IntroductionMultiresolution Volume Rendering

• Visualize large data set
• Render the high-priority regions with highest
  accuracy, while lower-priority regions are
  rendered with progressively less accuracy

Research direction (1)

• Video based compression for time-varying volume
  data. (multiresolution, for large data set)
• Motion compensation across different nodes/levels
• Must keep previous I-frame or P-frame to decode
  the next frame
