Found in: 2013 XXVI SIBGRAPI - Conference on Graphics, Patterns and Images (SIBGRAPI)
By Guilherme Oliveira,Joao Comba,Rafael Torchelsen,Maristela Padilha,Claudio Silva
Issue Date:August 2013
pp. 99-106
The recent widespread of heart rate (HR) monitors is allowing people to measure body response during and after exercise, which produces a collection of time-series on multivariate aspects, such as heartbeat, speed, geolocation, etc. Such monitoring can be ...

<p>Direct visualization of higher-order data avoids the error and overhead introduced by the widely used resampling approach.</p>
Salient Clustering for View-dependent Multiresolution Rendering
Found in: Graphics, Patterns and Images, SIBGRAPI Conference on
By Rodrigo Barni, João Comba, Amitabh Varshney
Issue Date:October 2009
pp. 56-63
Perceptual information is quickly gaining importance in mesh representation, analysis and rendering. User studies, eye tracking and other techniques are able to provide ever more useful insights for many user-centric systems, which form the bulk of compute...
Why Not with the Foot?
Found in: 2011 Brazilian Symposium on Games and Digital Entertainment (SBGAMES)
By Erivaldo Xavier de Lima Filho,Mateus Bisotto Nunes,Joao Comba,Luciana Nedel
Issue Date:November 2011
pp. 270-281
The evolution of graphics hardware in the past decade has made it possible to generate scenes in computer games with a high degree of realism, which in turn, requires richer interactions. However, while the number and complexity of possible interactive tas...

Edge Groups: An Approach to Understanding the Mesh Quality of Marching Methods
Found in: IEEE Transactions on Visualization and Computer Graphics
By carlos dietrich, Carlos Scheidegger, João Comba, Luciana Nedel, Cláudio Silva
Issue Date:November 2008
pp. 1651-1666
Marching Cubes is the most popular isosurface extraction algorithm due to its simplicity, efficiency and robustness. It has been widely studied, improved, and extended. While much early work was concerned with efficiency and correctness issues, lately ther...
A segment-tree based kinetic BSP
Found in: Proceedings of the seventeenth annual symposium on Computational geometry (SCG '01)
By Joao Comba, Leonidas J. Guibas, Mark de Berg
Issue Date:June 2001
pp. 134-140
We present anew technique to maintain a BSP for a set of n moving disj oint segments in the plane. Our kinetic BSP uses O(n log n) storage and it undergoes O(n 2 ) changes in the worst case, assuming that the endpoints of the segments move along bounded-de...
