GelViz is a custom-built tool for visualizing simulated gel networks using OpenGL, developed in a span of two months in 2015 for Emanuela Del Gado's research group at Georgetown University.
The tool allows more careful exploration of the rheological and structural properties of simulated gels under shear stresses, and can export POV-Ray files to generate publication-quality figures and animations.
The tool was able to reveal the novel fact that most of the stress is supported by a handful of molecular chains in the gels, as in the video below. This inspired my research into correlations between topological and rheological properties of the gel network, although I couldn't find any during my short research internship.
GelViz was used to generate figures for Medhi Bouzid's article on Nature Communications.
Animation showing how during a shear transformation, the stresses in the gel network concentrate into a few key structures which eventually break, and the stress is redistributed throughout the network. GelViz was designed for arbitrary association of rendering parameters to data, which allowed us to reveal this behavior.
The idea behind GelViz was to allow arbitrary mapping of simulated data into various independent visualization parameters and primitives, such as separate color components in various color spaces, transparency, bond thickness, displacement vectors, relative speeds, etc.
It was developed in Python and OpenGL. Unfortunately, my internship was too short to fully optimize the software.
GelViz hasn't been released to the public, as it was made for Georgetown University. However, you may see the full documentation for examples of how it works and what it is capable of doing.
