Cool!

```julia
colors = to_colormap(:balance)
n = length(colors)
alpha = [ones(n÷3);zeros(n-2*(n÷3));ones(n÷3)]
cmap_alpha = RGBAf0.(colors, alpha)
scene1 = volume(a,algorithm=:absorption,colorrange=(-3,3),colormap=cmap_alpha)
scene2 = volume(a,algorithm=:mip,colorrange=(-3,3),colormap=cmap_alpha)

```

 ![abs_alpha](https://global.discourse-cdn.com/julialang/original/3X/6/1/61212cfccc2f83ec4d6da933f214ed560d5f46b5.jpeg)

That’s much improved, but `:absorption` is still muted (the colors are washing together?) and `:mip` still only catches the high range. Is colorrange the wrong parameter for this?

Contours look like this:

```julia
scene3 = contour(a.σ,levels=[-3,3],colormap=:balance)

```

Not sure, this is all not super well tested and used, so quirks are to be expected. I’m not 100% sure what you’re to achieve, so could be either a bug, or just still not the right parameters!

> Contours look like this:

Cool! Btw, to make it look more like absorption, you should be able to set e.g `alpha=0.5`

I’m trying to achieve something like the banner image - I want the vortex structures to be as bright and well defined as possible since they encode a bunch of information about the flow. (And they are pretty.)

Adding `alpha=0.2` is nice, but it seems to wipe out the contours near the torus. Maybe because those surfaces have less texture than the contours in the wake?

```julia
contour(a.σ,levels=[-6,6],colormap=:balance,alpha=0.2,colorrange=[-7,7])

```

I’m trying to update the Makie examples in WaterLily.jl, and I’m not sure how to get the 3C camera moves to work with the new `Figure` and `LScene` stuff.

For example, how can I zoom in on the example in the `volume` documentation.

```julia
r = LinRange(-1, 1, 100)
cube = [(x.^2 + y.^2 + z.^2) for x = r, y = r, z = r]
cube_with_holes = cube .* (cube .> 1.4)
fig,scene,_=volume(cube_with_holes, algorithm = :iso, isorange = 0.05, isovalue = 1.7)
zoom!(scene,zeros(3),1,true)

ERROR: MethodError: no method matching cameracontrols(::LScene)
Closest candidates are:
  cameracontrols(::Scene) at C:\Users\admin\.julia\packages\AbstractPlotting\ek9LT\src\scenes.jl:415

```

Try

```julia
fig, lscene, _ = ...
scene = lscene.scene

```

and continue from there!

Thanks, but I ended up removing it. (This post is two years old.)
