This paper presents animation techniques and issues involved in virtual environments where the participants interact with each other through a network. The state of the participant should be recognized at each local site, and broadcast to the other sites. Because information exchange is minimal, animation techniques are applied to convert the incoming low DOF parameters into high DOF joint angles that completely determine the configuration of the agents at each frame. As a case study, a software system VRLOCO is introduced, which has been developed by the author over the last five years. From a simple stream of body center positions, VRLOCO generates realistic curved path human locomotion in real-time. Based on the heading direction and speed, the locomotion automatically switches among five different primitives: walking, running, lateral stepping, backward stepping, and turnaround. The techniques presented here proved robust and faithful: the algorithm is not sensitive to the noise in the data, and the resulting animation conforms well with the original data.

In this paper, we propose a 3-D animation system to track and analyze motion of the human object. The proposed system consists of two separate layers: motion analysis layer and 3-D model registration layer. Following the MPEG-4 SNHC standard, we generate object motion using body definition and animation parameters. In the implemented system, we acquire human motion data from a single camera and extract body definition parameters from arbitrary VRML human models.

This paper proposes a GPU-based approach to real-time skinning animation of large crowds, where each character is animated independently of the others. In the first pass of the proposed approach, skinning is done by a pixel shader and the transformed vertex data are written into the render target texture. With the transformed vertices, the second pass renders the large crowds. The proposed approach is attractive for real-time applications such as video games.

In this paper, we designed 2D, 2.5D cloth design system and a 3D cloth animation system. They make the 3D cloth animation possible by using coordinate points extracted from 2D and 2.5D cloth design system in order to realize a system that allows customers to wear clothes in the virtual space. To make natural draping, it uses for description the mesh creation and transformation algorithms, path extraction algorithm, warp algorithm, and brightness extraction and application algorithms. The coordinate points extracted here are received as text format data and inputted as clothing information in the cloth file. Moreover, the cloth file has a 2D pattern and is realized to be used in the 3D cloth animation system. The 3D cloth animation system generated in this way builds a web-based fashion mall using ISB (Internet Space Builder) and lets customers view the clothing animation on the web by adding the animation process to the simulation result.

The term 'animation' derived from the Latin 'anima' meaning spirit, life, or vitality. Although its original meaning was somewhat related to creation of life or incorporation of vitality into an inanimate or nonexisting entity by providing mobility through artificial manipulation, it is now used in a rather narrow sense to define collectively the cartoon-based films or tape-recordings and specialists who are involved in animation production or related areas are called animators. The current worldwide market for animation production is progressing and expanding enormously. Although the domestic animation market is ranked as third in the world in terms of overall quantity, the reality is that there are few high quality products that can compete with foreign animation products in the global markets. This issue is further discussed in this paper along with the current status of the domestic animation technology and production. This investigation concerns the comparative analysis of literature data on foreign and domestic animation, which can be a basis for the production of internationally competitive animation work.

The paper presents a multimedia educational program of DC servo drives for distant learning with a special emphasis on sliding mode control. The program contains of three parts: animation, simulation and internet based measurement. The animation program explains the operation of DC motors, gives its time- and frequency-domain equations, transfer functions and the theoretical background necessary for controller design for DC servo motors. The simulation model of the DC servo motor and the controller can be designed by the students based on the animation program. The students can also test their controllers through the internet based measurement, which is the most important part from engineering point of view. After the measurements are executed, the students can download the measured data and compare them to the simulation results.

Since the birth of animation, the United States has created many classic characters. For example, Mickey Mouse and Minnie, Tom and Jerry, Lion King, and Nemo, which are imaged with animal images, include Snow White, Bell, Mulan, and Aladdin. In addition, there are villain characters designed with strong personality and personality design, such as Snow White's stepmother Grimheel, Ursula, Bad Girl Crew El Radville, Scar, Captain Hook, and so on. These animation characters have been remembered for a long time with stories in people's minds, and have also brought laughter and emotion to people all over the world, which has brought a lot of business value to animation companies. Recently, the villain of American animation works is becoming more and more suited to the taste of the audience. The villain is not a symbolic image of the brutality we have seen before. They are not only visual images with rich and diverse personalities, but are also designed to suit the tastes of the public with a multifaceted inconsistency. They appear as ordinary people in our lives in works, or as powerful people who are not realistic. The villain characters designed in this way are real human miniatures appearing in the relationships in our lives, and they cannot judge good or bad only by their appearance. Through the study of villains in American animation, many villains in American animation were summed up, and villains could be classified into three types: brutal, violent, and sneaky. Based on this, it was possible to analyze the appearance and attire of the villain character in American animation, and to create a vivid and popular image of the villain, it was found that the character of the character should be emphasized when constructing the shape and costume of the villain character. In conclusion, the attractive formation of villain characters is an important part for successful animation. The production of vivid and long-lasting villain characters must begin with detailed settings such as personality, shape, and dress from the planning stage, which is not only the intention of the producer, but also a reflection of the aesthetic psychology that society should pay attention to today.

The needs for visualizing interactive multimedia contents on portable devices with realistic three dimensional shapes are increasing as new ubiquitous services are coming into reality. Especially in digital fashion applications with virtual reality technologies for clothes of various forms on different avatars, it is required to provide very high quality visual models over mobile networks. Due to limited network bandwidths and memory spaces of portable devices, it is very difficult to transmit visual data effectively and render realistic appearance of three dimensional images. In this thesis, we propose a compression method to reduce three dimensional data for digital fashion applications. The three dimensional model includes animation of avatar which require very large amounts of data over time. Our proposed method utilizes temporal and spatial coherence of animation data, to reduce the amount. By grouping vertices from three dimensional models, the entire animation is represented by a movement path of a few representative vertices. The existing three dimensional model compression approaches can get benefits from the proposed method by reducing the compression sources through grouping. We expect that the proposed method to be applied not only to three dimensional garment animations but also to generic deformable objects.
