Anaglyph images are a type of stereoscopic image that creates a 3D effect when viewed with special glasses. These images are typically made by combining two photographs taken from slightly different angles, one tinted red and the other tinted cyan. When viewed through glasses with corresponding colored lenses, each eye sees a different image, which gives the illusion of depth. Anaglyph technology has been used in various media, including movies and video games, to enhance the visual experience. While it is a popular method for creating 3D visuals, it can sometimes cause color distortion, making it less ideal for certain applications compared to other 3D techniques like polarized 3D or active shutter 3D.
