In this paper, studied about an effect in motion graphics to make video game contents projects. Using the motion graphics to make video game contents projects was applied with various effects. The effects in motion graphics is divided in two ways that moving effects and a motion image effects. The various effects of motion graphics extremely increases the effects of the video game contents projects. The various effects in the motion graphics, expects to be applied in the video game that can be more developed creative in video arts.

DirectX Graphics plays the role of hardware independent 3 dimensional drawing interface for 3 dimensional video display. However the APIs in DirectX Graphics provide not only small improvement in velocity in the lowest level but also unstable performance of velocity according to their usages. In this paper, we present the structure of 3D game engine of efficient performance and describe functions and implementational features of game engines for an efficient 3D rendering in the environment of DirecX Graphics.

In this paper, two-stage pipelined floating-point arithmetic unit (FP-AU) is designed. The FP-AU processor supports seventeen operations to apply 3D graphics processor and has area-efficient and low-latency architecture that makes use of modified dual-path computation scheme, new normalization circuit, and modified compound adder based on flagged prefix adder. The FP-AU has about 4-ns delay time at logic synthesis condition using $0.18{\mu}m$ CMOS standard cell library and consists of about 5,930 gates. Because it has 250 MFLOPS execution rate and supports saturated arithmetic including a number of graphics-oriented operations, it is applicable to mobile 3D graphics accelerator efficiently.

본 논문은 3D 스캐너 및 센서 등으로 캡처되어 3D로 복원된 얼굴 객체의 부위별 의미 있는 영역에 대한 분할을 자동으로 수행하는 기술을 제안한다. 3D 스캔된 얼굴 모델을 모델링, 애니메이션, 3D 프린팅 등의 다양한 응용분야에 활용하기 위해서는 스캔된 영역의 의미 있는 부위별 인식이 필수적이다. 본 논문에서는 부위별 의미 있는 영역 레이블링이 된 템플릿 모델을 입력된 3D 복원 모델로 전이하여 복원된 3D 모델의 부위별 의미 있는 영역을 자동으로 분할하고 분할된 영역의 일관성을 유지하는 알고리즘을 제안한다.

The number of pixels being processed in a raster graphics system often exceeds 1 million per frame. Replacing fractional arithmetic by integer arithmetic on rendering graphics primitives will therefore significantly improve the rendering performance. A scaling method that replaces fractional arithmetic by integer arithmetic on rendering graphics primitives is introduced. This method is applied to the filtered edge drawing and Gouraud shading. This method will also be applicable to some of other incremental algorithms for rendering graphics primitives. Because the scaling method requires only simple modifications upon the known algorithms that already have been implemented in ASIC (Application Specific Integrated Circuit), our algorithms can easily be implemented in ASIC. Our method will be useful especially for the low-price systems (e.g., home game machines, personal computers, etc.).

The purpose of this qualitative case study is to understand how the idea of data view and information graphics is used in the social studies high school textbooks. Data were collected through national curriculum documents and social studies middle school textbooks for the 10th grade students. We set up three questions for this study; what kinds of information graphics are used in the textbooks, how the graphics are organized in the social studies middle school, and how the 7th social studies curriculum is related with the 7th national mathematics curriculum. Through the data analysis, we found that 1) photographs, information tables, illustrations, etc., are used and frequencies of their usages are in descending order, 2) double lines graphs, and stripe graphs are often adopted for the comparison of populations, 3) the relation of the two subjects curricula is not well developed, especially in the curriculum steps of information maps, scatter diagrams, and comparison of populations. Finally we suggest that new web site of data view or information graphics be provided for two curricula, workshop of information graphics be needed for social studies teachers, and modification of the 7th probability and statistics curriculum.

So far, the graphics of Korean clothing have focused on maintenance of forms without specific improvement. In particular, in the archetypal design of a Jeogori, ambiguous standards on the overlapping of left and right collars and collar strips cause problems in the teaching and teaming of Korean traditional clothing. As a result, the graphics of men's Durumagis based on a Korean Jeogori have the same problems as Jeogoris and the connection between them has not been sufficiently studied. Design of "Moo" in respect to graphics of men's Durumagis has its own calculation equation or measures, but they can not be generalized. This study therefore considers the existing graphics of men's Durumagis or approaches of Moo in different angles by reviewing the connection between Durumagis and Jeogoris. Therefore, archetypal forms of Durumagis are designed with a radius of a circle using one's height and the girth of one's chest, which contributes to symmetry of the collars and teaming effects through scientific graphics of "Moo." It is further expected that can be mass-produced through archetypal design of overcoats and graphics of "Moo" of Durumagis that can be standardized as well as connection between graphics of Jeogoris and Jeogoris.

본 논문은 파티클을 이용하여 다상의 기체에 대한 형상 제어를 수행하는 기법을 제안한다. 유체를 하나의 목표 형상으로 변형시키기 위한 힘만 샐에 적용하는 기존 연구와 달리, 본 논문에서는 단일 밀도장내에서 파티클마다 다른 목표 형상으로 가고자 하는 힘을 정의하여 서로 다른 성질의 유체를 구성하는 파티클이 각자의 목표 형상으로 진행하는 동시에 상호작용이 가능하도록 하였다. 또한, 목표 형상 내부에서의 분산력을 정의하여 파티클들이 목표 형상에 도달한 후에도 목표 형상의 세밀한 특징을 표현하기 위해 멈추지 않고 고르게 분산되게 하였다.

We developed a Off-Line Graphic Simulator which can simulate a robot model in 3D graphics space in Windows 95 version. 4 axes SCARA robot was adopted as an objective model. Forward kinematics, inverse kinematics and robot dynamics modeling were included in the developed program. The interface between users and the off-line program system in the Windows 95's graphic user interface environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by Silicon Graphics, Inc. were utilized for 3D graphics.
