【摘要】 在基于WEB的协同CAD软件中,模型的显示和拾取是对模型进行分析和编辑的前提和基础。本文研究了ACIS几何平台与外部3D图形库连接的机制,分析了Java3D用于显示的基本图元,提出了一种在ACIS和Java3D之间进行桥接的方法,并在具有自主知识产权的协同CAD系统———WebSuperman中实现。更多还原

【Abstract】 The visualization and picking is the precondition and foundation of analysis and modification for a model in the web-based collaborative CAD software. The mechanism of connecting ACIS with an external graphics sub-system is researched and the basic Java3D primitives of geometry that used in visualization are analyzed in this paper. A new method that bridges ACIS and Java3D Geometric Modeler is approached and implemented in a collaborative CAD prototype system--WebSuperman, which has it’s own intellectual property rights.更多还原
