| Abstract | Graph rotation system is introduced recently as a new shape modeling method. It can guarantee the 2-mainfold property of a mesh while we change the topology of the mesh, and has the advantage of the simplicity of creating an artistic graph. A new data structure doubly linked face list is proposed, which can implement the operations of graph rotation system efficiently. However, the original edge operations of it cannot change the number of vertices of a mesh. Using point-sphere, the operations of edge can change the number, but the efficiency is not high. In this paper, the edge operations are modified to improve the efficiency. With this improvement, the algorithm of Catmull-Clark scheme based on graph rotation system is given. At the same time, an interactive shape modeling system based on graph rotation system is given. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
