摘要：Model resizing is very useful when creating new models based on existing ones or applying models in different scenes. In order to determine the features to be preserved, recent resizing techniques have focused on mesh analysis to get low-level characteristics like edge and face vulnerability to scale, or high-level characteristics like mesh symmetry and parallelism. We observe that the extraction of such mesh information is time-consuming and very limited, so we let the user choose the features to be maintained, and provide the user with a flexible selection mode based on a simple mesh segmentation. Our method can precisely preserve the user-specified features and maintain its boundary continuity, meeting the requirements of engineering applications. The method resizes the model by a spacedeformation technique, so it can handle complex models with multiple connected components and intertwined features. A number of experimental results have shown that our approach has obtained pleasing results and outperformed the previous approaches. Copyright © 2014 Binary Information Press.
