Hello everyone,

I’m trying to use a `mesh3d` as a drop in for `plot_trisurf`, but am struggling to get the same functionality. The difference looks like this:

```julia
plot_trisurf(X, Y, Z)

mesh3d(X, Y, Z, connections=(i, j, k))

```

And I’m not quite clear on where the `connections` tuple needs to come from. All the examples I see use hard coded values - but is there a way to autogenerate this to use `mesh3d`?
