| Abstract | Progressive mesh streaming enables users to view 3D meshes over the network with increasing level of details, by sending coarse version of the meshes initially, followed by a series of refinements. To optimally increase the rendered mesh quality, refinements should be sent in descending order of their visual contributions based on the user's viewpoint. A common approach is to let the sender decide this sending order, but the computational cost of making this decision prohibits such sender-driven approach from scaling to large number of clients. To improve scalability, we propose a receiver-driven protocol, in which the receiver decides the sending order and explicitly requests the refinements, while the sender simply sends the data requested. The sending order is computed at the receiver by estimating the visibility and visual contributions of the refinements, even before receiving them, with the help of GPU. Experiments show that our protocol reduces the CPU cost of the sender by 24% and the outgoing traffic of the sender by 40%. |

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.
