ANGLE/UWP support checked into OSG github
Reply with quote

Hi All,

I have created a branch off OSG master for merging ANGLE/UWP support
that has been provided my members of the OSG community. The branch
is:

https://github.com/openscenegraph/OpenSceneGraph/tree/donvito-illogic-osg-illogic-github

If you want to see what changes were required the commit of the PR is:

https://github.com/openscenegraph/OpenSceneGraph/commit/a60cd972f62818d63d2198eec7dcf10fe7909d18

I am not a Windows user myself so can't test out personally, it would
be useful interested Windows users could try out the branch and if
everything works well we can merge it with OSG master. Let us know
how you get on in this thread.

Cheers,
Robert.

Hi.
Now that Windows Phone is dead, I wonder if UWP still makes any sense
to invest into.
OSG runs fine on newest Windows as it is now, so I wonder why would we
want UWP for. Xbox?

Hi Michael,

Isn't this work necessary for the Hololens?

Cheers
Raymond

It's a relatively small set of changes to the OSG.

I'm not the author of the UWP support so can't speak for the
motivation. Xbox and Hololens are two interesting areas though.

Robert.

Yeah Holo lens and I'm not 100% sure but I think if you want to put your app on the windows store it needs to use Angle.

Still keep meaning to test it on XBox.

Thomas Hogarth and AlphaPixel performed this work on behalf of a client, who I am not currently naming unless they want to step forward and identify themselves.


UWP is necessary for things like Hololens (the initial intended target of this work) and I believe XBox and all Windows Store applications. I'm not endorsing these restrictions, it's just Microsoft's decision, and our customer felt the opportunity was more compelling than the challenges, so we did what was necessary to make it work.

Effectively, OSG runs on top of ANGLE ( https://github.com/google/angle ). Here's Microsoft's own repo of ANGLE: https://github.com/Microsoft/angle


It works relatively well, and proves you can do this. Obviously, we acknowlede the vast amount of work in ANGLE and in previous OSG-on-ANGLE efforts that we stood upon. I believe the majority of new work was actually dealing with other API restrictions of UWP. THe changes embodied here might be a good template for future work on OSG/VSG to ensure better API/platform portability.


If you're interested in OSG on UWP or using it yourself, drop us a note. I'd love to see more OSG Hololens work as VR/AR is the majority of what AlphaPixel does with OSG/osgEarth.
