This paper manufactured animation to use expression for efficient action control of character animation. Animation to use expression is method to express natural animation little more easily and usefully in expression of motion. Find urea that could control animation in expression analyzing action control points of character and used in ceremony. Embodied animation to control automatically action of character on the basis of this. Efficiency of expression that animation by expression can create natural and realistic action by manufacturing that is simple was expose by advantage, but showed awkwardness than animation by key frame way by animator.

In this paper, we present an animation sketching system using a two layered approach. Animation sketching is a popular technique to create informal animations but it is often suffered by the low-quality output due to a trade-off between convenience and complexity. Our aim is to support sketching practical animation scenes easily and fast while not complicating the simple sketching interface. The key idea is to combine two conceptual stop motion layers, a whiteboard and cutout animation layer, in a seamless interface. As a background, the whiteboard animation layer handles stroke-oriented objects, while the cutout animation layer takes charge of transform-oriented objects. We found that this approach enables users to express more complicated animation fast while still maintaining a concise sketching interface. We demonstrate the usability and flexibility through resulting animations from user experiments.

In this paper, we propose an efficient algorithm to compress simple computer cell animation at very low bit rate. The structure of proposed algorithm consists of intra frame coding and inter frame coding. In inter frame coding, animation is encoded by color quantization using a palette, rearrangement of index, ADPCM used in JPEG-LS, mapping, classification, and entropy coding. In interframe coding, classifying the characteristics of motion, animation is encoded by block based motion replenishment. Experimental results show that the proposed methods turns out to outperform conventional methods including Flash, FLC, Motion-JPEG, MPEG-1, and MPEG-4.

Anime is very popular in Japan, it has also gained a following in America and is beginning to hit the mainstream. Anime is gaining popularity in the United States as it is shown more on television, most noticeably on the Sci-Fi Channel with shows such as Saturday Anime and during Anime Week and on Cartoon Network with shows such as Sailor Moon and Dragon Ball Z being shown every weekday during the Toonami block. In this paper, I present the key factors behind the success of anime in USA. To find out the factors, I research literature and simple survey. The differences of anime from us animation make anime popular. Anime-related goods such as video games, trading cards, and characters' jewelry aid the anime growing popularity. A booming trend in admiration for Japan is one of the key factors behind anime's success. In spite of disputing about Japanese animation, anime is starting to have some influence on US animation and also young American. Anime's success factors in USA could suggest that Korean Manhwa and Korean animation have to prepare strategies for rising popularity in oversea.

A hierarchical motion control system for animation of 3D human character is implemented using the motion database in realtime. The proposed motion control system consists of coordination controller for gait timing and balancing of walking motion, joint servo controller for realistic limb movement, and motion database for goal-directed character animation which makes time-consuming animation relatively easy task. As one example among the various applications of the proposed motion control system. We present a simple virtual reality system in which the motion control system plays a central role in generating realistic motion of virtual human character.

Various adaptive mesh refinement techniques are often employed in numerical simulations for increasing spatial and temporal resolution beyond the limits imposed by available CPU time and memory space. Recently, an octree-based adaptive mesh structure was successfully used in fluid animation to place more grid cells efficiently in visually interesting regions of fluids. In an attempt to optimize the use of computational resources further in fluid animation, this paper extends this adaptive technique by modifying the mesh refinement scheme so that the camera's viewing properties are dynamically exploited during the simulation. Based on a simple adaptive mesh structure, we show that the new meshing strategy can save a substantial amount of computation time and memory space by using a view-dependent adaptive approach. The experimental results reveal that the proposed technique provides a good compromise between the computational effort and the simulation's fidelity, and may be used quite effectively in 3D animation production.

They use emoticons as assistance to express their emotion on CMC communications. Emoticons have been developed into diverse forms like text emoticon, image emoticon, animation emoticon. However emoticons represent the emotion only in simple way, not in specific because the shortage of grouping expressions of the emotion. So, the emoticons used nowadays should be grouped specifically in order to help produce the modulated animation emoticons those are able to represent the feeling in specific and diverse way and be used conveniently. Therefore, this thesis is going to propose the design method of a new kind of animation emoticons those can make what animation emoticons used nowadays are not able to through the grouping and analyzing expression images according to faces, gesture(hand), and backgrounds(decoration) focused on the animation emoticons in messenger programs.

The Disney Studios have been aiming at the animation storytelling of the signification system that the contemporary audience can universally accept. And it can be said that such storytelling is aesthetic expression based on the contemporary mainstream dominant mythology. Seen from this perspective, the changes of the masculinity of male characters that are represented in the Disney feature animation Frozen are not just a simple aesthetic phenomenon but a strategy of animation storytelling that reflects the contemporary cultural and social trend. The gender identity of the male characters of Frozen is completely freed from the existing stereotypes about Disney feature animations, and it positively presents the changes of the gender roles that reflect the changes in social value and the needs of the times.
