    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.

    Mistakes can be observed in the three.dimensional projections drawn by students during the early stages of their study of technical drawing. It is considered that certain students, despite their understanding of what projections mean and what they express, have difficulties in perceiving and drawing three. dimensional projections correctly. In order to draw such a projection, it is necessary to visualize a form that does not exist, and to imagine what such form looks like when seen from a different angle. It is difficult to discover whether there are errors involved in this process as it takes place in students’ heads, and it is difficult for them to realize their own mistakes. Therefore, in this research a study was carried out involving the introduction of the study of metacognitive skills into technical drawing classes in order that students are able to observe their actions in an objective manner. The study of metacognitive skills is chiefly used in sports and similar fields. After one week studying metacognitive skills, it was observed that the way the subjects drew figures changed to a certain extent. Based on this, it is thought that study employing metacognition may well have an effect to an extent on education in the drawing of figures.
