    Anime characters often take the shape of deformed vehicles. However, it is often difficult for a director to convey his/her vision of character deformation to the designers through textual documents − which is the standard format by which they communicate. A communication gap forms where the designer cannot fully understand what the director has in mind, which subsequently leads to inefficiency and time loss during the design process. Our aim is to improve design efficiency for deformed vehicle characters. In this study, the vehicle we focused on was airplanes. We measured and compared the size and proportion of the different parts of airplanes and existing airplane-based characters. We summarized the data gathered into a deformation template, which we implemented into 3Ds max along with a simple deformation simulation system. As a result, we were able to perform deformation based on the deformation template in a semi-automatic matter. A questionnaire based evaluation showed that our system is indeed effective in designing characters.

    Sewing in homemaking education aims to nurture technical and creative ability of children. Design of original handicrafts requires the construction of an appropriate 2D pattern, but this is very difficult for children and this restricts them to use off-theshelf 2D patterns only. Many schools have introduced CAI (Computer Assisted Instruction) today, but they are not useful for learning creative ability because they are merely used to show images and movies. We therefore developed handicrafts design support systems for novices to design their own original3D handmade crafts. This paper examines the requirements these systems should satisfy to be used as digital education tools in homemaking education. We successfully demonstrated in workshops and user studies that children can design original handicrafts using our design support systems. These case studies show that homemaking classes can teach creative ability, fun of sewing, and versatility of computers.

    The dawn of perspective can trace back to the achievements by Craftsmen of the 16th century in southern Germany. German Craftsmen after the death of A. Durer are succeeding a perspective that used by artists and architects of the fifteenth century in Italy. H. Lencker, L. Stoer, and W. Jamnitzer who are German Craftsmen have published pattern-books. In this study, we focus on pattern-books by German Craftsmen, we consider construction method for Craftsmen early 16th century in southern Germany, and compared with French-Italian drawing method. As a result, the south German Craftsmen who are combination of three.dimensional polyhedral shapes (figurative solid) used to represent the perspective. On the other hand, we conclude that mathematicians and artists in France and Italy the same period was not a representation of three-dimensional shapes. And we consider that they assume the space outside three-dimensional shape, set the space-grid, and accurately represent threedimensional shapes.
