I'm sorry for the persistence, but does anyone have any insight on this problem?

Below is an image sequence of what could happen to a grain. (1) Simple, Convex Grain (2) Non-Convex Grain (3) Complex Grain (self-intersection)

All of the grains are initially simple and convex (ie. created using a Voronoi tessellation) . During the simulation, many become non-convex (one or more reflex angles are created) due to deformation. And some could even become complex (have self-intersections). This is what I need to check for...

Hi, I am working on a simulation code that simulates the deformation of sand grains in 2D. The sand grains are modeled as simple polygons. However, during the simulation the grains can deform to create non-convex vertices. Further more, when deformation becomes extreme, there is a possibility...
