Lighting work on 3D animation requires much time and labor. For example, about 60 lighting artists were needed for the theater animation named Postman Pat the Movie globally distributed in 2014. These artists were needed to rapidly respond with shot feedback. However, complicated shots required much of rendering time. Therefore, it was difficult to correspond the work in the middle of test rendering. After 2005, re-lighting techniques were developed to cope with such situations. However, it was not feasible to create shadow with current re-lighting technique which doesn't make natural or realistic result. This paper has realized relighting system that could realistic quality while maintaining fast calculation by applying rasterized ambient occlusion to the relighting calculation of each of the lights. This relighting system has been used for the Hollywood animation titled "Postman Pat: The Movie" globally released in 2014. It is anticipated for this method to be more widely used for animation manufacture that other manufacturers can reduce expenses and create well completed output in the future.

The purpose of this study is to find out the problems related to the lack of research on rapidly changing digital information media and industry flow and to suggest solutions. In Korea what is needed is basic academic research on cartoon and animation field, and the development and systemization of teaching material. As a first step to achieve this goal, standardization of cartoon and animation related terminology and publication of a dictionary of terminology are underway. To reach agreements on terms, discover new terms, standardize terms and their interpretations, and publish a standardized dictionary, experts in the fields of cartoon and animation education, industry, and academia in North America, Europe, and Japan have been invited to work together. Through these efforts, a dictionary of terminology will be published, which will not only provide useful information but also solve problems related to the use of not standardized terms.

The main purpose of this study is to help develop the productional system of the three dimensional digital animation domestically. Many 30 digital animation projects are being developed and finished with foreign computer graphics technology. However, the 3D animation market in Korea is not as good as the ones in other countries. One of the most significant problems is the lack of a program of study in Korea concerning productional systems used to create 3D animation. We previously imported an advanced productional system from the U.S., which was adaptable to big projects, and consequently, expanded the international digital animation market. Now, we need to develop a new production system which is fully adaptable to the Korean market. A non-sequential system of 3D digital animation tailored for small projects is more adaptable to domestic industry than the sequential system known as the 'Pipeline system.' A non-sequential system is good for small productions that are trying to create animation on a limited budget. The workers in this system can learn to make animation fast and effectively. They can also learn how to discuss with the others in order to avoid duplication of action. In contrast, in the Pipeline System, many workers repeat confirmation steps during the process for the same animations. The benefit of the non-sequential system is that the worker's interest and education can speed up production, because he/she can quickly learn every step of the animation process instead of just doing a particular job which does not allow him/her to observe the other steps involved. The 'animatic' step is the most important in the non-sequential system. The final animation is produced from the animatic. It is developed from scratch through to the final product but only after the agreement of all the workers, including a director.

This paper presents an efficient collision detection algorithm the performance of which is independent of animation speed. Most of the previous collision detection algorithms are incremental and discrete methods, which find out the neighborhood of the extreme vertex at the previous time instance in order to get an extreme vertex at each time instance. However, if an object collides with another one with a high torque, then the angular speed becomes faster. Hence, the candidate by the incremental algorithms may be farther from the real extreme vertex at this time instance. Therefore, the worst time complexity nay be $O(n^2)$, where n is the number of faces. Moreover, the total time complexity of incremental algorithms is dependent on the time step size of animation because a smaller time step yields more frequent evaluation of Euclidean distance. In this paper, we propose a new method to overcome these drawbacks. We construct a spherical extreme vertex diagram on Gauss Sphere, which has geometric properties, and then generate the distance function of a polyhedron and a plane by using this diagram. In order to efficiently compute the exact collision time, we apply the interval Newton method to the distance function.

