“…Flow simulation and visualization are used to show the distribution of flow field characteristics and dynamic processes, as well as to provide practical warnings for river shipping navigation [15]. Ships can locate their positions via GPS in the 3D virtual geographical environment and obtain the flow conditions around them.…”

“…River ship navigation is associated with a variety of information about flow conditions, such as flow velocity, water depth, river boundaries, and vortices. Flow visualization is important to illustrate the dynamic flow distribution and elucidate the laws of water motion, which are very important for safe river shipping [15,16]. A variety of available visualization methods can express flow information comprehensively and help to build a hybrid flow environment.…”

The flow in meandering rivers is characterized by rapid changes in flow velocity and water level, especially in flooded environments. Accurate cross-sectional observation data enable continuous monitoring of flow conditions, which is important for river navigation. In this paper, cross-sectional data based flow modeling and rendering methods are studied to build an interactive hybrid flow environment for three-dimensional river shipping. First, the sparse cross-sectional data are extrapolated and interpolated to provide dense sampling points. Then, the data are visualized separately by dynamic texture mapping, particle tracking, streamline rendering, and contour surface rendering. Finally, the rendering models are integrated with ship animation to build a comprehensive hybrid river navigation scenario. The proposed methods are tested by visualizing measured cross-sectional data in the Yangtze River using an open-source software, called World Wind. The experimental results demonstrate that the hybrid flow rendering achieves comprehensive visual effect and the rendering frame rate is greater than 30. The interactive hybrid flow visualization is beneficial to support river shipping analysis.
