I have no idea, but it was written by Olivier and I wouldn't trust it (ok, I know this has become cliche in a way...; you can take it as a joke as well). I think the real reason is that for the incremental formulation, you don't need exact rotations since they cost too much and the linearized form is sufficient. Bruno? > > Q3.

What editor/IDE do you use?
