In the field of computer graphics, rendering speed is one of the most important factors. Contemporary rendering is performed using 3D graphics systems with windowing system support. Since typical graphics systems, including OpenGL and the DirectX library, focus on the variety of graphics rendering features, the rendering process itself consists of many complicated operations. In contrast, early computer systems used direct manipulation of computer graphics hardware, and achieved simple and efficient graphics handling operations. We suggest an alternative method of accelerated 2D and 3D graphics output, based on directly accessing modern GPU hardware using the direct rendering manager (DRM) system. On the basis of this DRM support, we exchange the graphics instructions and graphics data directly, and achieve better performance than full 3D graphics systems. We present a prototype system for providing a set of simple 2D and 3D graphics primitives. Experimental results and their screen shots are included.

오늘날 많은 IT 관련 분야에서 컴퓨터 그래픽스 기술이 사용되고 있다. 더욱이 3D 프린터, Head Mount Display, VR & AR 등 컴퓨터 그래픽스와 밀접하게 관련된 분야에 대한 수요가 급증하고 있다. 앞으로 컴퓨터 그래픽스 분야는 더욱 전문화되고 이에 따른 인력의 수요도 증가할 것이다. 그러나 그래픽스 분야가 수학적 배경지식을 많이 요구하기 때문에 접근성이 낮고, 수요에 비해 이를 전공한 사람과 전문가의 숫자가 적다. 만약 그래픽스 프로그래밍을 쉽게 배울 수 있는 환경을 제공하다면, 컴퓨터 그래픽스 분야 인력 양성에 도움이 될 것이다. 따라서 이 논문에서 그래픽스 이론을 분석하여 초심자도 체계적이고 쉽게 배울 수 있는 교육용 소프트웨어 모델을 제시한다. 웹과 블록을 이용한 설계를 통해 접근성과 직관성을 높이고, 이론적인 내용을 중점적으로 학습할 수 있는 환경을 구축하는 방법을 제안한다.

최근 컴퓨터그래픽스는 실사에 가까운 표현이 가능하게 되었다. 하지만, 2D 컴퓨터그래픽스 고유의 느낌을 선호하는 면도 없진 않다. 2D 컴퓨터그래픽스와 3D 컴퓨터그래픽스의 합성 작업은 이미 오래전부터 제작되어왔다. 하지만, 기술적인 차이로 한계를 넘지 못하거나 실사 2D에 가상의 3D 컴퓨터그래픽스가 도입되거나 2D 컴퓨터그래픽스에 이펙트 등 효과가 3D 컴퓨터그래픽스 작업을 통해 제작되어 왔다. 최근에는 웹툰 등 2D 컴퓨터그래픽스로 작업하면서 시간적으로 좀 더 제약을 많는 콘텐츠 등에 2D 컴퓨터그래픽스로 작업한 느낌을 살리면서 카메라 앵글이나 시공간적인 장면 전환이 용이한 요소를 3D컴퓨터그래픽스로 작업하여 작업의 효율을 높이는 경우가 있다. 실제 작업을 통해 적절한 방향을 제시해보고자 한다.

본 논문에서는 전용하드웨어를 사용하지 않는 새로운 구조의 범용 그래픽 쉐이더 프로세서를 제안한다. 최근 모바일 기기에서는 고성능을 유지하면서 저전력의 작은 크기를 가지는 그래픽 프로세서를 요구한다. 제안하는 쉐이더 프로세서는 OpenGL ES 2.0 그래픽 파이프라인 전체를 쉐이더 명령어로 실행할 수 있는 GP-GPU 구조를 갖는다. 프로그램을 구현하여 하나의 프로세서로 모든 그래픽 파이프라인 처리가 가능하기 때문에 Rasterization Unit과 같은 별도의 전용 하드웨어를 필요로 하지 않는다. 따라서 쉐이더 프로세서 하나로 Fully Programmable 3D Graphics Engine 구현이 가능하며 기존 쉐이더 프로세서에 비해 하드웨어 크기를 60% 줄였다.

