Visualization Methods Study on Bridge Influence Estimation towards Riverway Flow Field

摘要

In order to realize the visualization of the riverway flood flow field, this paper focus on the Triangle Net Model in the Digital Elevation Model (DEM), using OpenGL method of illumination, material, texture map and antialiasing to realize the multi-dimensional visualization of river way terrain. The modeling transformation of removing, rotate and scaling in VC++ and OpenGL are also used in order to realize the dynamic displaying effect. Searching functions related to visualization and riverbank flood forecast can be realized after adding flooding data under various conditions. These functions are for the reference of flood control decision-making.
