GPU-Accelerated Volumetric Raycasting of Cloud Data

Mayank Singh created an OpenGL/GLSL application for viewing volumetric cloud data using either the CPU or GPU. Volumes were created using isosurfaces and raycasting.

Bathymetry data, 90-East Ridge, Indian Ocean

This VTK/Python program is an exploration of the geoid and bathymetry data gathered by Texas A&M University of the Ninteyeast Ridge, in the Indian Ocean. The visualization was created by Christopher Paul from Oceanography.

Ion Thruster Plasma Flow

This VTK data is a 400-second animation of the plasma flow resulting from an ion thruster unaffected by magnetic interference. The visualization was created with Rachel Vannelli from Aerospace Engineering.

Pointe du Hoc Terrain Visualization

This ParaView visualization is of Pointe du Hoc, one of the more important battles of D-Day and a popular tourist attraction. The area was captured through a synthesis of laser scanning and digital images. This visualization is part of the American Battle Monuments Commission's project to preserve this and other historic sites. The project was the work of R.B. Warden, R. Burt, J-L Briaud, and M. Everett. The visualization ws created by Christine Liu.

Sinopec Large Oil Field Extraction Data

This large ParaView visualization was a collaboration between the Institute for Scientific Computation and Sinopec designed to show large-scale oil field simulations. The IVC was chosen as the display venue for its collaborative capabilities.

Grid Roughening

Dr. Steve Johnson brought his dissertation into VTK for visual analysis. The dissertation involved taking a regular atomic lattice and stressing it slightly. This stress creates irregularities while keeping the same overall structure intact.

Ocean Floor Mapping

The Visualization Toolkit, or VTK, was used to create this visualization of a portion of the ocean floor. Satellite data created the backdrop for the floor, upon which was overlaid high-resolution data collected by Texas A&M's Oceanography department. Distortions of the ocean's surface are shown at the top of the image. Chris Paul created this visualization.

Andy Gump Landslide, Grand Mesa, Colorado

Netra Regmi, Working under Dr. Giardino of Texas A&M's Geosciences department, developed a methodology of reconstructing a slope condition before failure and visualizing the failure mechanism in three dimensions by using GIS and GPS elevation data before and after slope failure. The data was then converted into VTK format and displayed using ParaView.

Aquifers

The IVC obtained data from the Texas Water Development Board on aquifers in various parts of the state. We took that data and converted it into VTK format for easy visualization.

Trees

As part of the Knowledge Engineering Lab's long-term forestry visualization project, Dr. Andrew Birt's research group came in with some data regarding forests changing over time, and we worked on ways to effectively visualize this data, including using different representational models for each tree class.

Ants

In August of 1960, entomologists headed by Dr. John Moser excavated a large Leaf Cutter Ant (Atta Texana) nest. All data was manually plotted and recorded by hand. With the new technology available, Dr. Moser allowed Texas A&M to revisit the data set, first converting the cavity locations from the hand drawings to digital maps. These were then composited in 3D to create a visualization of the inner workings of the nest.

Groundwater Contaminant Flow

This OpenDX program illustrates how a contaminant flows through groundwater over time. The data was generated using c-us3d, a groundwater flow and contaminant transport simulator created by M. Celia and Z. Leyk in 1997.

Ground Penetrating Radar Data

This OpenDX program visualilzes ground penetrating radar data profiles. The data was collected by John Degenhardt and Will Jorgensen in 2005.
