NGI Combustion Application

This paper explores IBR-Assisted Volume Rendering (IBR-AVR) techniques for remote and distributed visualization of large 3D datasets, such as time-varying volume data. By leveraging local and remote rendering strategies, we highlight the strengths and weaknesses of both approaches. The system allows for blending user-defined color and opacity, revealing intricate details in the data. Key considerations include the balance between interactivity and data transfer costs, and integrating traditional visualization methods to enhance the rendering experience.

Presentation Transcript

  1. NGI Combustion Application IBR-Assisted Volume Rendering for Remote and Distributed Visualization

  2. Volume Rendering • “True” 3D presentation of 3D data • Blending of user-defined color and opacity • Often reveals subtle details/structure in data

  3. Implementing Volume Rendering Two fundamental approaches • Render locally • Gain: interactivity • Cost: significant cost to move data from remote location • Render remotely • Gain: avoid cost of large data transfer • Loss: interactivity,

  4. IBR Assisted Volume Rendering 1. Subvolumes are composited together on remote host 2. Resulting images are sent to rendering engine 3. Use of 2D texture mapping hardware to achieve interactivity (limited rotation/motion parallax) 2. 3. 1.

  5. IBR Assisted Volume Rendering, ctd. SC99 Milestones: • Display of time varying volume data • Target data set size: 0.5TB Considerations • Inherent multiresolution “for free” from Combustion AMR • Render engine resolution scales with network bandwidth

  6. IBR Assisted Volume Rendering, ctd. Post-SC99 Considerations: • Feedback from renderer to compositing engine to accommodate motion parallax (the weak spot in IBR assisted volume rendering) • Combining volume rendering with traditional surface and glyph-based visualization techniques (combine volumes & geometry) • Adjust transmitted image size as a function of network parameters
