The National Centre for Software Technology is an autonomous research and development institution of the government of India. It is a centre for excellence in software technology and related computer science areas. It carries out research in a number of disciplines such as databases and knowledge engineering, artificial intelligence, computer networking and Internet, software engineering and graphics and CAD.The graphics and CAD division of the centre has been active in this field since the early seventies and is one of the oldest and well-established research groups in this area in India. The current group numbers more than 20 graphics researchers with about 10 interdisciplinary associates in areas like visual design and communication, digital architecture, calligraphy, animation and linguistics.In the very early years, the focus was on graphics and CAD for electronic design, (PCBs, IC Mask layouts, etc.) By the mid seventies, the emphasis shifted to core graphics systems with 3D support. A number of commercially viable packages, such as IndoGKS and IndoPHIGS, based on international standards, were developed collaboratively with the industrial partners and sold worldwide. Over the past 15 years the group has been very active in 3D graphics and computer aided geometric design. A parallel track right from the mid seventies has been electronic publishing with particular emphasis on software architectures for dealing with the complexity of multiple scripts and languages in the country. In each of these subfields the group has undertaken high end implementation projects for end use and distribution, and also carried out substantive fundamental research that has found its way in the form of research publications in prestigious international journals and conferences.For the remainder of this article, we provide a brief overview of some recent research work. For more details on the division's activities and publications, the interested reader is referred to the following Web site: http:://www.ncst.ernet.in/~graphics.
