|
|
|
|
New/expanded APIs:
|
|
* osgXR/Swapchain: New Swapchain class to represent a chain of images that can
|
|
be passed to OpenXR for use in composition layers. They can be linked to
|
|
cameras for rendering, and to state sets to update the texture of mirror
|
|
objects.
|
|
* osgXR/SubImage: New simple SubImage class to specify a sub-rectangle of a
|
|
Swapchain, for use by composition layers.
|
|

|
|
composition layer handling.
|
|
* osgXR/CompositionLayerQuad: New CompositionLayerQuad class for applications
|
|
to use to implement OpenXR compositor quad layers.
|
|
|
|
Behind the scenes:
|
|
* Subaction: Tweak indentation.
|
|
* Add Quirks infrastructure.
|
|
* Handle OpenXR GL context mishandling with quirks.
|
|
* Compositor: Add internal OpenXR::CompositionLayerQuad API.
|
|
* XRState: Split image format selection into functions for shared use by new
|
|
public Swapchain API.
|
|
* XRState::XRSwapchain: Add forced alpha internal API for use by new public
|
|
APIs.
|
|
|
|
Build system:
|
|
* CMake: Explicitly find Threads with old OpenXR loaders.
|
|
|
|
Version 0.3.8
|
|
-------------
|
|
|
|
Highlights:
|
|
* Swapchain format preferences, allowing more formats to be chosen, and using
|
|
sRGB formats by default.
|
|
* Handle building as a CMake subproject.
|
|
|
|
New/expanded APIs:
|
|
* Settings::preferRGBEncoding(), Settings::allowRGBEncoding() - For choosing
|
|
preferred and allowed RGB encodings from linear, floating point (linear), and
|
|
sRGB (non-linear).
|
|
* Settings::preferDepthEncoding(), Settings::allowDepthEncoding() - For
|
|
choosing preferred and allowed depth encodings from linear, and floating
|
|
point.
|
|
* Settings::getRGBBits(), Settings::setRGBBits() - For choosing preferred
|
|
number of bits per RGB channel (for linear & float encodings only),
|
|
overriding the graphics window traits bit depths.
|
|
* Settings::getAlphaBits(), Settings::setAlphaBits() - For choosing preferred
|
|
number of alpha channel bits, overriding the graphics window traits bit
|
|
depths.
|
|
* Settings::getDepthBits(), Settings::setDepthBits() - For choosing preferred
|
|
number of depth channel bits, overriding the graphics window traits bit
|
|
depths.
|
|
* Settings::getStencilBits(), Settings::setStencilBits() - For choosing
|
|
preferred number of stencil channel bits, overriding the graphics window
|
|
traits bit depths.
|
|
* Settings::getPreferredRGBEncodingMask(),
|
|
Settings::setPreferredRGBEncodingMask(),
|
|
Settings::getAllowedRGBEncodingMask(),
|
|
Settings::setAllowedRGBEncodingMask() - Largely internal for directly
|
|
accessing the masks of preferred and allowed RGB encodings.
|
|
* Settings::getPreferredDepthEncodingMask(),
|
|
Settings::setPreferredDepthEncodingMask(),
|
|
Settings::getAllowedDepthEncodingMask(),
|
|
Settings::setAllowedDepthEncodingMask() - Largely internal for directly
|
|
accessing the masks of preferred and allowed depth encodings.
|
|
|
|
Documentation:
|
|
* Settings: Tweak comment wording for consistency.
|
|
|
|
Behaviour changes:
|
|
* Determine swapchain formats using new preferences specified in Settings,
|
|
using sRGB formats by default instead of linear.
|
|
* Choose a suitable depth/stencil fallback for when a depth swapchain cannot be
|
|
used.
|
|
* Enable gamma correction when rendering VR mirror to sRGB framebuffer.
|
|
|
|
Build system:
|
|
* Handle building as a subproject.
|
|
* Reduce minimum CMake version to 3.11.
|
|
* Add OSGXR\_WARNINGS option to enable compiler warnings (for development use).
|
|
* Drop osgXR\_INCLUDE\_DIR use since newer CMake handles automatically.
