Perspective Exaggeration technique without Distorting the Faces of CG Characters in Video Games

Abstract

In recent years, CG works using toon rendering have become a common sight in video games and animation productions. These are one of the methods used to reproduce the characteristics of hand-drawn animation works in 3DCG. However, the accuracy of the model, which is a feature of 3DCG, may lead to a sense of discomfort and lack of dynamism when compared to hand-drawn animation. This method aims to express perspective exaggeration similar to that of hand-drawn animation by using the positional relationship between the model and camera to change the effect of perspective deformation, and by using real-time 3DCG to determine obstructions that hide the face and further deform the perspective exaggeration.
