Bug 1129

Summary: Add asAffine() and asProjective() views to MatrixBase or DenseBase
Product: Eigen Reporter: Christoph Hertzberg <chtz>
Component: GeometryAssignee: Nobody <eigen.nobody>

Description Christoph Hertzberg 2015-12-08 17:31:36 UTC
As discussed on IRC, this would return a Transform-object (a to-be-created TransformBase, to be exact) without needing to copy the actual matrix.

This would be equivalent to the .matrix() and .array() views already supported by ArrayBase/MatrixBase.

Bug 192 could be solved simultaneously, since Map<Transform<...> >(ptr) would be equivalent to Map<Matrix<...> >(ptr).asAffine().
Comment 1 Christoph Hertzberg 2019-08-28 07:27:03 UTC
We could also add an .asQuaternion() method.
