General Information

I am an Associate Professor of Computer Science at the University of Utah, and a faculty member of the SCI Institute.

Upon arriving at Utah in October 2003, I started the Visualization and Geometric Computing (VGC) group that at any given time includes a number of post-doc, graduate, and undergraduate students. We often also have both short and long-term visitors in our lab.

I received a B.S. in mathematics from the Federal University of Ceara (Brazil), M.S. and Ph.D. degrees in Computer Science from the State University of New York at Stony Brook. Right after graduation I was a post-doc in the applied mathematics & statistics department at Stony Brook.

I spent several years in industry before becoming a full-time faculty member. During this time, I had the opportunity to be officially or un-officially associated with the following institutions: IBM, AT&T, Sandia, LLNL, Stony Brook, OGI, and Princeton.

CP SC 4960 (Spring 2007) - Programming Challenges

CP SC 7940 (Spring 2007) - Scientific Visualization and Geometric Computing Seminar

Software (source code)

http://www.vistrails.org

http://afront.sourceforge.net, by Schreiner, Scheidegger, Fleishman and others.

http://havs.sourceforge.net, implementation of the Hardware-Assisted Visibility Sorting (HAVS) algorithm for rendering unstructured grids, by Callahan, Ikits, and others. Note that there is also a version of the HAVS algorithm implemented in VTK: vtkHAVSVolumeMapper.html.

GPU-based ray caster for Unstructured Meshes, by Bernardon and Comba.

TetMesh Comparator (tmc), for measuring errors between two tet meshes, by Louis Bavoil.

GTB: Graphics Toolbox, includes implementation of Correa's PhD thesis (in particular, iWalk)

GcTin, Greedy-Cuts terrain triangulation.

ZSWEEP, implementation by R. Farias of the ZSWEEP algorithm. Note that Kitware has implemented ZSWEEP in the most recent version of VTK. Here is a link to the class hierarchy: vtkUnstructuredGridVolumeZSweepMapper. I have not tested their implementation against the original one, but this one is certainly easier to use, since it is fully integrated into both VTK and Paraview. I have been told this is the preferred way to generate high-quality images of unstructured grids in VTK.

Raytrace, Unstructured-grid ray tracer, by Bunyk. This has also been implemented into VTK, see vtkUnstructuredGridBunykRayCastFunction

Here is a sample unstructured grid dataset: spx.off

Source code of Wylie et al's vertex program for rendering a tetrahedron. Brian asked me to post this for him, since he did not have a webpage. See their paper at VolVis 2002 for details.

oocsx.m, partial Mathematica implementation of the OoCSx algorithm.
