| Abstract | Since product concepts are frequently changed in the early stage of design, the creation of its rough models is useful for communication among the design team. In this paper, we propose modeling operations based on a volume-based cut-and-paste method for generating rough 3D models using existing 3D models. Cut-and-paste editing extracts a characteristic feature from a source model and copies it to a target model. Our method allows pasting a wide variety of features that may have overhangs and handles, while most existing methods cannot manage such shapes. To realize such a volume-based cut-and-paste technique, this paper introduces a new method that consists of mesh segmentation and surface/volume fitting. In our method, a feature region and its surrounding area are separated from the user-specified area, and they are used for generating a parametric volume that involves the feature region. In feature pasting, parametric volumes are deformed and pasted to the target model and then features inside the volume are adaptively deformed and pasted to the target. On the basis of this cut-and-paste method, we propose modeling operations that enable feature registration, feature removal, feature pasting, and texture pasting. These operations were implemented and demonstrated using example models. The result shows our operations can effectively generate new models by removing and reusing partial shapes in existing models. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
