“计算机图形是使用计算机创建的图片和电影。“随着图形即将闭合虚拟和物理现实之间以及从数字设计到制造的循环，维基百科关于计算机图形学条目的开头句变得越来越过时。这是一种新趋势吗？几何建模是计算机图形学的一个分支，随着计算机辅助制造的出现，其目的是通过从设计到生产的完全数字化工作流程来提高生产率，这是工业需求的推动力。几何建模的研究已经非常成功地为3D设计系统创建了各种各样的形状建模功能。数字形状设计的可能性几乎是无限的，并且对于“图片和电影”的创作非常有效。“但该领域是否实现了制造业的目标？我对此并不信服，因为纯粹的几何驱动的形状建模在走向工程和制造时会产生瓶颈。
" Computer graphics are pictures and movies created using computers." This opening sentence from Wikipedia's entry on computer graphics becomes increasingly outdated as graphics is about to close the loop between virtual and physical reality and from digital design to fabrication. Is this a new trend? Not quite, but the magnitude of the current development and the potential impact may be bigger than ever before.Geometric modeling, a subfield of computer graphics, has been motivated by industrial needs at the advent of computer-aided manufacturing, aiming at increased productivity via a completely digital workflow from design to production. Research in geometric modeling has been highly successful in creating a huge variety of shape modeling functionalities for 3D-design systems. The possibilities for digital shape design are almost unlimited and highly effective for the creation of" pictures and movies." But did the field achieve the goals toward manufacturing? I am not convinced here, since purely geometry-driven shape modeling creates bottlenecks when moving toward engineering and fabrication.
