Biography and Interests

Dr Reddy worked in the area of terrain visualization. This work involved the real-time display of massive terrain databases that are distributed over wide-area networks. Dr Reddy now works for Pixar Animation Studios. His research interests include level of detail, visual perception, and computer graphics. His doctoral research involved the application of models of visual perception to real-time computer graphics systems, enabling the selection of level of detail based upon measures of human perception. He received his B.Sc. from the University of Strathclyde and his Ph.D. from the University of Edinburgh, UK. He served for two years on the Board of Directors of the Web3D Consortium and chaired the GeoVRML Working Group. Dr Reddy is co-author of a book called Level of Detail for 3D Graphics, published by Morgan Kaufmann Publishers (see LODBook.com).

Past Projects

	Battle Assessment and Data Dissemination (BADD) Provided three-dimensional (3-D) site model data for integration with terrain data from other project participants, and provided our terrain visualization system, TerraVision, as an alternative visualization technology.
	Creating and Visualizing the Digital Earth Developing a connected suite of technologies with the vision of enabling a massive, scalable, and open model of the planet where millions of users can interact with vast quantities of geographically referenced data over the Web
	Multidimensional Applications and Gigabit Internet Consortium (MAGIC) MAGIC established a standards-based, gigabit internetworking testbed to support research and development for next generation networking technologies, and developed a defense-related application that required massive amounts of remotely stored and processed data in real time.
	Multidimensional Applications and Gigabit Internet Consortium (MAGIC) II MAGIC II consisted of a consortium of industry and academic institutions building a very general paradigm in which high-performance computing, storage, and communications are used to provide rapid access to massive amounts of data over the Internet

Software

	DEM to GeoVRML Converter DEM2GeoEG is a program to convert USGS Digital Elevation Model (DEM) data into a VRML .wrl file that uses the GeoVRML 1.0 GeoElevationGrid. The GeoElevationGrid is a version of the standard ElevationGrid but it lets you georeference the data to geographic coordinate systems such as UTM (Universal Transverse Mercator).
	GeoTransform Package This package provides efficient and accurate geographic coordinate transformations in the Java language. It includes support for geodetic (lat/long), geocentric, UTM, lambert conformal conic, mercator, and OSGB coordinate systems.
	GeoVRML GeoVRML is an extension to the Virtual Reality Modeling Language (VRML97) to support geographic applications.
	TerraVision TerraVision is a distributed, interactive terrain visualization system developed by SRI International. It allows users to navigate, in real time, through a 3-D graphical representation of a real landscape created from elevation data and aerial images of that landscape. All data can be distributed over the Web and support is provided for overlaying GeoVRML 3D models.
	tsmApi Library The Tile Set Manager (TSM) Application Programming Interface (API) is an Open Source library of high level C functions for reading, writing, and processing the terrain data used by the TerraVision terrain visualization application.
