Hello, A few weeks ago, I wrote because I was having troubles with ruled surfaces in Gmsh 2.6. I had some triangular patches that worked well in 2.5 but were too curvy in 2.6. I finally figured out how to revert Gmsh 2.6 ruled surface interpolation of triangular patches back to that of 2.5 so that I can mesh my geometry with in 2.6. One must change GeoInterpolation.cpp AND gmshEdge::reparamOnFace().
Anyway, I think you should keep the old style of triangular ruled surface interpolation as an option, at least. I can see how both approaches could be useful in different situations. However, I think it is important to allow meshing of a simple curved triangular patch without such such strong curvature--curvature which is demonstrated by running the attached file in Gmsh 2.6.
