Welcome to the flagtrafo, the flag transformation web application!
This application shows different transformations of flags in the projective space \(\mathbb{RP}^2\). Draw flags by yourself, transform them using the eruption flow, the shear flow and the bulge flow, and generate convex sets by iterative reflections.
We have a brief mathematical introduction about the subject, you can read some tricks on how to use the application, or simply
