| Abstract | A comprehensive 3-D real-time computer animation system is based upon a broad range of research activities in the field of computer graphics. In many ways the requirements for such a system are more challenging and complex than for other graphics systems. This is particularly true if one builds a language and a system which is truly user oriented and which has viable production capabilities for researchers and film makers. Too often systems which are the result of a research experiment in hardware or software design do not go beyond a beautiful demonstration of potentialities. Such experimentation is essential to advance the state of knowledge but if computer animation is to become a new research and production instrument we must, in addition, provide more examples of useable systems.Although each of the following topics are aspects of a real-time animation environment deserving a detailed explanation, they will be dealt with in a way to introduce to the reader basic requirements and problems. The topics are:I. STATE OF THE ART SYSTEMS, AND LANGUAGES• Used as references and as a basis of comparison.II. AN ANIMATION ENVIRONMENT• Several systems and languages are being implemented to run under RSX-11/D on our PDP-11/45 computer.A. VISIBLE SURFACE SYSTEM• Allan Myers' algorithm• VILAN (VIsual LANguage)B. GRAPHICS SUPPORT SYSTEM• Manfred Knemeyer's system for handling hardware devices, data structures, management of transformations and time, and memory management for the graphics buffer.C. ANIMA• A new graphics programming language has been designed and is being implemented.D. DATA GENERATION SYSTEM• Some approaches to problems are briefly discussed.III. DISPLAY HARDWARE AND GRAPHICS ALGORITHMS• The problems presented by the order of transformations in an algorithm are briefly described.IV. HIGH PERFORMANCE GRAPHICS• some speculations. |

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.
