Abstract
The 3DCG is the technology which has improved to making
photo realistic images. Meanwhile, toon shading is a technique in
3DCG that is used for the production work of the cel-touch 2D
animation. The purpose of the toon shading, it has been achieved
by discarding for generating photorealistic images. The toon
shading sometimes makes the wrong image by the difference of
the 3DCG images and the 2DCG images. The one of example on
the error occurs to with the light source in the condition of the
shade and the shadow on the animation character. The cel
animation images in order to consider the production efficiency,
shadow is adapted an always simple shape. For example, the
shadow produced by the toon shading, does not be made a
simple shapes shadows when the shape of the model is complex.
The purpose of this paper is how to set a light source for the
character such as cel animation when animator draw characters
by toon shading. Perform lighting for shooting live-action
characters in the same way, tried to cel animation about how
much closer the shadows.
