Area of Science:

• Fluid Dynamics
• Scientific Visualization
• Computer Graphics

Background:

• Visualizing and analyzing 3D unsteady flow fields presents significant challenges.
• Existing methods often struggle with complex flow dynamics and reference frame limitations.

Purpose of the Study:

• Represented reference frame motions in a 6D parameter space, separating translational and rotational subspaces.
• Developed interactive tools for determining, filtering, and combining reference frames.
• Introduced observer-aware streamline/pathline filtering and iso-surface animations.

Main Results:

• Demonstrated a framework supporting interactive operations in a 6D observer space.
• Showcased enhanced visualization and analysis capabilities for 3D unsteady flows.
• Validated the 6+1D observer-based methodology on several 3D unsteady flow datasets.

Conclusions:
