GPU-Based Large-Scale Volume Visualization

 Recent advances in high-resolution acquisition techniques (e.g., electron microscopy) let scientists acquire volume data of extremely large sizes. However, the tremendous resolution and the high complexity of these volumes present big challenges to storage, processing, visualization and visual analysis at interactive rates.

We work on developing scalable systems for interactive visual exploration and analysis of large (petavoxel) volumes resulting from high-throughput electron microscopy data streams. This project focuses on researching visualization-driven designs which restrict most computations to a small subset of the data. We employ a multiresolution virtual-memory architecture for better scalability than previous approaches and for handling incomplete data.
