spacenav: init package and module #94234

lukego · 2020-07-30T13:27:16Z

Motivation for this change

This PR adds hardware support for the 3Dconnexion Spacemouse (https://www.youtube.com/watch?v=4WBTJhXpnsc) to nixpkgs in general and Blender in particular.

Specifically,

Package the Spacenav software packages spacenavd, libspnav, spnavcfg.
Add option spacenavSupport to Blender (enabled by default);
Patch Blender to recognize the device ID of the hardware unit that I bought in 2020 (have to contact Blender upstream about that patch separately.)

This works great for me! However I have to start spacenavd manually as root. (I tried writing a NixOS module to operate that but my first attempt hasn't worked and I'm a bit of a systemd n00b.)

Things done

Supports 3D input devices such as 3Dconnexion Spacemouse.

Builds Blender with support for 3D input devices such as 3Dconexxsion Spacemouse. Patched Blender to recognize the device-ID of the wireless Spacemouse that I bought in 2020. Has to be upstreamed to Blender separately. Enabled by default even though the feature is obscure because enabling has low impact (small dependency) while enabling manually has larger impact (have to compile Blender which takes a long time.)

Oh dear. I applied those suggestions that Github offered me but it seems they were only drafts and not actually working. Sorry, haven't seen this workflow on Github before with being offered changes to adopt, didn't have a workflow for testing/evaluating them beyond a quick eyeball.

Closing this PR because the review process is a bit overwhelming with all the advanced Github features and bot reviews :)

KoviRobi · 2020-08-05T14:57:47Z

I just got a SpacePilot Pro, and am interested in helping you test (and could implement a NixOS module too), we'll see if I can find the time to do so :)

KoviRobi · 2020-08-05T18:41:40Z

I don't know if there is a better way to suggest changes, but I have a couple of commits on top of yours, at https://github.com/KoviRobi/nixpkgs/commits/spacenav-nixpkgs. I reopened this, as this work is still based you yours, but I can close this and create a new PR if you want.

If you want to fold my changes into yours, you should be able to do (I think)

git remote add kovirobi-spacenav https://github.com/KoviRobi/nixpkgs.git
git fetch kovirobi-spacenav
git rebase kovirobi-spacenav/spacenav-nixpkgs

failing that, you can just git cherry-pick individual commits from mine :)

This runs the driver for 3D mice such as Space Navigator, Space Pilot or Space mouse.

KoviRobi · 2020-08-05T21:45:16Z

I have also added a service, which is currently run as root :( but I couldn't get it working otherwise.

It also turns out it works as a joystick out of the box, if you disable the mouse functionality, in which case you can just use the joystick input for OpenSCAD, though sadly not for blender.

lukego · 2020-08-06T12:22:19Z

That's awesome @KoviRobi! I've pulled your commits onto this branch. If my Git-fu is lacking in some respect feel free to open a new PR from a branch of your own and we can close this one.

Code looks good to me

Is this somewhere upstream in blender, and could we fetchpatch from there?

Last time I played with this, I opened 3 issues:

feature request: way to specify custom configuration file FreeSpacenav/spacenavd#8
This allows specifying a custom config file. We currently don't seem to configure anything?

feature request: log via syslog() instead of custom log FreeSpacenav/spacenavd#9
This introduces -l syslog, which we should probably set, to properly capture log output

feature request: make file socket configurable FreeSpacenav/spacenavd#10
The spnav.sock socket currently is hardcoded, and I'm not sure about its permissions. Did you verify this works?

I did manage to get spacenav working with this, but it's worth pointing out that spacenav joystick support is in Linux out of the box, and you can disable the annoying mouse movements with this:

services.xserver.inputClassSections = [ '' Identifier "3Dconnexion SpacePilot PRO " MatchProduct "3Dconnexion SpacePilot PRO " Driver "evdev" Option "Ignore" "on" '' ];

But blender doesn't support mouse navigation (openscad does).

The config file is something which we could potentially capture with nix, but given it's got a gui configurator and it's very floating-point not easy to calculate you just have to try and see what works, we do definitely want to support that.

Good idea

I did verify, it works (when it's launched as root, I couldn't make it work non root though :( )

Yeah, this could use some documentation, maybe the inputClassSection even a NixOS option.

Can you add some module documentation, like it's done with the nextcloud module?

The config file is something which we could potentially capture with nix, but given it's got a gui configurator and it's very floating-point not easy to calculate you just have to try and see what works, we do definitely want to support that.

So you want to give this some cooking first?

I did verify, it works (when it's launched as root, I couldn't make it work non root though :( )

GUI applications need to be launched as root? Or the spacenav daemon?

The spacenav daemon needs to be root -- though you do need write permissions to the /etc/spnav.conf, which currently I think requires a chown.

Also, because my brain is a vegetable today, I forgot your first point, the OP did say they tried to get their patch accepted upstream, not sure if they have heard anything back from them.

I'll have a think about the config file, what I meant though is that it might not be applicable to be captured by nix, as the user might want to change it too often/faster than recompiling the system/with the gui rather than just picking values.

I'll try and remember to look at this in a couple of days when I am more functional, thanks for taking a look at this PR though!

Having to no clear separation between user-wanted config and "state/calibration data" would indeed be a problem - let's iterate on that at a later point :-)

These three issues are duplicates of each other:

leenaars · 2021-01-10T15:02:58Z

And there is a version bump for spnavcfg too:

  src = fetchFromGitHub {
    owner = "FreeSpacenav";
    repo = pname;
    rev = "v${version}";
    hash = "sha256-QCHAMua4Wtn+v2fw5VdA29yg+IXHjZzT0f2VoGObFaA=";
  };

Sohalt · 2021-01-20T16:46:44Z

Can you also add the spacenav-cube-example? You can have a look at #75866 for the rationale and implementation.

flokli · 2021-06-25T10:17:27Z

For posterity: This has been implemented in #118617.
