In this paper, we present an interactive 3D character modeling and animation including a data management tool for editing the animation. It includes an animation editor for changing animation sequences according to the modified structure of 3D object in the object structure editor. The animation tool has the feature that it can produce motion data independently of any modeling tool including our modeling tool. Differently from conventional 3D graphics tools that model objects based on geometrically calculated data, our tool models 3D geometric and animation data by approximating to the real object using 2D image interactively. There are some applications that do not need precise representation, but an easier way to obtain an approximated model looking similar to the real object. Our tool is appropriate for such applications. This paper has focused on the data management for enhancing the automatin and convenience when editing a motion or when mapping a motion to the other character.

In this paper, we developed an interactive animation authoring tool and developed the Android based interactive edutainment contents. The authoring tool for creating interactive animations developed in this paper is based on a graphical user interface, so users can easily create interactive animations. Interactive animation contents created by this authoring tool can be created as images and xml files so that they can be used directly on mobile devices. In order to increase learning efficiency for children, Android-based interactive edutainment electronic storybooks, which is implemented using this authoring tool, provided a recording function to listen to the parents' voice as well as an interactive action in which the characters move in accordance with the story line. We also provided a STEAM game that combines creativity and imagination with creative science and technology. Therefore, by creating the edutainment contents through the proposed authoring tool for interactive animation, various interactive animation contents could be produced more easily than the code implementation method. Through this study, I hope that it will be helpful for the development of various interactive edutainment contents to provide educational contents considering the quantity and quality to infants.

Today, one of the most important reasons that 3D software becomes a core part of the essential tools in the video contents field like the movies, animation, CF, motion graphic, games and etc. is that they can save budget of contents makings and can produce better effects than conventional methods like miniature, matt painting, extra mobilization and etc. and can save time and have the merit that they are not limited in space. In this paper, I analyzed IK(Inverse kinematics) system characteristics for the efficient education of 3D character animation particularly most used of 3D applications which is now supposed to be nearly necessary elements in game, animation, movie and contents. And by analyzing merits and demerits of each tool on Bone, Character studio and Character Animation Toolkit, systems which are most used practically in the various Inverse kinematics tools, I showed the result of analyses about the fact that educating which of the above three Inverse Kinematics tools is helpful and beneficial for the students for the efficient education in the university where should teach much in the limited time

Animation tool has been made changes rapid development of animation from analog tool to digital authoring tool. Depending on the change in the status of digital authoring tools, education of digital authoring tool has brought many changes occurred in the institute and university. Digital authoring tool was insufficient for research of authoring tool due to the recognition that authoring tool is a simple tool. I try to resolve the difficulties through the analysis digital authoring tools to students studying at the university. In addition, Suggests social/cultural change of animation practitioners and effective training methods of digital authoring tools in the education of beginners and practitioners. This tool have perceptual knowledge and narrative knowledge. Since the language features and knowledge features is difficult to learn. it must be learned knowledge of computer graphics of professional level properly to learn. Then users should try to be creative within the authoring tool to produce creative results. also formed the community and to exchange information for self-development further it should form job market that authoring tool make formed through medium. So, I think that there is a need to change academically attitude to authoring tool. because this is not only the positive side but it occurs phenomenon to enslave users in authoring tool, and blind faith in the authoring tool or critical stance on software. It was a lot of pre-existing research that investigate engineering and industrial side in the authoring tool. Through this thesis, We will find social/cultural features and academic significance, and investigate that how to approach the method of education.

Technology in the animation industry has evolved significantly over the past decade. The tools to create animation are becoming more intuitive to use. Animators now spend more time on the artistic quality of their work than wasting time figuring out how to use the software that they rely on. However, one particular tool that is still unintuitive for animators is the motion graph editor. A motion graph editor is a tool to manipulate the interpolation of the movements generated by the software. Although the motion graph editor contains a lot of options to control the outcome of the animation, the emotional rhythm of the movements desired by the animator still depends on the animator's skill, which requires a very steep learning curve. More often than not, animators had to resort to trial and error methods to achieve good results. This inevitably leads to slow productivity, susceptible to mistakes, and waste of resources. This research will study the connection between the motion graph profile and the emotions they portray in movements. The findings will hopefully be able to provide animators reference materials to achieve the emotional animation they need with less effort.

In this paper we describe the method of controlling the animation of 3D characters according to ISO/IEC 19774 (H-Anim) specification, which has been released by Wed3D Consortium and ISO/IEC SC24 WG6. The animation structure of the H-Anim character can be defined and modified in our H-Anim editor program. Our H-Anim animator generates the character's motion automatically according to the input of motion parameters at the character's joints interactively. This paper is focused on the development of a motion generation tool for human-like characters defined by H-Anim structures.

Numerous studies have attempted to present converting 2D drawings to 3D. However, converting 3D shapes to exactly how a person thinks is challenging because 2D drawings include numerous variables and possibilities. This study focuses on visualizing 2D to 3D in a commonly used 3D animation software required in animation education or the 3D industry. We implemented our SketchTo3D tool to add the editing and automatic texture assigning method from the imported 2D image into the 3D software that previously had to be done manually. As a result, the SketchTo3D tool saves time to immediately visualize the composition, shape, and volume to express the 3D character, providing an opportunity to break down the barrier between 2D and 3D.

Walt Disney Feature Animation released high quality films such as 'Frozen', 'Big Hero 6', 'Wreck-it Ralph', 'Zootopia', 'Moana', 'Frozen 2' and not only got high score in box office but showed great CG and visuals. However, making feature animation requires a lot of time, money, and efforts so it is very important to support studios' artists to finish each show within limited budget and time. This paper shows artists' training program such as 'Short Circuit' and 'Bootcamp' that walt disney feature animation provides their artists to improve their creativity and do their jobs artistically and efficiently. Disney's training program not only provides artists various training classes but gives them chances to work on short animation which enhances artistic skills and enable them to work in different departments and experience different tasks. This paper also explains some training cases of CG studios in South Korea and Disney Animations' in-house tools.
