[eigen] Using a Transformation as mapped expression type

[Janos Meny <janos.meny@xxxxxxxxxxxxxx>]

Hey,

Why is it not possible to do something like this:

Matrix4f id = Matrix4f::Identity();

Map<Affine3f> map(id.data());

Apparently the Transformation class does not model the dense public interface, so it is not "mappable". But isnt the Transformation class just a wrapper around a static dense matrix? Couldnt it therefore just pass through the stride, size etc. from the underlying dense matrix type?

Best regards

Janos
