Need to add alga crate dependency in order to use MatrixN::transform_point

[Jbat1Jumper]

While reading the user guide on Using raw transformation matrices on points and vectors¹, I saw that it mentions the transform_point and transform_vector methods but doesn't say that in order to use them you must bring the alga::linear::Transformation trait to scope. Looking at the source code in the doc and the example² make it clear, but at first it was a little misleading.

I didn't found another way to use those methods that adding the alga crate to my Cargo.toml. So I was thinking, would it be a good idea to reexport the alga::linear::Transformation? Or is it better to leave it like that and just add a comment in the documentation?

I agree the documentation should clarify the fact the alga::linear::Transformation trait must be imported.

For now, I'd prefer not to reexport the trait to keep it clear the abstract traits cone from alga.

Closing this in favor of dimforge/nalgebra.rs#6

Would it make sense to wrap these trait methods as inherent methods for convenience?

[sebcrozet]

That can be considered if that makes it easier to use, yes.

This was fixed by #457. Closing.