The purpose of this thesis is to suggest objective basic data for the super graphics in the urban landscape through the quantitative visual quality analysis. For this, the image structure of super graphics have been measured mainly by questionnaries and semantic differential scle method and analyzed by the method of factor analysis, means and multiple regression. Degree of visual preference have been measured mainly by questionnaries and likert attitude scale method and finaly these data have been analyzed by using the stepwise method. The data were collected by presenting 12 super graphics photographs-4 each sample pictures from the 3 each selected districts representing typical urban landscape style(central business district, shopping district, apartment complex). Observer groups were categorized as professionals, students, the others. Result of this thesis can be summarized as fallows: 1. From all 12(3${\times}$4) sample super graphics, the value of each semantic differential scale among the observer groups were presented significant group difference. But no significant difference of the S.D. scale value were observed among central business district, shopping district and apartment complex super graphics. 2. For all experimental points, 4 types of factor have been observed. Factors covering the image of super graphics were found to be the evaluation, the intimacy, the potentiality and the tidiness. 3. Main factors of the super graphics image and factors indicating the group variations yielded high significance between areas. 4. The harmony with surrounding environment, the proper selection of super graphics subject yielded high values for all groups. Especially, the good color sense with building was the most important variable determining the degree of visual preference. 5. The urban C.B.D. super graphics obtained 5∼12 ranks of regional visual preference and the shopping district super graphics obtained 2∼11 ranks, and apartment complex super graphics obtained 1∼7 ranks.

^x The enviroment defines the living conditions for people and has at the same time the possibility to create new environment. In Korea, where the rate of urbanization reached more than 50% in 1970′s the priority has been put on the economic development and administrative function. Under the circumstance, visual environmental field was dealt lightly and it resulted in undesirable environment. The techniques of Mordern Arts (Montage, Depeysment, Tromp L′oeil, P.O.P Art, etc.) helped Super Graphics appear in the urban areas. Environmental Art has been expended into the public space and people came to recognize the Arts as the "Street Art" or "Street as Gallery". Super Graphics has four types 1) Resident′s Super Graphics ; Minority groups came to maintain social equality and rights, in cooperation with each other. Such maintenance required general urbanites to form communities which gave birth to the community art, Mural Painting. 2) Environmental Super Graphics ; Beauty has come to be stressed in order to improve the quality of urban lives in the course of inescapable urban development. Instead of renewal of all established construction conservation oriented renewal was encouraged. 3) Super Graphics as Population Arts ; In the 1960′s artists repulsed the establishments in an efforts to open new phase independent from the expressional in the arts. They recognized the relationship between painting, society and the public in different angle and tried to describe all living space on canvas. 4) Super Graphics as Advertisement ; Super Graphics functions as efficient media to deliver images to the urbanites. Super Graphics as media plays the role for political propaganda and commercial advertisements according to their purposes. In Korea, especially, it is required to introduce the environmental Super Graphics. But it is desirable to introduce Super Graphics with Korean culture and sense of beauty. Designers themselves are also required to have responsibility to improve the quality of urban culture.

The purpose of this qualitative case study is to understand how the idea of data view and information graphics is used in the social studios middle school textbooks. Data were collected through national curriculum documents and social studies middle textbooks for 7-9 grades. We set up three questions for this studies; 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, illustrations, information maps, etc., are used and frequencies of their usages are in descending order, 2) double lines graphs, circle graphs, and stripe graphs nip often adopted for the comparison of populations, 3) the relation of the two subjects curricula is not so good, especially in the curriculum steps of information mads 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 are needed for social studies teachers.

This study was conducted to investigate the interaction effects of various presentation types of graphics and the individual differences in need for cognition on comprehension, interestingness, and motivation. The depiction of the operation of a bicycle tire pump was presented in one of the following conditions, (a) simultaneous presentation, (b) successive presentation, (c) self-pace presentation, (d) animation. For younger students, animated graphics are rated more enjoyable and motivating only when they are low in NFC. If they are high in NFC, animated graphics are not more effective than static graphics in terms of comprehension, interest, and motivation. On the other hand, for older students, self-paced static graphics are more interesting and enjoyable than the animated graphics regardless of their NFC score. These results suggest that the animated graphics are not always beneficial for loaming and motivation.