|
|
|
|
Version 0.3.7
|
|
-------------
|
|
|
|
New features:
|
|
* Implement basic Windows OpenGL graphics binding.
|
|
|
|
Windows (MSVC) build fixes:
|
|
* Session: #ifdef X11 specific workaround.
|
|
* CMake: Require osgUtil.
|
|
* Manager: Avoid undefined Mirror.
|
|
* Fix Win32 DLL imports/exports.
|
|
* Subaction: Use C++11 smart pointers for \_private to avoid undefined Private
|
|
implementation class.
|
|
* Fix build against old OpenGL headers.
|
|
|
|
ABI changes (ABI version 5):
|
|
* Subaction: Use C++11 smart pointers for \_private.
|
|
* Switch Action, ActionSet & InteractionProfile pimpls to std::unique\_ptr<>.
|
|
|
|
Version 0.3.6
|
|
-------------
|
|
|
|
Bug fixes:
|
|
* Work around Monado GL context assumptions for xrCreateSession &
|
|
xrCreateSwapchain calls.
|
|
* Permit new swapchain formats: GL\_RGB10\_A2 (for Monado on AMD) & GL\_RGBA8.
|
|
|
|
Behaviour changes:
|
|
* Report list of swapchain formats on failure to choose one.
|
|
|
|
Behind the scenes:
|
|
* Minor whitespace cleanups in src/XRState.cpp.
|
|
|
|
Version 0.3.5
|
|
-------------
|
|
|
|
Bug fixes:
|
|
* Ensure OpenXR::Action is valid before creating an action state object.
|
|
* Don't suggest empty InteractionProfile bindings to OpenXR.
|
|
|
|
Behaviour changes:
|
|
* Manager (XRState) no longer keeps counted references to ActionSets or
|
|
InteractionProfiles. The app should manage the lifetime of these objects
|
|
itself, and can now safely discard and recreate them.
|
|
* All created Actions are now provided to OpenXR even if unreferenced by any
|
|
InteractionProfile suggested bindings.
|
|
* Action setup is now treated as a separate initialisation stage. As such if
|
|
no action sets or no interaction profiles have been created, action setup
|
|
will now take place on the next update() after they are created.
|
|
|
|
New/expanded APIs:
|
|
* Manager::syncActionSet() - To inform osgXR that actions, action sets, or
|
|
interaction profiles have been altered, so it can take action to apply them
|
|
as soon as possible.
|
|
* ActionPose::Location::operator !=, ActionPose::Location::operator == - For
|
|
comparing pose location objects for equality.
|
|
|
|
Behind the scenes:
|
|
* Some minor refactoring in src/Action.cpp.
|
|
|
|
Version 0.3.4
|
|
-------------
|
|
|
|
Bug fixes:
|
|
* Fix draw pass accounting and slave cam VR mode.
|
|
|
|
Behaviour changes:
|
|
* Automatically fall back from SceneView mode if the view configuration isn't
|
|
stereo.
|
|
|
|
New/expanded APIs:
|
|
* New action APIs for exposing OpenXR actions (both input and haptics), action
|
|
sets, interaction profiles, and subactions:
|
|
* osgXR/Action: New Action, ActionBoolean, ActionFloat, ActionVector2f,
|
|
ActionPose and ActionVibration classes to represent different kinds of
|
|
XrAction.
|
|
* osgXR/ActionSet: New ActionSet class to group actions that can be activated
|
|
and deactivated together.
|
|
* osgXR/InteractionProfile: New InteractionProfile class to allows default
|
|
action bindings for interaction profiles to be suggested.
|
|
* osgXR/Subaction: New Subaction class to represent a subaction path (or top
|
|
level user path) which groups physical interactions, allowing single
|
|
actions that apply to both hands to be handled separately.
|
|
|
|
Behind the scenes:
|
|
* Add internal action management classes in OpenXR namespace.
|
|
* Wrap XrSpace in an OpenXR::Space class.
|
|
* Wrap XrPath in an OpenXR::Path class.
|
|
* Extend inline code documentation.
|
|
* Code cleanups.
|
|
|
|
Version 0.3.3 (formerly 0.4.0)

