In this article, the anaglyph video maker is employed for generating realistic 3-D flows and the software FlowAnimator is developed using that technology. Based on Microsoft Windows Presentation Foundation ( WPF), the real 3-D scene is set up and marker particles are distributed in it randomly in order to create a more natural flow scenario. The trajectory of the particle motion is calculated with Lagrangian description in 3-D space. During the simulation, the viewport can be changed in order to focus on different parts of the model by panning, zooming, rotating and inclination variation etc. Marker particles may appear in different shapes: spheres, tracking-balls, cylinders and ribbons in order to fit different flows. It is the first time that the video anaglyph technology is employed in the 3-D hydrodynamic simulation, which removes the obstacles for 3-D scenes to be rendered on a flat-panel display.
