IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

A study to surface visualization of 3-d flow
Author : KANG SUHAI(1), LIU HONG(2)
ABSTRACT
Along with the improvement of computing technology and engineering requirements, 3-D hydrodynamic numerical
simulation is adopted partly in research area of water transportation and makes great progress. At the same time, it
proposed requirements to 3-D flow simulation. Carrying out visualization method to computation data becomes more
urgent, and research on 3-D flow visualization is an essential one. Visualization of 3-D surface is an important way to
discover the 3-D flow, which conforms to people¡¯s cognition habits to 3-D flow characteristics in the nature world. Based
on the lightweight 3-D graphic engine, a program called SS3D is developed with visual C#. SS3D sets up 3-D virtual
scene with the numerical model. It can be used to do interpolation of spatial-temporal discretization to computation
results with efficient algorithms. Meanwhile it carries out 3-D particle tracing for surface flow with Lagrangian law and
assists with semitransparent 3-D geometric surface to express the water surface. Also it makes the tracing particles be
displayed on the water surface, thus, makes the 3-D display effect achieved optimization. By demonstration of living
examples, it shows that visualization effect of the surface flow is satisfactory; the study achieves the expected effect and
has promoting effect on 3-D hydrodynamic simulation