|
|
|
New/expanded APIs:
|
|
* Settings::getVisibilityMask(), Settings::getVisibilityMask() - for setting
|
|
whether osgXR should create visibility masks (when supported by the OpenXR
|
|
runtime).
|
|
* Manager::hasVisibilityMaskExtension() - for finding whether the visibility
|
|
mask extension is supported by the OpenXR runtime.
|
|
* Manager::setVisibilityMaskNodeMasks() - for setting the left and right eye
|
|
NodeMasks to use for visibility masks.
|
|
|
|
Behind the scenes:
|
|
* Implement creation, caching, and updating of visibility mask geometry for each
|
|
OpenXR view.
|
|
* Implement rendering of visibility masks to the depth buffer to reduce fragment
|
|
overhead when GPU bound.
|
|
|
|
Version 0.3.2
|
|
-------------
|
|
|
|
Bug fixes:
|
|

|
|
changes).
|
|
|
|
Behaviour changes:
|
|
* Pick depth buffer format based on GraphicsContext traits depth bits.
|
|
* Enable depth info submission at session state to allow it to be dynamically
|
|
switched without hitting a SteamVR hang during instance destruction.
|
|
|
|
Behind the scenes:
|
|
* Fix a few inconsequential compiler warnings with -Wall.
|
|
* Minor cosmetic cleanups (whitespace, explicit include).

|
|
-------------
|
|
|
|

|
|
* Manager::checkAndResetStateChanged() - to detect when VR state may have
|
|
changed, requiring app caches to be invalidated or synchronised with the new
|
|
state.
|
|
|
|
Version 0.2.1
|
|
-------------
|
|
|
|
Behind the scenes:
|
|
* Make frame view location accessors thread safe so multiple cull threads can be
|
|
used.
|
|
|
|
Version 0.2.0
|
|
-------------
|
|
|
|
API changes:
|
|
* Cleanups (moving dynamic bits out of Settings).
|
|
* Manager::update() - should be called regularly to allow for incremental
|
|
bringup and OpenXR event handling.
|
|
* Manager::setEnabled() - for triggering bringing up/down of VR.
|
|
|
|
New/expanded APIs:
|
|
* Manager::destroyAndWait() and Manager::isDestroying() - for clean shutdown
|
|
before program exit.
|
|
* Manager::syncSettings() - to trigger appropriate reinitialisation to handle
|
|
any changed settings.
|
|
* Manager::getStateString() - to get a user readable description of the current

|
* Manager::onRunning() - virtual callback when VR has started (consider setting
|
|
up desktop mirrors).
|
|
* Manager::onStopped() - virtual callback when VR has stopped (consider
|
|
removing desktop mirrors).
|
|
* Manager::onFocus() - virtual callback when VR app is running in focus
|
|
(consider resuming if paused).
|
|
* Manager::onUnfocus() - virtual callback when VR app has lost focus (consider
|
|
pausing the experience).
|
|
|
|
Behind the scenes highlights:
|
|
* Make OpenXR bringup incremental, reversible and restartable.
|
|
* Improved handling of SteamVR's messing with GL context and threading.
|
|
* Separated event handling.
|
|
|
|
Version 0.1.0
|
|
-------------
|
|
|
|
This represents early development with the API still in heavy flux.

|
|
|
It supported:
|
|
* A Manager class with virtual callbacks for configuring views.
|
|
* Desktop mirrors of the VR views.
|
