| Abstract | This paper proposes a novel, yet extremely compact shape representation method. Its main feature is that 3D shapes are represented in terms of functions instead of geometric primitives. Given a set of - typically only a few - specific parameters, the evaluation of such a function results in a model that is one instance of a general shape. Particularly important for the web context with client systems of widely varying rendering performance is the support of a semantic level-of-detail superior to any low-level polygon reduction scheme.The shape description language has the power of a full programming language, but it has an extremely simple syntax. It serves as a ***mesh creation/manipulation language'. It is designed to facilitate the composition of more complex modeling operations out of simpler ones. Thus, it allows to create high-level operators which evaluate to arbitrarily complex, parameterized shapes. The underlying low-level shape representation is a boundary representation mesh in combination with Catmull/Clark subdivision surfaces. |

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.
