Abstract:

This paper presents a novel approach to integrating the 3D flow visualization based on geometric primitives into a virtual reality system. Its main goal is to capture the essential flow patterns and to provide a strong sense of immersion. First, critical points of the flow field are extracted and clas sified to identify the regions with important flow patterns. Different seeding templates are then used around the vicinity of these critical points. Nex t, we present a new method to create streamtubes from primitive streamlines. Finally, the visualization result is integrated within an interactive post- processing unit. Altogether, wearing stereo glasses and head-mounted tracer, the user can capture the important flow features clearly.
