Generation of three-dimensional typography for multiple texts

Abstract

Three-dimensional typography refers to the arrangement of text in three-dimensional space. It injects vitality into the letters, thereby it gives the viewer a strong impression that is hard to forget. Three-dimensional typography also satisfies legibility as well as aesthetic needs. Despite its noticeable strength, most of the three-dimensional typography is generated by just a simple extrusion of flat 2D typography. Comparing with two-dimensional typography, three-dimensional typography is more difficult to generate in short time due to its high complexity. This thesis introduces a method to design the three-dimensional typography from given input strings 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 object which provides different contents in accordance with different perspectives and 2) the object must have orthogonal projections of an object which is identical with the corresponding shape of letters. Afterword, this thesis discusses two applications of three-dimensional typography: 3D CAPTCHA and 3D printable typography.
