Abstract
Abstract A bare eyed stereogram based on continuous tone, non-random dot art and a process for making the stereogram. A computer implemented process for making the stereogram uses a computer system having a central processing unit, memory, storage, a user interface, an edit program and display means. The art is input to the system in the form of repeating bands of picture elements in a stereogram base. The picture elements have assigned information, and depth information as well. Below a threshold value, new information is assigned by the method of smear. At or above the threshold value, information is provided by a number of techniques which import the information values of picture elements outside the stereogram base. Preferably some of the information is color information and the external color information values are altered to blend with colors in the surrounding base. A process for making a stereogram with wide repeating bands that can be viewed at a distance is shown. A stepping procedure for creating stereograms and a method of superimposing multiple stereograms is shown.
