教育番組で使用されるCGの効果的描画技法に関する研究

抄録

In three-dimensional CG animation, the photographic reality of objects can be changed freely by changing the drawing method. When using solid figures as mathematics teaching materials, designers have to consider their reality. In the present research, we conducted two types of experiments in which figure recognition was examined according to difference of reality. In experiment 1, the task of recognizing signs on the surfaces of hexahedrons drawn by three methods was given to the subjects. The result shows that a realistic. In experiment 2, the task of recognizing signs on the surfaces of octahedrons drawn by three methods was given to subjects. Results are the same as in experiment 1, with an additional practice effect. These results indicate that (1) a higher degree of reality is not always necessary (2) designers must consider learners' characteristics in designing teaching materials.
