In this paper, we developed a windows 95 version Off-Line Programming system which can simulate a Robot model in 3D Graphics space. 4axes SCARA Robot (especially FARA SM5) 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 OLP system in the Windows 95's GUI environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by silicon Graphics, Inc. were utilized for 3D Graphics.

This paper presents a design and MPW implementation of 3D Graphics Floating Point IPs. Designed IPs include adder, subtractor, multiplier, divider, and reciprocal unit. The IPs have pipelined structures. The IPs meet the accuracy required in OpenGL ES. The operation frequency of the IPs is 100MHz. The IPs can be efficiently used in 3D graphics accelerators.

We propose a unmaned integrating control system based-on Windows XP version Off-Line Programming System which can simulate a Robot model in 3D Graphics space in this paper. The robot with 4 and 6 axes modeled SM5 and AM1 respectively were adopted as an objective model. Forward kinematics, inverse kinematics and robot dynamics modeling were included in the developed off-line program. The interface between users and the off-line programming system in the Windows XP'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.

3D 그래픽 프로세서의 시스템의 특성상 많은 수학적 계산이 요구되면서 고속처리를 위하여 GPU(Graphics Processing Unit)를 이용한 병렬처리 연구가 많이 진행되고 있다. 본 논문에서는 GPU에서 발생하는 문제점 중 캐시메모리 미스에 의하여 발생하는 대역폭 증가와 3D 셰이더 처리 속도가 일정하지 않은 문제점을 해결하기 위하여 캐시메모리를 사용하지 않는 병렬처리기인 MAMS를 이용한 3D 그래픽 프로세서를 제안한다. 본 논문에서 제안된 MAMS를 이용한 3D 그래픽 프로세서는 DirectX 명령 분석을 이용해 Vertex shader, Pixel shader와 Tiling 및 Rasterizing 구조를 설계 하였고, MAMS를 위한 FPGA(Xilinx Virtex6@100MHz) 보드를 구성하여, Verilog를 사용하여 설계된 구조를 개발하였다. 개발된 FPGA(100Mhz)와 nVidia GeForce GTX 660(980Mhz)의 처리시간을 확인한 결과 GTX 660를 이용한 처리 시간은 일정하지 않음을 확인하였고, MAMS를 이용한 처리 시간은 일정함을 확인하였다.

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.

^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.

Most of multimedia processors for 2D/3D graphics acceleration use a lot of integer/floating point arithmetic units. We present a new architecture with an efficient ALU, built in a smaller chip size. It reduces instruction cycles significantly based on a foundation of multi-thread operation, variable length instruction words, dual phase operation, and phase instruction's coordination. We can decrease the number of instruction cycles up to 50%, and can achieve twice better performance.

In this paper, we implemented and evaluated the performance of a vector-based rasterization algorithm of 3D graphics using a SIMD-based many-core processor that consists of 4,096 processing elements. In addition, we compared the performance and efficiency of the rasterization algorithm using the many-core processor and commercial GPU (Graphics Processing Unit) system which consists of 7 GPUs and each of which have 512 cores. Experimental results showed that the SIMD-based many-core processor outperforms the commercial GPU system in terms of execution time (3.13x speedup), energy efficiency (17.5x better), and area efficiency (13.3x better). These results demonstrate that the SIMD-based many-core processor has potential as an embedded mobile processor.
