Earthquake simulations generate large-scale ground-motion velocity wave-field data sets. One way to look at the data is to make it volume rendered so that researchers can examine the data efficiently. However, the volume data is usually quite large and a commodity graphics device can store one set of volume data. When the researcher need to look at the(More)
A typical LIDAR (Light Detection and Ranging) scan contains hundreds of millions of points. As such, the visualization of LIDAR point clouds poses a significant challenge in data analysis. One solution is to display LIDAR point clouds on a large display wall with an array of LCD monitors. This provides researchers with a high-resolution display environment(More)
Earthquake simulations generate large-scale ground-motion velocity data. However, in addition to the ground-motion velocity data, seismologists also need to study both ground-motion acceleration and ground-motion displacement data. Therefore, data post-processing is required to differentiate velocity data into acceleration data and to integrate velocity(More)
In numerical simulation of complex ows, it is important to identify diierent length scales of the ow and treat them diierently. In this report, we i n troduce a new multilevel scheme for simulating turbulent c hannel ows. Two diierent v ersions of the scheme, namely the spectral and nite diierence versions, are presented. The spectral version of the scheme(More)
