Problems with GLMakie

[Mervyn_Larrier]

I’m trying to learn how to use GLMakie having had a lot of success with CairoMakie. But I immediately ran into issues. VSCode is my main text editor, and whereas I’ve never had an issue with CairoMakie, I can’t say the same here. This example comes from the mesh section on the Beautiful Makie website, but I cannot run it. From the closeall() function to the basic geometry types, I keep getting that the functions are undefined. Any help would be greatly appreciated.

using GLMakie, Random, Colors, LinearAlgebra
using GeometryBasics: Cylinder, Pyramid
using Makie
import GeometryBasics
GLMakie.closeall() # close any open screen

Random.seed!(3)

cyl = Cylinder(Point{3, Float64}(1,2,3), Point{3, Float64}(2,3,4), 1.0)
pyr = Pyramid(Point3f(0), 1f0, 1f0)
rectmesh = Rect3(Point3f(-0.5), Vec3f(1))
rectthin = Rect3(Point3f(-1), Vec3f(2,2,0.25))
sphere = Sphere(Point3f(-0.5), 1)
Cone(; quality = 10) = merge([
    Makie._circle(Point3f(0), 0.5f0, Vec3f(0,0,-1), quality),
    Makie._mantle(Point3f(0), Point3f(0,0,1), 0.5f0, 0f0, quality)])
cone = Cone()
rectMesh = GeometryBasics.mesh(rectmesh)
rectThin = GeometryBasics.mesh(rectthin)
cyL = GeometryBasics.mesh(cyl)

cmap = resample_cmap(:Spectral_11, 3*length(rectMesh.position))
colors1 = [cmap[i] for i in 1:3*length(rectMesh.position)]
colors2 = repeat([RGBA(rand(4)...) for v in rectThin.position], 3)
colors3 = repeat([norm(v) for v in cyL.position], 2)[1:62]
markers = [sphere, rectmesh, cyl, pyr, cone]

with_theme(theme_dark()) do
    fig = Figure(size = (1200,800))
    axs = [Axis3(fig[i,j]; aspect = :data, perspectiveness = 0.5)
        for j in 1:3, i in 1:2]
    mesh!(axs[1], sphere, color = :white)
    mesh!(axs[2], rectmesh, color = colors1)
    mesh!(axs[3], pyr; color = (:dodgerblue, 0.85))
    wireframe!(axs[3], pyr; color = :grey90)
    mesh!(axs[4], cyl; color = colors3,
        colormap = :diverging_tritanopic_cwr_75_98_c20_n256)
    mesh!(axs[5], cone; transparency = true)
    wireframe!(axs[5], cone; color = :grey90, linewidth = 0.5)
    mesh!(axs[6], rectthin; color = colors2, shading = NoShading)
    [meshscatter!(axs[6], Point3f(1.5rand(3) .- 0.5); marker = markers[i],
        markersize = 0.25) for i in 1:5]
    fig
end

Makie._circle and Makie._mantle are the culprits. I’m not sure what, if anything, was supposed to replace them. The figure can be reproduced with:

using GeometryBasics
using LinearAlgebra

function Cone(; quality = 10)
    # Create base circle points
    base_radius = 0.5f0
    base_points = Point3f[]
    for i in 0:quality-1
        angle = 2π * i / quality
        x = base_radius * cos(angle)
        y = base_radius * sin(angle)
        push!(base_points, Point3f(x, y, 0))
    end
    
    # Apex point
    apex = Point3f(0, 0, 1)
    
    # Create faces connecting base to apex
    faces = TriangleFace{Int}[]
    for i in 1:quality
        next_i = (i % quality) + 1
        # Triangle: base point i, base point next, apex
        push!(faces, TriangleFace(i, next_i, quality + 1))
    end
    
    # Base circle face
    base_face_indices = collect(1:quality)
    for i in 2:quality-1
        push!(faces, TriangleFace(1, i, i + 1))
    end
    
    # Combine all points
    all_points = vcat(base_points, [apex])
    
    return GeometryBasics.Mesh(all_points, faces)
end

That tidy bit of code goes to replace the Cone function, right? I run into issues before this juncture. I should point out that when I defined the function in its own script and ran it, it seemed to compile fine. No errors were thrown and the function appeared defined with one function. Here’s what I’m seeing on my end:
