Visualization Technique for Large-scale Data by Particle-based Volume Rendering

In analyzing and understanding complicated simulation results, it is useful to visualize large-scale data via volume rendering technique. However, volume rendering in existing remote visualization tools has server bottlenecks in the processing speed, the memory size and the data transfer. The proposed remote visualization system using Particle-Based Volume Rendering resolves these bottlenecks by converting large-scale volume data into small visualization particle data, and enables interactive remote visualization. Particle data processing on massively parallel supercomputers shows excellent strong scaling up to 1,000 cuncurrency, and data with 108 cells is processed in a few seconds.
