I graduated from the University of California Riverside (UCR) in the Computer Science and Engineering department (2005). I was doing research at the Riverside Graphics Lab (RGL) under the guidance of Dr. Victor Zordan, headmaster of RGL.
I currently work in Mexico as a Sr. Programmer in the systems area of the Instituto de Ciencias Fisicas (Physics Science Research Center) of the Natinal University (UNAM). If you are interested please see my CV at the end of the page.
RESEARCH AND WORK INTEREST:
My masters project was on
the study and creation of virtual human Eyes. This was done in C++ and OpenGL
using ray tracing technique and mathematical modeling to create the human eye in
a virtual environment. The project allows for a lot of flexibility including
different types of irises, colours and physical properties. These images show
different properties in the eyes, such as dilated, contracted, different colour
and the iris alone. Click on the thumbnail to see a bigger image. The pdf file
of the proyect report is also available in the link below.
I created an animation of the
dilation of the iris. This was done using a skeleton made of springs and
simulating the physical movement of them. This was focused on the movement and
not on the looks. The visualization was done using Maya® and the simulation in
C. Animation 1
Animation 2
My previous project was the animation of solid
deformable objects in 3-D using spring mesh particle systems. I am also
interested in all real time animations from movies to games.
You may have the technical report of the real time spring-mesh
here (PDF).

EDUCATION:
I started my Bachelors in
Sciences at the Universidad
Autonoma de Morelos
in Mexico.
When undergraduate I was the first student in the joint program between Mexico and UCR for Computer Science
undergraduate students which
allowed me to do the second half of my Bachelors at UCRiverside.
Now I recently graduated from the Masters in
Computer Science program at UCRiverside under the Mexican National Council for Science and
Technology (CONACyT) scholarship in agreement with The Institute for
Mexico and the US (UC-MexUS).
