OpenXR/OpenVR (virtual reality support)

[realthunder]

Do you mean mixed reality? Because in VR room scale locomotion does work for a while. That's why my test project is a simple room Fcstd Video

There is not collision detection, but I fell it would be more distracting than useful.

Not really, I just mean to have a room with better graphics.

Hi kwahoo,

Thank you for all your great work on adding OpenXR support!

It seems that the last update post and pre-release build of the git repo ( https://github.com/kwahoo2/FreeCAD ) were more than 2 months ago. So development seems to have stopped/slowed down and the build of current features (e.g working HMD) looks stable ( https://www.youtube.com/watch?v=K8pXt4s0YU4 ).

I thought it might be a good idea to push the current changes to the mainline so that everyone can use it with the latest features/version.
A 'smaller' commit would also make it easier to review and see what has been added. It would also allow other people ( like me ) to implement additional stuff like edit capability in VR.

Side note: If controller support is still missing we can add that later, since there are many controllers out there (Xbox 360/One, Playstation, Oculus Touch, Vive wand, Hydra's etc, WII motes and other custom things).

This is because I've started working on a different things lately, and I'm going to return to XR view development later. I still listen for a feedback. The truth is: I have no idea if the code works for others at all. There is no point mainlining not tested code. For testing, there is a preview release.

Also, should I make pull request for OpenXR view or the OpenVR one? Which one gives more compatibility (listening feedback here)? Is there a hardware that supports OpenGL+OpenVR but does not support OpenGL+OpenXR? OpenXR was supposed to be THE VR standard, but current implementations are limited. I cannot even run OpenXR on Nvidia+Linux, because of lack of asynchronous reprojection.

Finally, after seeing how slow is mainline FreeCAD rendering, I'm going to wait for LinkStage3 merge.

Btw, do you still use these Xenial/Bionic scripts as the base for your Appimages? I would like to build a custom Appimage based on LinkStage3 brach, but I have to disable Python2/QT4 part and move to Focal, since XR libraries do not exist in older Ubuntu releases.

No, that is for debian packages. The AppImage scripts are here.

Thanks, unforunately I cannot get it working (using your repository for testing):

Code: Select all

+ test conda-fc-dev
+ docker_name=conda-fc-dev
++ date +%Y%m%d
+ date=20201026
+ conda_img_name=FreeCAD-img-Conda-Py3-Qt5-20201026-glibc2.12-x86_64
+ cat
+ bash -c ' docker build -t conda-fc-dev -f tmp.dockfile'
"docker build" requires exactly 1 argument.
See 'docker build --help'.

Usage:  docker build [OPTIONS] PATH | URL | -

Build an image from a Dockerfile

Should be fixed now.

Should be fixed now.

Thanks, it's fixed.
