| Abstract | In this paper, we present an efficient algorithm to generate tetrahedral meshes from surface models. Our algorithm first subdivides the axis-aligned bounding box of a surface model into a number of uniform tetrahedra, and then generates an initial indention mesh after removing all the tetrahedra outside the surface model by employing a signed distance function, defined by the vertices of the surface model. Subsequently, our algorithm deals with the rough indention mesh according to the relationship between the surface model and the vertices of the tetrahedra bestriding the mesh surface. Finally, the algorithm uses Laplacian smoothing operator to improve the quality of the tetrahedral mesh. Results show that the volume mesh models created by our algorithm have smooth boundary and high-quality interior cells. |

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.
