Design And Realize Of 3D Special Carton CAD Software

Carton package become more and more important in the modern package industry for its low-cost, fit-printing and recycle. Applying CAD technology to carton package will promote the efficiency, improve the quality of package carton design, and accelerate the development of package industry.The article focuses on the mini-present package carton system, study the 3D special carton CAD software on the platform of Visual C++, and make use of OpenGL's graphics processing technology to realize the software's performance. In detail, the article utilizes graphics-modeling to design 2D carton parameterized structure, realizes outer upholstery design via texture-map,bitmap operation and lighting, puts forward a method of auto-folding carton based on stacks, and realizes the 2D-To-3D cartoon by double buffer, shows 3D carton from different viewing by the projective and view port transformation. The software is coded by OOP, and wraps the four classes of scene-setting, camera, carton and printing by sorting and abstracting the performance of OpenGL, carton fixtures, screen-snatching process.The 3D special carton CAD software is performed perfectly from 2D to 3D, can export the plane unfolding carton,texture map carton and solid folding carton, can show carton optimally by choosing the viewing,background color,lighting,plane or linear model, and show the auto-folding cartoon especially. Besides, the successor can add codes to improve software easily because of the merit of OOP. There are four classes such as scene-setting, camera, carton and printing to be reused.
