3-view impostors

Content Provider ACM Digital Library
Author Hardy, Alexandre Venter, Johannes
Abstract In this article we present a new volumetric representation of objects which can be rendered in real-time on modern GPUs. We show how existing polygonal objects are transformed into a volumetric representation involving space carving and height fields. The performance of the rendering algorithm is determined by the screen space area of the volume, and is suitable as an impostor algorithm for objects sufficiently far from the viewer. These 3-view impostors are viewable from any angle and only need to be updated if the object is animated dynamically. 3-View impostors offer a number of advantages over competitive techniques, namely: regular sampling for several views, bounded texture usage, accelerated ray object surface intersection, and more robust handling of thin surfaces.

About National Digital Library of India (NDLI)
NDLI logo

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.
