I would like to pass a vector of 3D points:

```julia
v = Vector{Point3f0}(undef, 10)

```

to scatter plot. Do I have to separate it into x, y and z columns first and call:

```julia
scene = scatter(x, y, z, color = :red, markersize = 0.02)

```

or there is a simpler way?

BTW, why name the type `Point3f0` instead of `Point3f`?

I think this was chosen in reference to the `f0` suffix for Float32 literals:

```julia
julia> typeof(1.2)
Float64

julia> typeof(1.2f0)
Float32

```

But I agree it’s confusing, since the `0` in `f0` is incidental… `1.2f3` is also valid syntax for a Float32. So `Point3f` would make more sense, and it is also more usual. These types are defined in [GitHub - JuliaGeometry/GeometryBasics.jl: Basic Geometry Types](https://github.com/JuliaGeometry/GeometryBasics.jl) . Maybe it would be worth filing an issue to suggest changing it.

It should just work to pass the Vector of points to the plotting function?

Indeed it does:

```julia
scatter(rand(Point3f0, 10), color = :red, markersize = 0.02)

```

I’m just learning my ABCs and asking silly questions.

No worries, I was just wondering given the way you phrased the question whether you had encountered a bug

Out of curiosity, how did you know this would work? I can’t find any example using this syntax… I would have tried `scatter([x y z])` (which fails) but wouldn’t have guessed `scatter(Point3f0.(x,y,z))`). It also seems hard to find it by reading [https://makie.juliaplots.org/stable/signatures.html](https://makie.juliaplots.org/stable/signatures.html)…

I’ve been using Makie for a while, so I just knew. But I don’t know if it’s explicitly mentioned in the docs somewhere
