Updated instructions for Makie + Pluto

What are the most up to date instructions to visualize WGLMakie scenes inside a Pluto notebook?

The link isn’t loading for me, perhaps a temporary connection issue?

If you have slow internet, it may be a bit slow to load :sweat_smile: It has quite a bit of states cached for the offline interactivity feature.

I want to produce web pages with a bit of text, code, some LaTeX maths and plots. I’ve previously used weave.jl to produce pdfs in Tufte style. But now I’d like to chuck in some interactive makie plots e.g. see how a stream plot changes with new parameter values.

Given that I have no background in html or Java script (but obviously happy to learn on the job), what do you think would be the simplest method to achieve this? I guess Documenter would be much the same as Weave.

This seems to be the most update to date link.

Here is a quick example I adapted from the Lorenz example.

Cell 1:

begin
	using WGLMakie
	using Bonito
	using Makie
end

Cell 2

begin
	WGLMakie.activate!()
	Page()
	Base.@kwdef mutable struct Lorenz
	    dt::Float64 = 0.01
	    σ::Float64 = 10
	    ρ::Float64 = 28
	    β::Float64 = 8/3
	    x::Float64 = 1
	    y::Float64 = 1
	    z::Float64 = 1
	end
	
	function step!(l::Lorenz)
	    dx = l.σ * (l.y - l.x)
	    dy = l.x * (l.ρ - l.z) - l.y
	    dz = l.x * l.y - l.β * l.z
	    l.x += l.dt * dx
	    l.y += l.dt * dy
	    l.z += l.dt * dz
	    Point3f(l.x, l.y, l.z)
	end
end

Cell 3

App() do
	attractor = Lorenz()

	all_points = Point3f[]
	all_colors = Int[]
	
	
	set_theme!(theme_black())

	for frame in 1:360
		for i in 1:50
	        push!(all_points, step!(attractor))
	        push!(all_colors, frame)
	    end
	end

	points = Observable(@view all_points[1:end])
	colors = Observable(@view all_colors[1:end])
	
	fig, ax, l = lines(points, color = colors,
	    colormap = :inferno, transparency = true,
	    axis = (; type = Axis3, protrusions = (0, 0, 0, 0),
	              viewmode = :fit, limits = (-30, 30, -30, 30, 0, 50)))
	scatter!(ax, lift(last, points))
	step_slider = Makie.Slider(fig[2,1], range = 1:length(all_points))
	cam = Camera3D(ax.scene)
	on(step_slider.value) do step
		points[] = @view all_points[1:step]
		colors[] = @view all_colors[1:step]
		#update_cam!(ax.scene, cam, mod(step/length(all_points)*2π, 2π), 0)
	end

	DOM.div(fig)
end

Interactive Figure

This notebook generates the following interactive figure with a slider that progressively shows the steps.
