| Abstract | Point based rendering can simulate global illumination phenomenon fast and is widely used in movie production. This paper proposes a faster point based global illumination algorithm compared with the standard one. During our algorithm, the shading points generated by ray tracing are clustered in to groups. When doing point based rendering, the indirect illumination of each group's center point is computed instead of each shading point. We use an error strategy to make the indirect illumination compute adaptively. This method is several times faster than the standard point based global illumination method, while preserves high rendering quality. What's more, we implement our algorithm on GPU. In order to improve parallelism, we design a GPU-based cluster method and then implement the point based rendering process on GPU. The speed is times faster compared with the CPU one. |

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.
