I am trying to plot points on the Bloch sphere using GLMakie, but I get white lines around the lines I use to draw the sphere:
Is there anything I can do to fix this? The script I used to generate the plot is below. I use lines! to draw contours of the sphere, and surface! to draw the transparent sphere.
using GLMakie
function bloch_sphere()
fig = Figure()
ax = Axis3(fig[1, 1], aspect = :data, azimuth = pi/6, elevation = pi/8)
horizontal_circle = [Point3f(cospi(x), sinpi(x), 0) for x in LinRange(0,2,100)]
vertical_circle = [Point3f(cospi(x), 0, sinpi(x)) for x in LinRange(0,2,100)]
n = 50
sx = zeros(n,n)
sy = zeros(n,n)
sz = zeros(n,n)
φs = LinRange(0, 2pi, n)
θs = LinRange(0, pi, n)
for i in 1:n
for j in 1:n
sx[i,j] = cos(φs[i])*sin(θs[j])
sy[i,j] = sin(φs[i])*sin(θs[j])
sz[i,j] = cos(θs[j])
end
end
surface!(ax, sx, sy, sz, color=fill(:gray, n, n), alpha=0.5, transparency=true,
invert_normals=true)
lines!(ax, horizontal_circle, color=:black)
lines!(ax, vertical_circle, color=:black)
lines!(ax, [Point3f(-1,0,0), Point3f(1,0,0)], color=:black)
lines!(ax, [Point3f(0,-1,0), Point3f(0,1,0)], color=:black)
limits!(ax, -1.1, 1.1, -1.1, 1.1, -1.1, 1.1)
fig
end
fig = bloch_sphere()
