Abstract
There are an almost unlimited number of ways to produce and view stereo images. One of the simplest and least expensive is anaglyph (red/blue) stereoscopy. Stereo vision is produced by combining two images produced from slightly different points-of-view. These images are filtered to remove red or blue and green before being combined them into a single stereo image. We have applied this technique to a wide variety of models created from the Visible Human Project data. The depth information obtained from these images has demonstrated the value of this technique in the teaching of anatomy.

Keywords: stereo vision, 3D anatomical models, teaching of anatomy.
