The IEEE Visualization Contest 2012 targets the field of computational material science. The challenge was to develop visualization and interaction methods to answer detect and analyze phase transitions (ferroelectric and polarization domains) in barium titanate. Visualization questions and tasks are how the formation of domains based on atom displacements occurs, which mathematical descriptor can best describe the change of polarization in the vector field, whether there is an evolution in the atoms' trajectory, which could suggest a phase transition, and many more.
The contest aims at demonstrating how novel visualization and interaction techniques from the fore-front of scientific research can help to solve real-world problems of high relevance.
