Is that possible to convert triangular mesh to simplex mesh?

I want to convert a simplex mesh to triangular mesh on which I can apply some triangular mesh simplification using cgal because simplex mesh simplification is a bit difficult. Is there any example which converts from simplex to traingular?

There is a filter for the opposite, TriangleMeshToSimplexMeshFilter. But you might find more code in this Insight Journal article. That code might need updating.

Thank You.
