Animation Image Education Technique in Cartoon Film Production

摘要

I introduce an expert skill education technique about unique 'movement impression' The impression is an expert skill method and it is very important for education of animation production. The reason is a non-linear element as 'mental motion' exists in a human sense of an eye. Mental motion is not a physical motion, but is felt be real by audience. I put some examples as a kind of 'mental motion'. Each element which constitutes an animation is an exaggeration and transformation of an object that is in a perspective of an object, a timing of movement of a character and a change of acceleration when an object moves. It is an important element in the education making up in an animation production that is understanding about exaggerations of volume and time about the increase and decrease of volume deformation. Education technique is training for an animator on the basis of conventional repeated practice, which is able to understand these elements sensuously. But it was difficult to let them study it from a principle numerically and effectively. Education technique to suggest on this paper, I do the non-linear function that an animation picture has in form to be able to see numerically and to let them understand it from a principle. I explain an execution procedure of this method. The students extract frame data from an existing animation work. They pull out only an existing character part in data. They extract movement of a character with two dimensions virtual bone and, from an appearance of a character, divide a movement ingredient of the character. They build virtual three dimensions bone in the cause with two dimensions bone that they made it. They cover three dimensions bone that made it with a character set with an original image as skin. They compose Three dimensions of animations made by such a procedure and two dimensions of original animations. They extract difference movement part data of a three dimensions character and a two dimensions character from a made animation. They understand the characteristic that each data have from extracted difference part data. It becomes easy for a student that non-linear shape transformation and a change of a movement timing let they understand an existing thing in movement of a character of two dimensions animations by going through a procedure of this technique. It surely need a lot of time to execute this method. But, the students get possible to control time to need in understanding briefly so that they are different from a training method on the basis of conventional repeated practice, and there is an element of digitalization of a principle. In addition, what relation of bone and skin can understand that is made as an education effect by enforcement of repeat training.
