Welcome!
I usually use a Node to update the scene. This example works for me:
using GLMakie
n=100;
function meshgrid(vx::AbstractVector{T}, vy::AbstractVector{T},
vz::AbstractVector{T}) where T
m, n, o = length(vy), length(vx), length(vz)
vx = reshape(vx, 1, n, 1)
vy = reshape(vy, m, 1, 1)
vz = reshape(vz, 1, 1, o)
om = fill(1, m)
on = fill(1, n)
oo = fill(1, o)
(vx[om, :, oo], vy[:, on, oo], vz[om, on, :])
end
x = range(0,1,length=n);
X,Y,Z = meshgrid(x,x,x);
vrt = sin.(2pi*X) .+ Y .- Z.^2*(rand()+im*rand());
vrtx = zeros(n,n,n,n)
for i=1:n
vrtx[i,:,:,:] = real.(vrt.*exp(im*2pi*i/n))
end
dat = Node{Array{Float64,3}}(vrtx[1,:,:,:])
scene=contour(dat,alpha=0.2,colorrange=[-1,1],colormap=:balance,levels=[-0.5,0.5])
record(scene, "/tmp/kir.mp4") do io
for i=1:n
dat[]=vrtx[i,:,:,:]
recordframe!(io)
end
end
By the way: There are some tips and tricks how to make it easier for others to help you. For example you can format your code and it would be easier if you give an example that works (we don’t have your sample_vrtx_1.mat, needed to run your code).
