MathGL3d does offer many impressive features,but it is not the solution to every graphics related problem! Launching an external program is not something you do casually, and if you are designing code for others to use, you can not assume that they have MathGL3D available too..So don't rely too heavily on any Mathematica package, if there is a simple solution available.
