Developing Virtual Reality Visualizations for Unsteady Flow Analysis of Dinosaur Track Formation using Scientific...

Area of Science:

• Paleontology
• Computer Science
• Scientific Visualization

Background:

• Analyzing dinosaur track formation requires understanding complex interactions between foot movement and substrate deformation.
• Existing visualization methods may not fully capture the dynamic processes involved in ichnology.

Purpose of the Study:

• To develop novel virtual reality (VR) flow visualization tools for analyzing dinosaur track creation.
• To apply the Scientific Sketching methodology in a large-scale project for developing visualization tools.

Main Methods:

• Utilized Scientific Sketching, integrating input from artists, visualization experts, and paleontologists.
• Employed an iterative design process involving art and computer science students in rapid visualization sketching cycles.
• Incorporated paleontologist feedback through multiple critique sessions to refine visualization concepts.

Main Results:

• Developed effective VR visualization methods, including particle, pathline, and time surface visualizations.
• Introduced visual metaphors, such as pathsurfaces, to compare foot motion and substrate deformation.
• Gained insights into the relationship between dinosaur foot movements and substrate deformations.

Conclusions:

• Scientific Sketching is a viable methodology for developing specialized scientific visualization tools.
• The developed VR tools offer paleontologists enhanced capabilities for analyzing dinosaur track data.
• The project highlights the evolution of research questions through collaborative design and prototyping.
