An Efficient Central Path Algorithm for Virtual Navigation
Found in: Computer Graphics International Conference
By Parag Chaudhuri, Rohit Khandekar, Deepak Sethi, Prem Kalra
Issue Date:June 2004
pp. 188-195
We give an efficient, scalable, and simple algorithm for computation of a central path for navigation in closed virtual environments. The algorithm requires less pre-processing and produces paths of high visual fidelity. The algorithm enables computing pat...
 
GPU-Based Ray Tracing of Splats
Found in: Pacific Conference on Computer Graphics and Applications
By Rhushabh Goradia, Sriram Kashyap, Parag Chaudhuri, Sharat Chandran
Issue Date:September 2010
pp. 101-108
When it comes to rendering models available as points, rather than meshes, splats are a common intermediate internal representation. In this paper we further the state of the art by ray tracing splats to produce expected effects such as reflections, refrac...
 
Making Them Remember—Emotional Virtual Characters with Memory
Found in: IEEE Computer Graphics and Applications
By Zerrin Kasap, Maher Ben Moussa, Parag Chaudhuri, Nadia Magnenat-Thalmann
Issue Date:March 2009
pp. 20-29
The search for the perfect virtual character is on, but the moment users interact with characters, any illusion that we've found it is broken. Adding memory capabilities to models of human emotions, personality, and behavior traits is a step toward a more ...
 
Local manipulation of image layers using standard image processing primitives
Found in: Proceedings of the Seventh Indian Conference on Computer Vision, Graphics and Image Processing (ICVGIP '10)
By Niranjan Mujumdar, Parag Chaudhuri, Sanju Maliakal, Satish Kumar Chavan, Sweta Malankar
Issue Date:December 2010
pp. 259-266
In any modern, standard image manipulation program, images are made up of multiple layers ordered on top of each other in a user defined sequence. A layer is a collection of graphical objects (like masks and image patches). Each layer can be edited separat...
     
Implicit surface octrees for ray tracing point models
Found in: Proceedings of the Seventh Indian Conference on Computer Vision, Graphics and Image Processing (ICVGIP '10)
By Parag Chaudhuri, Rhushabh Goradia, Sharat Chandran, Sriram Kashyap
Issue Date:December 2010
pp. 227-234
Point-based representations of objects have been used as modeling alternatives to the almost ubiquitous quads or triangles. However, our ability to render these points has not matched their polygonal counterparts when we consider both rendering time and so...
     
Real time ray tracing of point-based models
Found in: Proceedings of the 2010 ACM SIGGRAPH symposium on Interactive 3D Graphics and Games (I3D '10)
By Parag Chaudhuri, Rhushabh Goradia, Sharat Chandran, Sriram Kashyap
Issue Date:February 2010
pp. 1-1
Mirroring the development of rendering algorithms for polygonal models, z-buffer style rendering for point-based models has given way recently to more advanced methods. A fast raycasting based approach [Wald and Seidel 2005] shows shadows, but does not dem...
