Note:

  • new fixtures must be convex
  • new fixtures has limited count of points (by default, up to 8). As you can see in the picture, in new fixtures there are +1 points comparing to source fixture.
  • in old box2d versions, you should sure right winding of the points
  • it is not trivial task, to find bottom midle point. For example, I used triangulation for this purposes.
  • crater point can be projection of the contact point to nearest edge. Contact point itself can be somewhere near to edge.
  • there is special case, when crater point is near to corner.
