Automatic path searching for interactive navigation support within virtual medical 3D objects

This article proposes the use of autonomous actors for navigation support within complex virtual medical objects reconstructed from Computed Tomography or Magnetic Resonance Imaging. Such objects are often maze-like. Therefore, users risk getting lost within them. We present synthetic vision-based actors capable of finding collision free paths from a given position to a goal point in most triangulated virtual environments containing loops and impasses. These paths are useful for guided flythroughs when performing non-invasive diagnostic tasks.
