale Scenes
Ray tracing is the most commonly used realistic rendering algorithm,which plays a great role in 3D animation,virtual reality,digital twin and other fields.The increasing demand for rendering quality has brought a lot of attention to large-scale scene ray tracing.In this paper,we review and analyze the related work on large-scale scene ray tracing.Firstly,we introduces the data organization of large-scale scenes from data compression and decomposition;secondly,we reviews the out-of-core ray tracing methods,and analy-ses the application of LOD in these methods;thirdly,we introduces the distributed ray tracing methods,and classifies them into to image-space parallel,data parallel,and hybrid parallel for analysis and comparison;finally,we summaries the research progress of large-scale scene ray tracing,analyze the problems of existing methods in data storage,data access,rendering quality,rendering speed,etc.,and point out the possible fu-ture research directions,including neural network-based scene data compression,instantiated scene data decomposition,computational hotspot prediction,and adaptive distributed strategies.
