I am trying to get a hold on Plots.jl capability to plot meshes. The `mesh3d` seems to be the good choice for that.

With the following example, I manage to plot a uniformly colored mesh with the `plotlyjs` backed.

```julia
using Plots;
plotlyjs();

u1 = LinRange(0, 2 * pi, 100) .* ones(100)'
v1 = (LinRange(0, 2 * pi, 100) .* ones(100)')'
u2 = sin.(u1) .* sin.(v1)
nl, nc = size(u1)

mesh3d(vec(u1), vec(v1), vec(u2))

```

However, the `vertexcolor` parameter that should be used to pass a color to each point seems not to work as `mesh3d(vec(u1), vec(v1), vec(u2), c = :red)` expectedly returns a red mesh, but `mesh3d(vec(u1), vec(v1), vec(u2), c = :red, vertexcolor = vec(u2))` too.  
An attempt to provide a 3-column matrix of numbers in (0-255) failed as well `mesh3d(vec(u1), vec(v1), vec(u2), vertexcolor = rand(size(u2,1),3)*255)`

Does somebody have a clued how this should be done ?

Note : I know I could plot the surface with `surface(LinRange(0, 2 * pi, 100), LinRange(0, 2 * pi, 100),u2)` but it is not the point here because my end goal is to plot a surface with a non rectangular grid, which does not work with `surface`.

Have you figured this out?

Nope. My current solution is to use `Makie` for that which is a bit annoying, as all my other plots are done with `Plots`

No, and I switched all of my plotting recipes to Makie… so I’m leaving this open for others…

I know it is over two years later, but in case someone needs it, here is a solution I got to work with Julia 1.10

```julia
using Plots;
plotlyjs();
u1 = LinRange(0, 2 * pi, 100) .* ones(100)'
v1 = (LinRange(0, 2 * pi, 100) .* ones(100)')'
u2 = sin.(u1) .* sin.(v1)
nl, nc = size(u1)

mesh3d(vec(u1), vec(v1), vec(u2), intensity = vec(u2), color=:buda, showscale=true)

```

Where the colorscale is pulled from: [https://docs.juliaplots.org/latest/generated/colorschemes/](https://docs.juliaplots.org/latest/generated/colorschemes/)

I get the folowing display:
