Somewhere, the eye view transform is being applied twice. For now,
this hack with applying an inverse view transform corrects the bugged
lighting in the XR branch.
Hands are now basically perfect (on Vive controllers, at least,
palm pose/grip surface would really help but it's not well supported)
Head now bends properly at the bottom of the head bone and the HMD view
isn't stuck at the bottom of the head bone.
TODO: The current solution doesn't account for avatar scale or the
actual positions of their eyes. The pull-forward offset for the view
might also be too far, I'll need to get feedback on it.
Replaces the raw controller button inputs with named OpenXR actions.
There's a lot of engine components that expect raw controller inputs
like the VR teleport script. Those will have to be refactored later,
but for now this works well enough and is perfectly usable. A small
issue I've hit is the LY input working for the teleport script,
but not for smooth locomotion. I've hacked around this by having
the "walk" action bound both to LX/LY and to the Translate actions.
It's a bit janky for teleports, but it's functional.
TODO: Feedback on intuitive bindings for other controller types besides
just the HTC Vive controllers.
This still isn't ideal and it uses the Vive controller settings,
but this should work on most controllers thanks to OpenXR's built-in
action remapping and standardised button names.
This aught to be replaced with a proper set of XR input profiles,
at the moment this is *just* enough to get hardcoded button inputs
working with the existing Vive controller config.
Add missing includes on Windows.
Include GLX only on Linux.
Move openxr_platform.h include to OpenXrContext.h. To make this
possible, certain names from GLX/X11 need to be undefined in order to be
now includable in OpenXrInput.h.
