ABSTRACT
In this study, we develop a non-photorealistic rendering expression technique that can be used in a real-time rendering environment based on the out-of-register concept, which is a type of accidental printing error. First, to develop the expression technique, out-of-register causes and cases were analyzed. We considered why the out-of-register concept was developed as a graphic element. Second, each characteristic was analyzed by examining cases of non-photo-realistic rendering expressions. The implementation method was realized through a linear algorithm without the use of machine learning, which is one of many methods. It is implemented through a linear algorithm for constant and predictable result values. Furthermore, we utilized algorithms and interfaces for effective expressions. We constructed and applied simple 3D cube shapes, characters, and virtual environments in a real-time rendering environment using the implemented expression method. Given that various forms of media are being produced in a real-time environment through expression methods, it is expected that this paper will help with the expression of the essential parts of things and applications of expression techniques when creating content.
