There is no appropriate 3D visualization system,which is targeted for deepwater channel regulation engineering of the Yangtze River.Available digital tools currently have not excellent visualization effect,and the dynamic data information inquiry is inconvenience,and those tools can not effectively reflect the situation in the process of riprap in time.This study develops a set of waterway engineering riprap section forming process visualization software based on the MATLAB platform,which has a fully independent intellectual property,targeted and 3D displaying.It can realize the visualization of 3D terrain display of original terrain,design terrain and riprap terrain.Through contrast before and after the riprap terrain,the software reflects leakage or super throw of riprap construction area in time,and it can help improve the schedule and accuracy of waterway regulation riprap construction engineering.
