“…At the 2007 IEEE Visualization and the AGU 2007 conferences in California, University of Minnesota researchers demonstrated how an OQO computer, small enough to be held in a single human hand, is used to interact with live 3D mantle convection data computed at Minnesota (Damon et al 2008;Yuen et al 2007). Observers at the demonstration were able to use the OQO computer to manipulate the computed output data.…”

“…A possible solution may be to interrogate interactively and visualize the solution while it is running, thus saving a lot of post-processing time and also time in writing the data to disk space. Recently, researchers at the University of Minnesota working in an interactive visualization mode now have the ability to analyze and manipulate large sets of scientific data from real-time mantle convection simulations in Cartesian coordinates (Damon et al 2008). In our previous work (Damon et al 2008), we have shown that the availability of hundreds of processors coupled with high speed networks at 10 Gbits/s and advanced volume rendering systems (Porter 2002, Porter et al 2002) enables a faster analysis of numerical data, increased levels of research productivity and a substantial reduction in archiving resources.…”

“…One reason for writing this paper is to make some clarifications to our previous work (Damon et al 2008) by giving more technical details and illustrations and to introduce some of the recent implementation we made in using hand-held devices, especially in web-portal and building AJAX web applications. We will also bring in a new data set involving spherical coordinates in addition to the previously shown Cartesian coordinates.…”

Ubiquitous interactive visualization of 3D mantle convection using a web-portal with Java and Ajax framework

We have developed a new strategy and espouse a novel paradigm for large-scale computing and real-time interactive visualization. This philosophy calls for intense interactive sessions for a couple of hours at a time at the expense of storing data on many disk drives during regular or heroic runs on massively parallel systems. We have already carried out successfully real-time volume-rendering visualization by employing hundreds of processors for a grid with over 25 million unknowns. Both Cartesian and spherical 3D mantle convection are visualized. The volume-rendered images are viewed on a large display device, with many panels holding around 13 million pixels. We will employ a software strategy involving an hierarchical rendering service, which will have as software an Ajax interface for interactive visualization of large data sets on many different platforms from desktop PC's to hand-held devices, such as the OQO and the Nokia N-800. An option for stereo viewing is also implemented. We have installed a user interface as web application, using Java and Ajax framework in order to achieve over the Internet reasonable accessibility to our ongoing runs. Our goal is to expand the array of interactive devices, which will make it feasible to carry out ubiquitous visualization and monitoring of largescale simulations or onsite events and to allow for collaborations across oceans.

Volume rendering visualization of 3D spherical mantle convection with an unstructured mesh

et al. 2008

We propose a new approach to utilize the algorithm of hardware-assisted visibility sorting (HAVS) in the 3D volume rendering of spherical mantle convection simulation results over unstructured grid configurations. We will also share our experience in using three different spherical convection codes and then taking full advantages of the enhanced efficiency of visualization techniques, which are based on the HAVS techniques and related transfer functions. The transfer function is a powerful tool designed specifically for editing and exploring large-scale datasets coming from numerical computation for a given environmental setting, and generates hierarchical data structures, which will be used in the future for fast access of GPU visualization facilities. This method will meet the coming urgent needs of real-time visualization of 3D mantle convection, by avoiding the demands of huge amount of I/O space and intensive network traffic over distributed parallel terascale or petascale architecture.

Increasing volumes of digital data, combined with advances in visualization, allow for a new three‐dimensional (3D) conceptualization of modern subduction systems. Here we present 16 visual exploration sessions with the ShowEarthModel program that interrogate modern slab morphologies on Earth. These virtual voyages through the Earth's interior provide a snapshot into the four‐dimensional evolution of plate tectonics, captured by the modern state of slab structure. Examining the modern subduction system in an interactive 3‐D framework provides an improved conceptualization of the morphology of slabs. The movies demonstrate that unlike the modern mid‐ocean ridge system, modern subduction systems are laterally discontinuous features, making lateral slab edges prevalent. The 3‐D visualizations elucidate the manner in which slabs intersect and overlap, processes that occur in at least six of the Earth's major subduction zones. The observed variability within a given subduction zone as well as the physical presence of intersecting slabs suggests that slab gaps and slab windows are common. The 3‐D rendering shows relative differences in the radius of curvature for arcuate slabs, as well as the variability in dip within a given subduction zone. Addressing the complex geometries of subducted lithosphere in this way can place constraints on outstanding questions of subduction dynamics including slab strength, mantle rheology, mantle flow circulation, and plate‐asthenosphere coupling. By conceptualizing the modern subduction system on Earth in 3‐D space, this paper contributes to the paradigm shift from a two‐dimensional (2‐D) to 3‐D framework for interpreting the subduction process.
