mtsFrm4x4

[marcinbalicki]

Ran into a surprising data type mismatch issue - last line fails with "no viable overload = " on mac OS. Any thoughts?

mtsFrm4x4 goalFrm;
mtsFrm4x4 currentFrm;
mtsFrm4x4 diffFrm;
diffFrm.Translation() =  goalFrm.Translation() - currentFrm.Translation();
diffFrm.Rotation() = goalFrm.Rotation() * currentFrm.Rotation().Transpose();

The unsightly workaround is below :
diffFrm.Rotation().Assign(goalFrm.Rotation() * currentFrm.Rotation().Transpose());
