APPLICATION OF 3D ANAGLYPH TECHNOLOGIES IN GEOLOGIC AND GEOGRAPHIC EDUCATION

The Department of Geosciences at NDSU is utilizing 3D anaglyph technologies to enhance its educational programs in geology and geography.
Aside from specialized web-based images produced for statewide and nationwide outreach, regular use of anaglyphs is made within the classroom. Because the anaglyphs can be printed directly as posters, no special classroom projection equipment is really necessary. We provide classroom sets of red/blue 3D glasses, which our students utilize in viewing 3D topographic imagery, whether it be delivered via poster or the web.

NDSU'S program of integrating anaglyphs into geoscience education is made possible through a cooperative effort with Ray Sterner of the Applied Physics Laboratory, Johns Hopkins University. The anaglyphs were made using the IDL computer language on an HP workstation. Digital Elevation Model (DEM) data, freely available on the USGS web site, were used for the images.

3D anaglyph of eastern New Mexico, northwestern Texas. Included is the area of White Sands National Monument and Guadalupe Mountains National Park, Click on the image for an enlargement (560K). Use red/blue 3D glasses to view.
	NDSU geology professor, Donald Schwert, lecturing on glacial topography utilizing large-scale posters of 3D anaglyphs. Even subtle landform features are visible using this technology. Anaglyphs can be shown as projected web images, as slides, or as posters.
Students using anaglyph products in classroom. Students at all levels enjoy working with the 3D imagery, for it emphasizes topographic expression and enhances synthesis of landform relationships.
	3D anaglyph of the San Rafael Swell, east-central Utah. This great anticlinal uplift is roughly 75 miles long and 30 miles wide. The east side is flanked by a spectacular east-dipping monocline of Triassic and Jurassic sandstone beds. Click on the image for an enlargement (590K). Use red/blue 3D glasses to view.
3D anaglyphs can be viewed by large audiences, either by poster or by video or slide projection. The red/blue glasses are inexpensive (see links below). Simply instruct the audience to wear the RED lens over the left eye.
	3D anaglyph of glacially-modified topography associated with the Prairie Coteau, SD, ND, MN. During the last (Wisconsinan) glaciation, this landform divided southward-flowing into two lobes: the James Lobe to the west, and the Des Moines Lobe to the east.
