I am constrained by equilateral triangles to mesh the geometry because of the equations that I have to solve the PDE on this mesh.

I tried to solve this meshing problem by first generating an equilateral grid, then test for all the points that are inside the geometry to be meshed or on her boundary, then I am having difficulties to get all the edges that there both ends are part of the set of points that had extracted in the first step.

the picture above show what i want to do, after that the more the grid is fine the more good the geometry is represented by the mesh.

With equilateral triangles, you can mesh only very special objects.

(e.g. if your object is a polyhedron, you need angles of all faces to be 60 degrees
+ hypotheses on lengths of edges)
