Super deformed (SD) character is a style where characters have oversized heads and short limbs. The demand for SDcharacter is increasing as icons or stickers on communication tools have become popular. In this paper, we propose a systemto support producing a draft for SD characters. We collected illustrations of existing SD characters and classified them byshape and pose. The user can generate 3D super deformed model by choosing and adjusting body parts and pose using oursystem.

An ensemble cast is a method of dramatic production in which all members of the cast have equal amounts of screen timeand importance. The structure of the ensemble cast is complicated because it aims to emphasize the interconnectivity ofcharacters by unifying different parallel plot lines, and existing story support methods cannot be applied. In this paper, wepropose a system for supporting the scriptwriting with an ensemble cast. We analyze the existing movies with and withoutensemble cast to clarify the difference between them. Our system shows scene compositions extracted from existingmovies, which contains a given number of sub-stories and a given number of scenes. User experiments show that oursystem is useful for the scriptwriting with an ensemble cast.

Characters in visual contents are as important as the script in the initial production phase. A Design Engine was proposed to improve the efficiency of character development by providing aid in the planning phase, where character blueprints are drawn based on literal information provided by the producer. Many existing methods for creating color schemes cannot be applied to character design. We proposed a design method using a color scheme simulation system for one character at the time. This paper aims to provide a character color scheme support system using a color scheme scrapbook containing color palettes of existing characters. This is a part of the Design Engine for character making with literal information. The concept of a Digital Scrapbook is to set up a personal database in a computer that will help producers and directors to pin down the appearance or looks of the character they want their designers to sketch.

In this paper, we propose a method for realizing a polyhedral graph as a deltahedron, i.e., a polyhedron with congruent equilateral triangles as faces. Our experimental result shows that there are graphs that are not realizable as deltahedra. We provide an example of non-realizable graphs which are obtained by trying to construct deltahedra from each of the simple cubic polyhedral graphs with up to 10 vertices. We also show that the infinite families of non-realizable graphs can be obtained by solving the graph isomorphism problem.

Most manufacturing materials, such as wooden boards, metal sheets, and paper, are planar and nearly inextensible. Bending such materials not only allows us to form objects, but also avoids wastes and reduces gluing costs. However, the resulting shape is limited to developable surfaces. Due to this limitation, this method lacks flexibility in design. This problem can be addressed by adding slits to the materials, thereby allowing the conformation of a single sheet into expressive surfaces with high flexibility. In this paper, we propose an interactive design system for flexible geometry. A rectangular sheet material containing parallel slits is used in this work. The regions between the slits are called strips, and by bending them, we can simulate the desired shape. Both flexibility and geometric constraints are satisfied by a numerical optimization approach. The proposed system optimizes a bending shape of the strips by considering the smoothness of the surface and the user input. We show the effectiveness of our system using evaluation experiments.

In this paper, we propose a CAD system that supports drawing diagrams of flat-foldable origami pieces. Our system predicts possible folds that can occur in the current state of an origami piece and lists these candidates. This prediction is made based on the first four axioms of the Huzita-Hatori (Huzita-Justin) Axioms, a series of seven basic methods for folding a sheet of paper by referring to points and lines. All possible folding lines are generated by applying these axioms in our system, and then valley folded shapes are calculated and listed as candidates for the next step. When the user selects one of these candidates, the shape is automatically appended to the origami diagram as the latest step. We implemented this feature intending to reduce the cost of drawing diagrams. Our prediction feature is effective for easy origami pieces with a few folding steps, which aimed at the children and the beginners.

In general, characters in the video content has a great influence on the works they play a role in. The creation method in the pre-production still depends on the experience and sensitivity of the creators. For that reason, there is a problem of the communication-gap, and it is always created with the same members to avoid frequent occurrence such as re-take. The current state of video content creation education is often done by educators with experience of production, and it is done with empirical rules and sensitivity of each educator. Therefore, there are a lot of relatively technical education, education to solve production problems is very difficult. The authors have developed various proposal methods for the DREAM method. A literal template is a template that can summarize necessary information at the planning stage and can describe character settings and stories. The collage system is a system that makes it easy to create visual materials even for the creators who cannot draw pictures well. The lighting scrapbook and the camera work scrapbook is a camera work and lighting simulation system for planning the optimum lighting in the directing scheme. In addition to these, the authors have developed a system for the emotional expression, the color scheme and the modeling of characters. These various proposal methods are aimed at solving the communication gap in creation. In this research we report examples of using them as an educational tool for character making.

Direction is an important factor affecting the impression and quality of video contents. Therefore, the director must carefully decide the direction scheme. Especially unless the character’s emotions are directed effectively, viewers cannot empathize. Therefore, the director must carefully design the direction based on the theme and intention. Among them, lighting and composition are important factors directly affecting visual appearance. Therefore, careful design of lighting and composition is necessary. However, the direction depends on the experience and sense of the director. In other words, it is difficult to reuse the direction method and to preliminarily confirm the effect of the direction. Therefore, in this research, we focused on anger even in the character’s emotions. Furthermore, support to design of the composition and lighting for directing angry characters. In this research, we investigated and analyzed human anger. There are various causes and behaviors involved in anger. The impression to angry characters of viewer is varies depending on the causes of anger. Therefore, we classified each shots that angry character appears. This classification is based on the cause of anger. Furthermore, we analyzed lighting and composition of each shot. Based on these analysis results, we developed data library. In addition, we developed a template that can reproduce the lighting and composition of the analyzed shot with 3DCG. With this template, users can apply the lighting and composition of analyzed shots to arbitrary character models. It is possible to more effectively design the directing for angry character by using the proposed system.

Characters in visual contents are as important as the script in the visual contents production initial phase. Each character should have an attractive appearance, however, assigning different characteristic is not easy. Previous methods for the color scheme design cannot be applied to the character design. In this paper, we proposed a character color simulation system with a color scheme scrapbook. Our color scheme scrapbook contains sets of color palette extracted from existing character groups. Users input line drawings of their original characters and then specify regions of body parts. A desired set of color palette in the scrapbook can be applied to them.

A crucial part of creating movies, but also games, is the usage of camera work. After creating a story that is to be conveyed to the audience it should also be presented in a way that will make them feel the way that was intended. This can be done in a number of ways such as sounds and effects but even if the effects were to be the same there would be a great difference in affect if it was to be seen from a long distance or close up. The purpose of this study is to analyse the camera work in horror movies and find trends that can later be used to reproduce camera work automatically in digital contents.

Robot anime is one of the most popular genres in Japanese anime, and it is very popular in all around the world. In this study, we have focused on "battle scenes", a popular characteristic which is usually composed by large number of shots showing robots actions, power, speed and so on. The purpose of this study is to create a supporting system, which include camera blocking for when producing battle scenes. In this research, we have analyzed robots' common actions with the characteristic of camera blocking from existing robot anime, organized the screen structure that characterizes robot anime, and we were able to found out the trending of these works. After doing so, we were able to create a supporting system for camera blocking for when producing robot anime's battle scenes using the data found in this research. The support system also shows reference information for producing structure or shot design for battle scenes.

In this paper, we propose a support system of color correction and replacement from user collected digital images semi-automatically. This system works in three steps. First, it calculates the histograms of HSV data from user collecting digital images. These histograms that can be interpret as a "user preference" act as a color filter. Second, it calculates a set of histograms from one image which user inputs into it to want to modify the part of colors. Simultaneously, the resemble data are selected by histogram intersection from phase 1. Third, the system replaces or corrects the colors in the target image. As a result, users can correct the color of image by the "implicit" preference.
