This study shows that clothes to be just the same as the real thing can be Produced through the third dimension computer graphics, and then presents that not only the area of fashion design can be expanded in the virtual reality field by doing the simulation of the fashion show, but also the information can be made the real time public ownership and the communication can be fulfilled smoothly. In this study, analyzing the third dimension computer graphic programs to be used much at present, Alias Wavefront Company's Maya software which was the most effective in the clothes simulation and the clothes CAD SGS OptiTex 8.7 which went well substitutive for it were used of them. The conclusions of this study that got through the work manufacture are as follows： The first, if the file manufacturing in the clothes CAD by using the computer was stored, the pattern used 3D simulation was available because it could be summoned in 3D software. The second, if the data of DXF form in Maya program was summoned, they could not be applied by Maya Cloth supported in Nurbs only because they were recognized as the DXF＿layer. So the curve along the outer lines of the pattern was drawn and Maya Cloth was applied to be possible to get the natural silhouette of clothes. The third, when the clothes were manufactured by 3D, if the draping character was applied according to the textile special quality, not only the control of textile's thickness, weight, quality feeling, and silhouette was available, but also the clothes were available to graft the special textile materials. The fourth, the natural motion of model was produced by capturing the actual model's walking action In order to produce the fashion show motion and also the dynamic fashion show was available by the angle of camera, the establishment of lighting, and etc. in the final rendering. The clothes manufactured by 3D are available to change the design by changing the materials, or by adding the details, or by utilizing the special materials on clothes. Therefore, the trial and error following at the clothes manufacture can be reduced. But the elevation of the rendering speed, the price down, the strengthening of personal security, and etc. are required.

This paper presents a mews event reenactment system (NERS), which generates virtual character animations in a quick and convenient manner. Thus, NERS can be used to produce computer graphics(CG) scenes of news events that are hard to photograph, such as fire, traffic accident, cases of murder, and so on. By using plenty of captured motion data and CG model data this system produces an appropriate animation of virtual characters straightforwardly without any motion capturing device and actors in the authoring stage. NERS is designed to be capable of making virtual characters move along user-defined paths, stitching motions smoothly and modifyingthe positions and of the articulations of a virtual character in a specific frame. Therefore a virtual character can be controlled precisely so as to interact with the virtual environments and other characters. NERS provides both an interactive and script-based (MEL: Maya Embedded Language) interface so that user can this system in a convenient way. This system has been implemented as a plug-in of commercial CG tool, Maya (Alias/wavefront), in order to make use of its advanced functions

Non-photorealistic Rendering(NPR) is a method that can be used to simulate a wide range of materials used in visual arts. Currently, there is lack of availability for oriental-style rendering in 3D animation in contrast to the commonly available western-style rendering. In this paper, we combine the wash drawing technique and NPR to create an oriental-style shader for 3D animation. Our approach makes use of the Maya Embeded Language(MEL) to implement this new technique.

본 논문은 마야(Maya) 3D 콘텐츠를 제작하는데 있어서 물, 불, 안개, 폭파 장면과 같은 특수한 효과를 표현하는 방법에 대하여 연구하였다. 마야를 이용하여 3D 콘텐츠를 제작시 특수 효과는 주로 마야의 다이나믹스를 활용한다. 본 연구에서는 마야로 구현된 객체에 에프터이펙트를 사용하여 특수효과를 표현 방법을 연구하였다. 마야 다이나믹스에 비해 에프터 이펙트는 실시간 렌더링이 가능하고, 텍스쳐 에니메이션이 마야의 다이나믹스 보다 사용하기 편리하며, 다양한 표현이 가능하다. 본 논문에서는 마야 다이나 믹스의 장단점과 에프터 이펙트의 장단점을 설명하고 각각의 효과를 적용한 결과를 제시한다.

With the recent increase in YouTube content, many YouTubers are shooting with a handheld camera. Audiences are increasingly accustomed to the movement of handheld cameras. As the camera moves faster than the camera movement of the old movies, and the camera moves splendidly to the music of the music video, the camera movement in CG animation is also needed to change. The handheld Steadicam creates a natural camera movement by compensating so that the screen does not vibrate significantly even when the vibration is large and by minimizing rotation. In order to implement such camera movement, we tried to make a handheld Steadicam using nParticle simulation of Maya software and apply it to the scene to verify whether it is possible to implement the necessary natural and various movement.

Recently, the use of Unreal Engine for animation production is increasing. In this situation, Unreal Engine's 'MetaHuman Creator' helps make it easier to apply realistic characters to animation. In this regard, we tried to produce animations using 'MetaHuman' and verify the effectiveness and differences from the animation production process using only Maya software. To increase the efficiency of the production process, the animation process was made with Maya software. We tried to import animation data from Unreal Engine and go through the process of making animations, and try to find out if there are any problems. And we tried to compare animations made with realistic 'MetaHuman' characters and animation works using cartoon-type characters. The use of the same camera lens in realistic character animations and cartoon character animations produced based on the same scenario was judged to be the cause of the lack of realistic animation screen composition. The analysis revealed that a different approach from the existing animation camera lens selection is required for the selection of the camera lens in the production of realistic animation.

일반적으로 온전한 형태의 구조물을 파괴하고 물리적인 움직임을 주기 위해서는 리지드 바디 시뮬레이션(Rigid Body Simulation)을 이용한다. 그러나 다량의 복잡한 파편을 시뮬레이션하기에는 리지드 바디 시뮬레이션은 과도한 계산량과 소요시간으로 인해서 그 효용성이 상당히 떨어진다. 이에 리지드 바디 시뮬레이션보다 상대적으로 계산량과 소요시간을 줄여주고, 효과적으로 다량의 복잡한 파편의 움직임을 사실적으로 시뮬레이션하기 위한 방법을 제시하며 Maya의 C++ API 및 MEL을 사용하여 구현하였다.

This paper considers the moisture permeability and fashion in the upper fabrics of cotton fabric shoes woven into various tissues and properties measured to examine the use as upper fabrics. We measured the tissues of the manufactured upper fabric are 1/3 twill, $4{\times}4$ weft rib, Maya, Triple, Deformed twill design (DTD), Diamond tissues and tear strength, tensile strength, breaking elongation, stretching under load at 100N, stitch tear resistance, and fastness. In the case of $4{\times}4$ weft rib, the tear strength and tensile strength were excellent; however, the elongation and stitch tear resistance at 100N load were less than the standard value. DTD fabrics are characterized by physical properties in the warp direction that are superior to those in the weft direction; however, the tear strength and tensile strength in the weft direction are less than the standard value. The 1/3 twill fabrics showed high tensile strength value and stitch tear resistance value in the warp direction; however, toughness, the main property of the shoe upper, was below the standard value. Triple and diamond fabrics, which have a significant effect on the performance of the shoe upper fabric, also had less than the standard value of tear strength. Maya upper fabric for shoes has better properties than other upper fabrics except for the elongation at break, and the stitch tear resistance has a value of 178% in the warp direction and 214% in the weft direction compared to the standard value. Therefore, the Maya fabric showed the possibility of being used as an upper textile for shoes.

In this paper, we introduce a simulation tool for solar system using 3D animation tool MAYA. It accurately models solar system's astronomical features, such as each planet's orbital period, orbital speed, relative size, and texture, etc. This simulator visualize the solar system in 3D, which can be used to easily understands the system's positioning and astronomical movements. With a conventional Maya modeling process using menus and UI windows, it is difficult to assign correct physical attributes of planets. We use Python script to set up each planet's astronomical parameters. The proposed simulator is rendered as real as possible to be used for virtual reality and educational purpose.
