Makie.jl: mouse sensitivity too high when rotating 3D scene

[ssfrr]

MWE:

using Makie, GeometryTypes, Colors

scene = Scene()
dots = scatter(rand(10), rand(10), rand(10))
center!(scene)

When I click and drag on the scene window, it rotates very quickly (about 1cm is a full rotation). I have a relatively high DPI screen, so if it's measuring mouse movement in pixels that would make it more sensitive.

[SimonDanisch]

Good point! I need to test this on my high dpi laptop, and likely should use screen millimeter as the unit ;)

Mouse sensitivity also feels strange (too low) when panning -- I'd kinda expect the cursor to stay fixed to the scene instead of moving much faster.

[SimonDanisch]

Are you by any chance on macos? I think in a 2d scene, the mouse should always move with the scene when panning.

[pfitzseb]

No, Manjaro. I'm using a flat mouse profile though, so that might be a cause?

Edit: Pretty sure it is. The discrepancy in speed varies with speed of mouse movement.

[pbouffard]

Same thing for me, MacOS, both on a Retina laptop screen and non-Retina external monitor. Panning feels about right, though.

Is there any available workaround for this?

You can decrease rotation speed by setting ~scene.camera.rotationspeed[]~ cameracontrols(scene).rotationspeed[]

[cdsousa]

@asinghvi17, I cannot find any rotationspeed...

[asinghvi17]

Ah, you need cameracontrols(scene).rotationspeed[] @cdsousa

[pauljurczak]

The default value of cameracontrols(scene).rotationspeed[] was 0.3. Even when I set it to 0.0001, it still rotates very, very fast.

[asinghvi17]

Could you try something like:

cameracontrols(scene).rotationspeed[] = 0.01f0

to make sure that the provided value is Float32?

btw, this looks like a pretty good default to me. @SimonDanisch could you test this out on your machine? If it makes sense, I'll PR the change.

[pauljurczak]

@asinghvi17
My error. I was redefining scene object. It works just fine now. BTW, 0.01f0 is not necessary - 0.01 works just fine.

Agree with 0.01 being much better default than 0.3.

+1 for less sensitivity by default
