Skia is pretty cool, I’m not sure how well it works for writing out PDFs and SVGs.
If those work well, I guess it could be a pretty nice replacement for CairoMakie.
If it cant replace it, it will be a bit badly positioned between GLMakie and CairoMakie, so it would make it a bit harder to give clear advice on which backend to use.
Anyways, would be nice to have a prototype and see how it does.
PDFs are no problem at all. The same engine is used when you print a web page. The status for SVG:s are more questionable. There is no export page to SVG functionality in most browsers. Export to SVG exists, but it could contain bugs. I will make a prototype, I am certain it will do well.

Hmmm… so simple things like this no longer seem to work now?
s = Scene(camera=cam3d!)
a = Observable(Point3{Float64}(0.0, 0.0, 0.0))
meshscatter!(s, Point3{Float64}(0.0, 0.0, 0.0), marker=lift(a -> Sphere(a, 1.0), a), markersize=1, space=:data)
a[] = Point3(1.0, 1.0, 1.0) # Update the observable to trigger the meshscatter update
notify(a)
s = Scene(camera=cam3d!)
a = Observable(Point3{Float64}(0.0, 0.0, 0.0))
mesh!(s, lift(a -> Sphere(a, 1.0), a), space=:data)
a[] = Point3(1.0, 1.0, 1.0) # Update the observable to trigger the meshscatter update
notify(a)
The meshscatter! code does not work. However, I don’t know if this is an inconsistency or if, in that case, that would not be an attribute or whatever, but it works well for mesh!
What would be a simple fix to the code if these kinds of Observable updates are what your code relies on? How exactly would you do this with the ComputeGraph pipeline?
(I know I can use the position to be an observable, but what if I want attributes like marker to be automatically updatable, given some other variable updates?)
using GLMakie
# Create a scene
s = Scene(camera=cam3d!)
# Create the meshscatter plot with an initial static marker
plot = meshscatter!(s, Point(0.0, 0.0, 0.0), marker=Sphere(Point(0.0, 0.0, 0.0), 1.0), markersize=1, space=:data)
# Update the marker using Makie.update!
Makie.update!(plot, marker=Sphere(Point3(2.0, 1.0, 1.0), 1.0)) # Does NOT work as expected, the marker is not updated in the scene
Makie.update!(plot, color=:orange) # Works as expected, the color is updated in the scene
Makie.update!(plot, markersize=2) # Works as expected, the markersize is updated in the scene

So I can see this changes the inputs, but does not really update the marker? Is this a bug or an intended element?
using GLMakie
s = Scene(camera=cam3d!)
color = Observable(GLMakie.RGBA(1.0, 0.64705884, 0.0, 1.0)) # Observable for the color of the marker
m = meshscatter!(s, Point3(0.0, 0.0, 0.0), marker=Sphere(Point3(0.0, 0.0, 0.0), 1.0), markersize=1, space=:data, color=color[])
on(color) do c
# Update the marker color whenever the color Observable changes
Makie.update!(m, color=c)
end
color[] = GLMakie.RGBA(0.0, 1.0, 0.0, 1.0) # Change the color to green to trigger the update
color[] = GLMakie.RGBA(0.0, 0.0, 1.0, 1.0) # Change the color to blue to trigger the update
new_pos = Observable(Point3(1.0, 1.0, 1.0)) # Observable for the position of the marker
on(new_pos) do p
# Update the marker position whenever the position Observable changes
Makie.update!(m, marker=Sphere(p, 1.0))
end
new_pos[] = Point3(2.0, 2.0, 2.0) # Change the position to trigger the update
Hmmm… I imagine this is how you would use Observables that are linked to the update! function pipeline that uses ComputeGraphs.
Although, @sdanisch I think the meshscatter marker not changing with the change in an input is a bug. I think I reported this for WGLMakie as well.
Anyways, Great work!
Huh, that seems to be a bug in GLMakie.
But, you can still use plot(...; attribute=observable) without a problem, in fact it pretty much does the on(x-> update!(...), obs), that you’re using.
Explicitly doing on(x-> update!(...), obs) makes mostly sense if you need to update multiple attributes, then its a big improvement!

I see. I will then just use the previous version for my simulation since I rely on that functionality until the bug is fixed.
Interesting, so for optimal runs, I should really stop using Observables as input attributes and call the listener function once for all my updates, which, now I see, is quite simple with the update! function using the new pipeline.
Thanks!
