Anaglyph is a type of 3D imaging that uses two different colored images to create a stereoscopic 3D effect. The term comes from the Greek words 'ANA' and 'glypho, ' meaning 'to carve again.' The most common type of anaglyph is red-cyan, where one image is filtered with a red filter and the other with a cyan filter. The CAMEO 5 letter solution refers to the CAMEO 3D glasses, which are used to view anaglyphs.
