Gmsh Min Tessellate
This uses a facility in Gmsh to Tessellate Objects to an STL Mesh type Mesh which it then performs a Recombine operation to reduce the complexity of a Mesh. The Gmsh options are the same as for a straight Gmsh operation.
The following images show as examples a recombination of a Cube, Cylinder and more complex Object.
A cube results in six quads rather than twelve triangular Facets
Example of a Cylinder
A Couple of more complex objects

The end result is simpler than an all triangular facets Tessellation.
