| Abstract | A hybrid algorithm for fast drawing ellipse is proposed in this paper. The algorithm is established based on the observation that each quarter ellipse is composed of three regions, and only one kind of primitive appears in one region, such as vertical segment, discrete point pair, and horizontal segment. Among this, the lengths of the vertical and horizontal segments are calculated with double-step iteration by redefining decision parameters, and the patterns of the discrete point pairs may be decided in a similar manner. Every primitive is outputted as a one-time operation. The experiment results show that on average only 3∼4 times basic operations are consumed in once pixel selection, and then the ellipse drawing speed can be almost doubled comparing with that of the classic middle-point algorithm, and is also faster than other presented ones. |

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.
