Standardize IIF.Position{N}

[dehann]

Why not consolidate:

• IIF.ContinuousScalar == Position1 == Position{1}
• RoME.Point2 == Position2 == Position{2}
• RoME.Point3 == Position3 == Position{3}

RoME.Point2 and RoME.Point3 already have name conflicts with JuliaGeometry. ContinuousScalar seems out on its own.

Added benefit is users can then happily build higher dimensional stuff with Position{4}, etc. It's then very likely that many use cases fall under Manifolds.TranslationGroup(N) and IIF.Position{N}.

💯 agreed! Can we do these as aliases and then deprecate the old naming over time?

[dehann]

Yes, full and healthy deprecation cycle should be easy to do here.

[dehann]

In Julia world we should be able to just use

@deprecate Point2(w...) Position2(w...)

[dehann]

and probably always keep the aliases:

const Position2 = Position{2}

[dehann]

Just adding technical detail:

getManifold(::Position{N}) where N = Manifolds.TranslationGroup(N)

IIF.ContinuousScalar == Position1 == Position{1}

Scalar is a good generic name for me for applications that aren't spatial.

I like Point{N} more than Position{N}, but am fine with both.
