    Automatic Generation of 3D Typography



    Three-dimensional typography (3D typography) refers to the arrangement of text in three-dimensional space. It injects vitality into the letters, thereby giving the viewer a strong impression that is hard to forget. These days, 3D typography plays an important role in daily life beyond the artistic design. It is easy to observe the 3D typography used in the 3D virtual space such as movie or games. Also it is used frequently in signboard or furniture design. Despite its noticeable strength, most of the 3D typography is generated by just a simple extrusion of flat 2D typography. Comparing with 2D typography, 3D typography is more difficult to generate in short time due to its high complexity.
    To the best of our knowledge, there has been no attempt to generate a 3D typography automatically. This paper introduces a method to design a 3D typography from given input letters automatically. We focus on the optical illusion technique to generate an object which shows different texts depending on the viewer’s perspective. We suggest a method satisfying two conditions: 1) it must create an 3D model which provides different contents in accordance with different perspectives and 2) the 3D model must have orthogonal projections which are identical with the corresponding shape of letters. Afterword, this paper applies the 3D typography to 3D CAPTCHA.
