    In 1992, OpenGL from SGI became the most important 3D-API for engineering graphics applications including 3D CAD. The accelerating performance for OpenGL-based 3D graphics application is the first issue of current engineering workstation market. The performance of 3D CAD application is adopted in the area of the hardware devices like microprocessor, main memories, and sub memories. And software includes device drives and operating system. Although the higher performance of 3D CAD application is acquired by the optimized balance of these parts, workstation has many difficulties by generic constructing of computer system. In this paper, the improvement of the performance of OpenGL based 3D graphics for the developers and users of 3D CAD applications on engineering workstations is studied. The analysis of the performance in the configuration of microprocessor, amount of memories, OpenGL acceleration of graphic subsystem and operating environments are investigated. The effects on improving OpenGL 3D-API and 3D CAD applications by the configuration of microprocessors, memories, graphics subsystems and operating environments are also examined. The single configuration of microprocessor is better than multiple configuration. The amounts of memories are major impact element of workstation and applications. And the accelerating performance of OpenGL in graphics subsystem is not proportioned to that of 3D CAD applications. Controlling by configuring of environmental factors of graphics subsystem, operating systems, and device drivers make the higher improvements of performance. Therefore, users and developers of graphics engineering workstations should apply it for the optimized systems for 3D CAD applications.๏ผ‘. ์„œ๋ก  = 1 ๏ผ‘.๏ผ‘. ์—ฐ๊ตฌ ๋ฐฐ๊ฒฝ = 1 ๏ผ‘.๏ผ’. ์—ฐ๊ตฌ ๋ชฉ์  = 2 ๏ผ‘.๏ผ“. ์—ฐ๊ตฌ ๋ฐฉ๋ฒ• = 3 ๏ผ’. ๋งˆ์ดํฌ๋กœํ”„๋กœ์„ธ์„œ ๊ตฌ์„ฑ์— ๋”ฐ๋ฅธ 3D ๊ทธ๋ž˜ํ”ฝ์Šค ์„ฑ๋Šฅ ๋ณ€ํ™” = 10 ๏ผ’.๏ผ‘.
