StructArrays interface for points about geometrybasics.jl HOT 8 OPEN

Alright, that's fair! I think GeometryBasics should just support a convenience constructor for this :)

from geometrybasics.jl.

I've commented over at JuliaArrays/StructArrays.jl#126 (comment). It can be made to work already if one calls the constructor in a slightly different way, and one gets a

StructArray(data::StructArray(::Array{Float32,1}, ::Array{Float32,1}, ::Array{Float32,1}))

from geometrybasics.jl.

it would be useful to have mutable StructArrays of point

Why? Can you give a concrete example?

from geometrybasics.jl.

Transformations with the Proj library come to mind - it accepts separate arrays of x, y, and z, and the most efficient mode of operation is to operate in place. Having 3 arrays of x, y, and z which could be transformed in place would be pretty useful, especially when you get into >500K points.

I thought this was trivially supported, but can't find the correct constructor right now :D Evidence, that this should be made easier & documented...

After talking with @piever it may be a bug:
JuliaArrays/StructArrays.jl#126

from geometrybasics.jl.

Well I tried it a while ago...the issue is that we store the data in a tuple, so StructArrays just makes an array of tuples, which is useless for this. We need to define our own static schema which takes, for example, a Point3f0, and maps it to x, y, and z (or x1, x2 and x3, but that's uglier)...

Yeah, but this is supposed to "just work"... So lets see if we can have this fixed ;)
