passive paper 3d glasses

Anaglyph images have seen a recent resurgence due to the presentation of images on the internet. Where traditionally, this has been a largely black & white format, recent digital camera and processing advances have brought very acceptable color images to the internet and DVD field. With the online availability of low cost paper glasses with improved red-cyan filters, and even better plastic framed glasses, the field is growing fast. Scientific images, where depth perception is useful, include the presentation of complex multi-dimensional data sets and stereographic images from (for example) the surface of Mars, but due to recent release of 3D DVDs, they are increasingly used for entertainment. Anaglyph images are much easier to view than either parallel sighting or crossed eye stereo grams, although the later types offer bright and accurate color rendering, which is not quite obtainable with even good color anaglyphs.
