      We describe a system for the texture-based direct volume visualization of large data sets on a PC cluster equipped with GPUs. The data is partitioned into volume bricks in object space, and the intermediate images are ...
    • High-Fidelity Rendering of Animations on the Grid: A Case Study 

      Aggarwal, Vibhor; Chalmers, Alan; Debattista, Kurt (The Eurographics Association, 2008)
      Generation of physically-based rendered animations is a computationally expensive process, often taking many hours to complete. Parallel rendering, on shared memory machines and small to medium clusters, is often em- ployed ...