This paper explored the characters in spin-off works that are becoming a hot topic not only in Korea but also in the world. I would like to find out whether there are changes in the character in the original and the character's character and behavior in the spin-off work, and if there are changes, for what reason the changes occur. The subjects of the study were "Puss in Boots" and "Minions," which released a number of spin-off works based on the original. As analysis tools, we used the five-step theory of need by Abraham H. Maslow and the behavioral model of Greimas. As a result, in the spin-off work, Minions and Puss have shifted away from the role of facilitator in the original and become subjective characters. According to Maslow's theory of needs, the analysis also confirmed that this appears as an action to satisfy the needs of belonging, love, respect, and self-realization beyond basic physiological and safety needs. This change allowed him to develop a more independent and proactive personality and behavior, and be at the center of the story. This is the result of reflecting the production team's intention and audience expectations to provide audiences with deeper characters and richer stories. is analyzed.

The Cultural Revolution in the history of Chinese animation hinder the development of the initial animation, and after a negative assessment instrument provided the cause is to become sluggish growth of the Chinese animation. So this time animation are things that are the subject of academic research studies or analysis has been depreciating almost uniformly without evaluation. However, of all the cultural and artistic creation it is developing in its own specific historical conditions and has the aesthetic results. This paper puts the primary purpose is to hold in consideration the aesthetic principles that led to cultural and artistic creativity and objective perspective the achievements the Chinese animation of the time period of the Cultural Revolution. Cultural Revolution is avoided to the previous period in accordance with the socialist ideology of Mao Ze-dong(毛澤東) sikindaneun highlight the culture of the proletariat and placed our goal to create a new class culture. Therefore, cultural and artistic creation of this period is often inconsistent with this part of our aesthetic principles generally accepted character has a non- elitist and anti properties. Best drama is a creative one hand as a model to implement the principles of aesthetics, art and culture Cultural Revolution period kkophimyeo reference for understanding the aesthetic principles that animated the Chinese Cultural Revolution period of orientation. This paper has San Tu Chu(三突出), Hong Guang Liang(紅光亮), and Gao Da Quan(高大全) at the time of the Cultural Revolution aesthetic principles are reflected in how the concrete work, the Cultural Revolution when the animation is how to accommodate these aesthetic principles and placed emphasis on comparative studies on best pole and correlation of the Cultural Revolution when the Chinese animation to ensure that adaptation in own way. First, after analyzing whether the aesthetic principles of focusing on the similarities of the best pole time of the Cultural Revolution and China, and how to implement animation in the works, these aesthetic principles according to the analysis of positive and negative influence on the creation of Chinese animation It was described as neutral. The detailed analysis and comparative study courses were trying to access in two significant aspects of the characters and scenes directing. In terms of character animation of the Cultural Revolution in China when a young boy or girl, emphasis should emphasize the health tinged with red lips and cheek blush to highlight the desired Gong Nong Bing(工農兵) shape as the main character and smooth texture and sophisticated highlights the glittering feeling to the touch, it was confirmed focused hayeoteum to implement the principle of 'Hong Guang Liang', highlighting the brilliant colors with a clean, bright colors. Highlighting a number of protagoniste compared to the antagonist in the animated scene of the Cultural Revolution a few times in terms of production and, among a number of protagoniste also emphasizes the outstanding hero figure, "yet three outstanding heroes heroic figures also emphasize the leading figures among the the director of the extrusion step-by-step approach "('San Tu Chu')was used. In addition, the hero figure is generally high and low angle by directing a large and perfect aesthetic appearance was to faithfully implement the principle of 'high-charged'('Gao Da Quan').

In this paper, we propose an image-based synthesis method that can effectively represent the spark effect in fire simulation. We use the real flame image or animated image as inputs and perform the following steps : 1) extract feature vectors from the image, 2) calculate artificial buoyancy, and 3) generate and advect spark textures. We detect the edge from images and then calculate the feature vectors to calculate the buoyancy. In the next step, we compute the high-quality buoyancy vector field by integrating the two-dimensional feature vector and the fluid equation. Finally, the spark texture is advect by buoyancy field. As a result, our method is performed much faster than the previous approach and high-quality results can be obtained easily and stably.
