Tiresias is an opensource C++ library for visualizing finite element data on triangulated domains. It is built on top of VTK (Visualization Tool Kit). It is designed to give a very simple interface with a finite element code, as it requires the user to supply i.) the reference mapping for each element and ii.) the local nodal values on each element. It then creates a colormapped plot of the data. Since Tiresias visualizes element-by-element, it can visualize nonconforming and conforming finite element data in the same way. A SWIG-generated Python interface is also discussed, and examples are given.
