面向移动终端的三维CAD模型面片生成方法
3D CAD Model Patch Generation Method in Mobile Terminal
摘要
Abstract
To improve the display efficiency in the mobile terminal and the display accuracy of model detail, this paper proposes a novel algorithm for 3D CAD model patch generation based on type hierarchy and object graph element. By extracting the database information such as the type and shape attributes of models, 3D CAD models are repre-sented by shape classification tree. The scale coefficient is estimated by 0-1 normalization method for classification tree node of interactive selection. After estimating the scale coefficient, the display accuracy of the model is con-firmed and 3D CAD model patch is generated. Finally, this paper proposes a 3D CAD model display system in mo-bile terminal, and carries out the experiments on 3D CAD model patch generation. The experimental results prove the feasibility and effectiveness of this 3D CAD model patch generation method.关键词
