I want to plot two surfaces in one figure, for example

```julia
using CairoMakie

x = range(-pi, pi, 128)
y = x'
z1 = broadcast((x,y)->cos(x)+cos(y), x,y)
z2 = -1.0.*z1
f,_,_ = surface(x,x,z1; axis=(type=Axis3,),colormap=:jet)
surface!(x,x,z2,colormap=:jet)
f

```

the result is

 ![截屏2025-03-10 16.27.32](https://global.discourse-cdn.com/julialang/original/3X/b/5/b59edb9ec5d52ce8982cae270e31daa13b2ae5a2.png)  
the first surface is covered by the second surface like a 2D plot, but the two surfaces should have intersection as follow (by mathematica)

how to realized above figure by Makie? Thanks in advance!

just do `transparency=true`.

```Julia
x = range(-pi, pi, 128)
y = x'
z1 = broadcast((x,y)->cos(x)+cos(y), x,y)
z2 = -1.0.*z1
f,_,_ = surface(x,x,z1; axis=(type=Axis3,),colormap=:jet, transparency=true)
surface!(x,x,z2,colormap=:jet, transparency=true)
f

```

also, you could add a wireframe, if needed as in [here](https://beautiful.makie.org/dev/examples/3d/surfaces/surface).

`using GLMakie` solve the problem, setting `transparency=true` can make it more beautiful, thx!
