| Abstract | Interactive entertainment has long been one of the driving factors behind architectural innovation, pushing the boundaries of computing to achieve ever more realistic virtual experiences. Future entertainment applications will feature robust physics modeling to enable on-the-fly content creation. However, application designers must provide at least 30 graphical frames per second to provide the illusion of visual continuity. This constraint directly impacts the physics engine, which must deliver the results of physical interactions in the virtual world at a fraction of this frame rate. With more sophisticated applications combining massive numbers of complex entities, the cost of robust physics simulation will easily exceed the capability of today's most power machines.This work explores the characteristics of real-time physics simulation, and proposes a suite of future-thinking benchmarks stressing different situations that represent the demands of future interactive entertainment. With this suite, we then explore techniques to help meet these demands, including parallel execution, a fast estimation approach that self-regulates error, and a value prediction technique that is allowed to get "close enough" to the real value. We demonstrate that parallel execution together with the proposed fast estimation approach can satisfy the demands of nearly all of the PhysicsBench suite. |

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.
