Sorry I don't have much time to follow this development, but it seems that
in the current patch QuaternionWrapper would be only to map a float* (or
double*) as a Quaternion, right ? while other uses of "Wrapper" are to to
wrap any expressions (including a Map<>) as something else (e.g. a
DiagonalMatrix).
So instead of QuaternionWrapper, what about using a specialization of Map
for Quaternion:
template<typename _Scalar, int Alignment>
class Map<Quaternion<_Scalar>, Alignment> : public QuaternionBase<...>
{
// current QuaternionWrapper's code goes here
};
User code would look like:
float data[4];
Map<Quaternionf,Aligned> q(data);
Maybe this look more natural ?
