概要	In two-dimensional (2D) animation, the thickness of object outlines and contour lines is often varied to emphasize or exaggerate the shape of the object. Adding a 2D touch to three-dimensional computer graphics (3DCG) animation using toon-rendering is common, but existing techniques cannot achieve varying line thickness. This paper proposes a method of recreating the effect of varying the outline and contour line thicknesses based on the object shape in real-time 3D environments such as video games. Our method focuses on exaggerating the thickness of lines where the target polygon is curved. Furthermore, by using a backface polygon of the target polygon, we are able to create a continuous outline of the object, thus recreating a closed outline of the object with varying line thickness.
