A study of real time pseudo afterimages using 3DCG

Abstract

In conventional hand drawing animation, “Cartoon Blur”, a non-photorealistic motion blur is used in order to emphasis a character motion. In previous researches, cartoon blur is divided into three types : Lines, After-Images, and Deformation. Beside three types of cartoon blur, there is another type of cartoon blur which also widely used in cel-animation. This kind of cartoon blur is a phenomenon of surfaces’ colors remain as trace of their motion then combine at further distance. We named the phenomenon as “Pseudo Afterimage”, and propose method to express it in real time 3DCG.
