| Abstract | Dynamic rendering large scale forest is still difficult, since it needs to create, maintain, grow and destruct tens of thousands of plant objects at runtime. This paper deals with this difficulty and presents a scene graph based scheme that allows us to model plants according to their growth stages, organ structures, and level of detail (LOD) requirements. To efficiently manipulate plant objects at runtime, plant growth data are stored in extensible markup language (XML) file, and a parameterized plant builder is developed to load proper plant model into memory and transform it to target appearance with given parameters. In order to decrease the memory consumption, all plant objects in memory are created and managed by plant builder in a centralized way so that plant objects can share textures, drawing states and other resources. By discretizing parameters that is used to create or grow plant objects, plant builder decreases the number of plant objects that really need to create in memory, and accelerates the plant creation and growth speed. |

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.
