It seems like that the main stream of animation for theaters transferred from cells to 30 animations. It can be easily seen if current situation is compared to the time when al! works were Cell animations. Although earlier papers were mostly about studies on Cell animation works, future studies will publish papers related to 30. Accordingly, this study studied the association of the researcher's paper with 30 works while It had been applied to 20. Then, based on the data, this study analyzed how major/supporting characters were transformed to animation characters in the scenes that were animated at the beginning and end of film that were reieased in 2007. This result was compared with the character made using a voice actor in the Pixar's long piece of animation for theater that had been already screened. The data were made into values to some extent in an attempt to increase satisfaction in the result of analysis comparing the character with the voice actor. When making characters using actual persons, it is hoped that grasping the modeling factors of the images making 20/30 characters as indicated in this study will be helpful in producing animation characters.

Virtual Reality makes a virtual environment more realistic and, furthermore, it provides a variety of experiences which we cannot have in reality. A drastic growth of GPU performance and increase of computing capability make virtual environment more realistic than ever. One important element of constructing virtual environment is to animate 3D characters. Many researchers have been studying 3D characters animating and a myriad of methods have been proposed to make them more realistic. In this paper, we discuss the technologies and characteristics of 3D character animation. We believe that realistic characters in Virtual Reality will be applied to various fields: education, film and game industry, business and, particularly, medical area such as telemedicine, virtual surgery, etc.

There has been some research into a speech system for communications between those who are hearing impaired and those who hear normally, but the system has been pursued in inefficient teaching ways in which existing teachers teach each individual due to social indifference and a lack of marketability. In order to overcome such a weakness, there appeared to be a need to develop contents utilizing 3D animation and digital technology. For the investigation of a standard face and a standard spherical shape for the preparation of a character, the study collected sufficient data concerning students in the third-sixth grades in elementary schools in Seoul and Gyeonggi, Korea, and drew up standards for a face and a spherical shape of such students. This data is not merely the basic data of content development for the hearing impaired, but it can also offer a standard measurement and a standard type realistically applicable to them. As a system for understanding conversations by applying 3D character animation and educating self-expression, the character speech animation system supports effective learning for language education for hearing impaired children who need language education within their families and in special education institutions with the combination of 3D technology and motion capture.

In this paper, we implemented cyber character that can do speech recognition, speech synthesis, Motion tracking and 3D animation. For speech recognition, we used Discrete-HMM algorithm with K-means 128 level vector quantization and MFCC feature vector. For speech synthesis, we used demi-syllables TD-PSOLA algorithm. For PC based Motion tracking, we present Fast Optical Flow like Method. And for animating 3D model, we used vertex interpolation with DirectSD retained mode. Finally, we implemented cyber character integrated above systems, which game calculating by the multiplication table with user and the cyber character always look at user using of Motion tracking system.

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.

Traditional rendering of cartoon character cannot revive the feeling of concept drawings properly. In this paper, we propose capture technology to get toon shading model from the concept drawings and with this technique, we provide a new novel system to render 3D cartoon character. Benefits of this system is to cartoonize the 3D character according to saliency to emphasize the form of 3D character and further support the sketch-based user interface for artists to edit shading by post-production. For this, we generate texture automatically by RGB color sorting algorithm to analyze color distribution and rates of selected region. In the cartoon rendering process, we use saliency as a measure to determine visual importance of each area of 3d mesh and we provide a novel cartoon rendering algorithm based on the saliency of 3D mesh. For the fine adjustments of shading style, we propose a user interface that allow the artists to freely add and delete shading to a 3D model. Finally, this paper shows the usefulness of the proposed system through user evaluation.

This study analyzes into the characteristic appearance in distintion with emotional changes toward visual forms of psychology along with character development in the 3D animation industry. In this regard, the study seeks to propose essential targets of the five emotional characters from the Pixar's animation Inside-Out to prove psychological effects to the character's visual appearance. As a previous research, the study analysis the visual representations oriented toward both emotional facial expression and emotional color expression using both Paul Ekman and Robert Plutchik's human basic emotion research. The purpose of this study is to present the visual guideline of emotional character's appearance through the various human expression for differentiated character development in animation production.

We present a method for transferring deformation weights of a human character to three-dimensional (3D) scanned clothes. First, clothing vertices are projected onto a character skin. Their deformation weights are determined from the barycentric coordinates of the projection points. For more complicated parts, such as shoulders and armpits, continuously moving planes are constructed and employed as projection reference planes. Clothing vertices on a plane are projected onto the intersection curve of the plane with a character skin to achieve a smooth weight transfer. The proposed method produces an initial deformation for physically based clothing simulations. We demonstrated the effectiveness of our method through several deformation results for 3D scanned clothes.

Game program had been classed by 3D or on-line game etc, and engine and game programming simply, But, game programmer's kind more classified new, Artifical Intelligence game programmer's role is important. This paper makes game character study and moved by intelligence using reinforcement learning algorithm. Fought with character enemy using developed game, Confirmed whether embodied game character is facile by intelligence, As result of an experiment, we know, studied character defends excellently than randomly moved character.

Now a day, lots of the animations include TV series Animations are made by the technique of 3D Animation. However, 3D Animation obstructs visual elements and deteriorates an acquaintance with the limit of unfamiliar material methods and dispersion of light. For this reason, a large of number of 3D Animations are repacked with the style of 2D Animation. Most of previous studies for the conversion of output 3D Animation to the style of 2D Animation are analysis for 2D rendering techniques. In case of Non-realistic 3D Character Animation, first and foremost it needs investigation of the basic producing method for the 2D Animation is different with the realistic expression way of the one for the 3D animation. For a case study, expression methods for the non-realistic and the non-actuality 2D Character Animation come with impossible ways in the real life. This study for the 3D Animation with the style of 2D Animation is to investigate on the keynote for effective expression methods, when we turn 3D Animation into the style of 2D Animation.
