Mammoth Calf Lyuba On Display
On Nov. 17th-19th the Duderstadt Center’s Visualization Expert, Ted Hall, will be in Austin, Texas representing the Duderstadt Center at SC15, a super computing event. The technology on display will allow people in Austin to be projected into the MIDEN, the University of Michigan’s immersive virtual reality cave, allowing visitors in both Ann Arbor and in Austin to explore the body of a mummified mammoth.
The mammoth in question is a calf called Lyuba, found in Siberia in 2007 after being preserved underground for 50,000 years. This specimen is considered the best preserved mammoth mummy in the world, and is currently on display in the Shemanovskiy Museum and Exhibition Center in Salekhard, Russia.
University of Michigan Professor Daniel Fisher and his colleagues at the University of Michigan Museum of Paleontology arranged to have the mummy scanned using X-Ray computed tomography in Ford Motor Company’s Nondestructive Evaluation Laboratory. Adam Rountrey then applied a color map to the density data to reveal the internal anatomical structures.
The Duderstadt Center got this data as an image stack for interactive volumetric visualization. The stack comprises 1,132 JPEG image slices with 762×700 pixel resolution per slice. Each of the resulting voxels is 1mm cubed.
When this data is brought into the Duderstadt Center’s Jugular software, the user can interactively slice through the mammoth’s total volume by manipulating a series of hexagonal planes, revealing the internal structure. In the MIDEN, the user can explore the mammoth in the same way while the mammoth appears to exist in front of them in three virtual dimensions. The MIDEN’s Virtual Cadaver used a similar process.
For the demo at SC15, users in Texas can occupy the same virtual space as another user in Ann Arbor’s MIDEN. Via a Kinect sensor in Austin, a 3D mesh of the user will be projected into the MIDEN alongside Lyuba allowing for simultaneous interaction and exploration of the data.
Showings will take place in the MIDEN
