By logging position data from GPS-equipped construction machines, we re-create daily activities as 3D animations to analyze performance and facilitate look-ahead scheduling. The 3D animation enables going back to any point in time and space to observe the activities as they took place. By segmenting data into a set of activities, it is possible to obtain actual measures of performance such as cycle times, production, speed profiles and idle times. The measures of performance can then be compared to those expected (e.g., theoretical speed profiles vs. observed profiles), and instances of significant difference can be flagged for further investigation. Idle times and queues that exceed prescribed thresholds can also be identified. In general, many of the traditional real-time performance analyses can be performed after the fact. Situations of interest can be identified automatically and the events in this manner enhances effective performance improvement in construction. The proposed research is explained and demonstrated using a real push-loaded earthmoving operation.

This research was analyzed regarding comparing features of expressions between clothes in movie, , and cyber clothes that were made by Marvelous Designer2 which is a design CAD. This research was studied to experiment an expressing possibility of clothes simulation software which was developed currently. Therefore, we picked clothes that are good at movement and detail in the movie. The dress theory of the renaissance which is the period background of movie, was considered and studied as pattern, silhouette, material, color, detail and animation. The movie's dresses are made with 3D virtual and compared so 3D virtual clothes's benefits and weaknesses can be analyzed. As a result, we found that 3D virtual dress can show the real movie's feature accordingly with current developed IT standard. This will assist a development in fashion industry and become a new indicator for 3D movie clothing.

Due to increased interest in character costumes, the field of animation character costume design is gradually developing into a specialized domain. The costume-making process for animation characters presents many differences from the costume-making process for regular apparel. However, there remains insufficient research on the actual process of making the character costumes used in stop motion videos both in Korea and abroad. The purpose of this study is to establish a costume design process for animation characters. Furthermore, this study presents a case study on the costume planning and making process for 3D stop motion animation characters. The character costume-making process was segmentalized into the following stages: character analysis stage, character modeling stage, and character costume making stage. In the character analysis stage, the investigator analyzed the character's movements, designed the character images, and analyzed the movements and motions of the animation characters. After completing character modeling, this study proposed a method for making the character costume. The style of the character costume was designed, and the structural design reflected the position and size of joints as well as the angle of movements. The patterns of the character costume were produced through dimensional tailoring after measuring the body size of the character. Afterward, the costume was completed after passing through the fitting and revision stages. The clothing material was selected to fit the colors and feelings shown in the illustration. To complete the costume after comparing it with the initial illustration, it was revised based on the assessment of its volume and overall atmosphere.

This article intends to draw the Road map of Korean International Animation Festival through the research of background and its identity of 4 International Animation Film Festivals Such as Annecy, Zagreb, Ottawa and Hiroshima. I was given opportunity to visit Annecy since 2009, it brought me to the real attraction of animation for watching of pleasure and passion of the people those who love animations. For the combining more advanced system and structure for Animation Festival in Korea, I had to do research all the information from the documents from the Annecy Collections. though I have not get the chance to go others except Annecy, However, I could get their background and history whenever I met the other Festival Committee Members. These Festivals showed us successful Road Map for the Animation Festivals in Korea as a role model. For the getting advanced system of Animation Festivals in Korea. It requires the animation theater for animation, effort for the Audiences's Convenience and international network composition system. However, the last task of us is to make people to entertain and enjoy the animation Films, its world of attraction.

In computer graphics and computer vision research and its applications, various representations of 3D objects, such as point clouds, voxels, or triangular meshes, are used depending on the purpose. The need for animating characters using these representations is also growing. In a typical animation pipeline called skeletal animation, "skinning weight painting" is required to determine how joints influence a vertex on the character's skin. In this paper, we introduce a neural network for automatically performing skinning weight painting for characters represented in various formats. We utilize signed distance fields (SDF) to handle different representations and employ graph neural networks and multi-layer perceptrons to predict the skinning weights for a given point.

This paper presents a traveler guidance system that offers 3D street information such as road types, signal light systems, street trees, buildings, etc. We consider 5x4 road system of Gangnam(in Seoul, Korea) as a test area and reflect the traveler's car-driving situation. A web server is constructed to serve traveler's driving path by switching 3D animation scenes automatically. To do batch processing of geometric data for the 3D graphical streets construction, we have extracted major street information from present GIS database and created new GIS file formats (SMF files), which contain data sessions for links, nodes, and facilities. With these files, we can render 3D navigation scenes. A number of vector calculations were performed for the geometrical consistence and texture-mapping method was used for the realistic scene generation. Finally, we have verified the effectiveness of the service by operating a test scenario. We have checked whether traveler's 2D path and 3D navigation are exactly reported after setting specific departure and destination. This system offers us well awareness of streets and takes useful role of traveler guidance.

We suggest the dynamic stroke generation algorithm that provides frame-to-frame coherence in 3D non-photorealistic animations. We use 3D particle system to eliminate the visual popping effect in the animated scene. Since we have located particles on the 3D object's surface, the coherence is maintained when the object or the camera is moving in the scene. Also, this algorithm maintains the coherence when camera is zooming in/out. However, the brush strokes on the surface also zoom in/out. This result(too large or too small brush strokes) can not represent hand-crafted brush strokes. To remove this problem, we suggest stroke generation algorithm that dynamically maintains the number of brush stroke and its size during camera zoom in/out.

The Augmented Reality, as a technology caught the spotlight as a next generation's technology of inserting 3D virtual objects in the space of reality seen through the camera, can maximize the learning effects by inducing user's absorption and interest using interaction between user and objects. Recently, as the movile devices having excellent mobility and portability are generalized, the diversified augmented reality are introduced using mobile devices. In this article, a 3D fish encyclopedia system augmented from the mobile environment was designed to provide the user with learning contents focusing on the sense of absorption and an interest. This system is intened to provide helps to learn about the fishes by recognizing the pictures of fishes in the encyclopedia as marker, bringing out the 3D model stored in server and displaying in the mobile environment.

컴퓨터 하드웨어 기술과 멀티미디어 기술의 발달로 멀티미디어 입출력 장치를 이용한 고급 인터메이스의 필요성이 대두되었다. 친근감 있는 사용자 인터페이스를 제공하기 위해 실감 있는 얼굴 애니메이션에 대한 요구가 증대되고 있다. 본 논문에서는 사람의 내적 상태를 잘 표현하는 얼굴의 표정을 3차원 모델을 이용하여 애니메이션을 수행한다. 애니메이션에 실재감을 더하기 위해 실제 얼굴 영상을 사용하여 3차원의 얼굴 모델을 변형하고, 여러 방향에서 얻은 얼굴 영상을 이용하여 텍스터 매핑을 한다. 변형된 3차원 모델을 이용하여 얼굴 표정을 애니메이션 하기 위해서 해부학에 기반한 Waters의 근육 모델을 수정하여 사용한다. 그리고, Ekman이 제안한 대표적인 6가지 표정들을 합성한다.
